1. Introduction
1.1. History of company
HSBC is considered on of the world’s largest banking and financial
services. The main corporate branch is in London, UK. But is has almost 7200 branches
in over 80 countries around the world, starting with Asia all the way through till the
Americas. HSBC has over 89 million customers.
We have chosen this corporation because it is one of the largest corporations that
have to deal with individuals.
Their logo is: The world’s local bank, to keep in touch with customer
information, and to show that their logo is true, they are using a widely spread network
in order to access any information any time anywhere.
1.2. Purpose of Network (in general)
Communication is very important for people that serve a lot of things in our
life, such as in business field that link all the organizations in one network. HSBC use
advanced technology to make everything work will to individuals, organization and
business "HSBC serves around 95 million personal customers and over 3.5 million
commercial customers. To meet the needs of these customers, HSBC employs over
300,000 employees speaking over 100 languages.
On 31 December 2010, HSBC’s Total assets amounted to almost US$2,500
billion". Network known as Macmillan dictionary define it as “a set of computers that
are connected to each other so that each computer can send and receive information to
and from other computers”.
Nowadays, business needs communication system to contact all branches of
the organization together that to control and manage all the business work from small
screen. So, the main reason for network that to link, share and exchange files that makes
it faster and easier to do the work inside or outside the company.
2. Problem statement
2.1 . Problem statement regarding business
Internet banking in HSBC is increasing and growing rabidly which makes the
transactions become easier, convenient and faster. It is the latest improvement and
development that has taken a place in the field of banking transactions to make it
professionally done and to reduce the long waiting-lines. Although it has been added by
HSBC
3
the banks organizations to facilitate the bank processes, it still faces some serious
problems during your banking transactions through the Internet that may that may dictate
and you to go yourself directly to the bank instead of doing it online. These problems
may be related to the customers or to the bank itself. For the customers, they have to
have at least a basic knowledge of the Internet and computers in order to carry out the
Internet banking correctly. While some customers are kind of beginners in dealing with
Internet so that they find it hard to handle their bank transaction through the Internet. In
addition to that, some of them don’t even trust on Internet banking where in some cases a
small mistake like pressing on a wrong button, may lead to big problems. As for the
HSBC, it faces some difficulties in their network like disruption of systems that is back
to some reasons occurs when the mother network become under pressure when the
number of users becomes large. This is one of the reasons that may lead to disruption of
the customers online bank transactions and hamper them to complete their operations
which force them to waste their time and go to the bank.
2.2 . Problem statement regarding networks
HSBC is the most the most organization that has achieved remarkable success
in recent years in banking transactions. It has more than 1421 branches in the UK in
addition to the international branches all over the world.
They manage their banking work professionally and they provide the best
professional and personal banking services.
Their main objective is to satisfy the customers’ needs and protect their security
accounts. They are facing some problems like business bank problems and bank
complaints that are related to mortgages and bank loans between the customers and the
band. In addition to that, banking work conflicts between employers and managers.
3. Connection Method
3.1. Wired technologies
Wired technology is available from many years as this is secure method of
transferring HSBC Bank files and data within the organization by using of
network cables with the help of network device called switch. The other
application of wired technologies is to communicate to other parties both
internal and external platform. Currently, this is the most reliable way to
transmitting/receiving data or voice on the planet. The Internet itself transmits
a large amount of data through fiber optic cabling but also employs a large
HSBC
4
amount of T1/T3 lines that run over standard copper wiring. For purposes of
this article, "wired" refers to copper wiring and does not include fiber optic
technologies. The table below portrays the pros and cons of wired technology.
For the most part, wired technology is very reliable. The telephone system operates
using wired technology and provides a 99.999% uptime. This is also known as the
“five 9s of reliability." Although wire is susceptible to interference by loud machinery
(A/C units, electric motors, etc) various solutions, such as shielded cable can be used
to solve these problems. Shielded or armored wiring is used to protect against weather
and other types of negative externalities. Compared to wireless solutions, wired is
very cheap. The equipment is generally cheaper, as well as the cost of maintenance.
Generally, copper wiring has a very long life expectancy. The QoS is excellent
because wired connections eliminate the need for establishing an end-to-end
connection every time. Speed is also a huge advantage for HSBC Bank for using
wired connections. Using a group of wires (like a telephone or Ethernet cable) allows
each conductor to handle a certain amount of information. Think of it like an
automotive transmission. The more gears you have, the great control you have over
the speed of the automobile.
On the negative side, wired connections are not always realistic. Some rural
areas HSBC Bank are still not wired for broadband Internet connections. This forces
users to subscribe to satellite access. Ethernet cables can run a maximum of 100
meters before the signal needs to be boosted. This can cause problems if you don't
have an environment that allows this luxury. Remember that the longer the cable is,
the more signal loss occurs and the signal travels down the wire. This is why special
cables have been developed to help preserve the strength of the signal. However, the
use of such technology usually comes at a significantly higher price.
Network transmission media can communicate ether wireless through radio
waves and infrared signals or wired throughout coaxial cables, optical fiber and
twisted pairs. A wired technology have been known and used before many years ago,
and it’s become popular in the early 1900’s. (Rodriguez, 2002). It used for money
transaction specifically, bank transaction even so there are no cash moved. The
majority of people have used an ATM card to buy something and that is a wire
transfer as well. And there is another type that is when you sign up for automatic bill
HSBC
5
purchasing through your bank. This kind of bill paying is becoming more popular as
technology makes it easier and safer to use.
3.1. 1. Coaxial Cables
Coaxial cables are transmission lines for high-frequency signals. The dimensions
of the cable are controlled to give an accurate, steady conductor spacing, which is
needed for it to function efficiently as a radio frequency line. It is used for
computer networks. It carries a high- frequency or broadband signal and is ideal
for broadband telecommunications. It is also widely installed for use in business
and corporation Ethernet and other types of LAN (www.epanorama.net., 2012).
3.1. 2 Optical Fibers
An optical fiber is most advanced tool for effective data flow for HSBC Bank for
data transfer through transparent fiber which is made of pure glass(silica) that helps
in transmitting any type of primary or secondary data through wired LAN(Local area
network) . The optical fiber network wire is widely used to transmit the huge volume
of data of various forms effectively as compare to metal wires which is only good for
transferring the electricity only. The application of fiber optic technology is applied
in various means to transfer secondary data like images, movies, and wrapped data
bundles and effectively used for detecting sensors gadgets and fiber lasers. .
Optical fibers are made up of transparent core covered by cladding materials with
lower index of refraction with a dim light is provided for deduction purpose that
support the paths of transverse model multi-model fibers (MMF) and single-mode
fibers(SMF). The designing and connecting the fiber networks is most crucial for
money transfer jobs assignment as this need a special effort to join all the fibers
correctly and then spliced together for smooth data flow.
3.2. Wireless technologies
Wireless internet technology generates a network by transferring radiofrequency signals among your computers to share information. It is not using wire
that all computers in bank broadcast their information to one another using radio
signals, but has significantly hindered the privacy of these individuals. Internet
banking is use accounts from anywhere using wireless Internet service. Timely
distribution of information to clients, in wireless networking, a peer-to-peer wireless
network indicates that each computer can connect directly with all other computer on
HSBC
6
the network. However, HSBC use client and server wireless networks. The wireless
networks that use client/severs have an access point. An access point is a wired
controller that receives and send outs data to the wireless adapters installed in each
computer. According to (Macari J. & Caminero D.) "Wireless Local Area Network
(WLAN) is 802.11b. WLAN operates at up to 11 megabits per second and has a range
of 100-1000 feet". A number of wireless network companies ("Hot Spot operators")
are actively building Wi-Fi networks in Banks. That HSBC must ensure that
information that is transferred wirelessly is secure from hackers.
How do bank make wireless technology useful?
Banks use wireless technology in internet banking. The client can
access accounts using wireless internet service. It provides for real-time
dissemination of information on clients. Banks also use the cellular or mobile smart
phones technology as a wireless technology to conduct business. Mobile banking
allows the consumer to transact business without going to the bank. Mobile banking
gives a more cost efficient way for these banks, helping them decrease costs and
charges to clients for transactions, and permitting these clients to have real-time
access to information related to their bank accounts. These factors should translate
into more clients to register with the banks and to have transactions more often
(www.online-distance-learning-education.com, 2012)
The Mobile Network Operator (MNO) provides the mobile phone and the
ability to use the Mobile phone for providing banking services to the consumer
(www.online-distance-learning-education.com, 2012)
The bank’s mobile banking options include:
• Leveraging the Mobile Network Operator (MNO) bearer channel and infrastructure
to extend its payments franchise to mobile facilities as a channel
• Leveraging the Mobile Network Operator (MNO) brand, distribution network, and
extended customer base to target new market segments
• Allowing a MNO to use the bank’s financial license and/or infrastructure to become
a bank.
4. Types of networks based on physical scope
A computer network is a set of computers and devices that are liked internally
by contact channels to let communication between users and to share or exchange of
HSBC
7
resources. HCBS is used computer network for many reasons, such as communication
and sharing hardware, files, data and information.
4.1 Wireless Local Area Network:
It is a computer network interconnecting computers using network media in a
limited area such as a home, office, or a bank. LAN’s characteristics include higher
data-transfer rates, smaller geographic area, and lack of a need for leased
transformation lines.
LAN's network topology illustrates the interconnecting devices and
network parts in a pattern. The most common data link layer and physical layer used
for LAN for a long time is switched ethernet. The Internet Protocol (TCP/IP) is used
as a standard for higher layers. One or more linked switches connected to a router,
cable or ADSL modem for Internet access are used to complete smaller LANs.
Redundant links with spanned tree protocol being used for preventing loops,
managing different traffic types via quality of service (QoS), and segregating traffic
with VLANs are the characteristics of larger LANs. Switches, firewalls, routers load
balancers, and sensors are contained also by Larger LANs (www.netscout.com,
2012).
LANs can also communicate with other LANs through leased lines,
leased services, or by using virtual private network or VPN technologies. A LAN can
be classified as a metropolitan area network (MAN) or a wide area network (WAN)
(www.netscout.com, 2012).
The Local Area Network (LAN) for a bank would be similar to any other LAN
but being strict on security by placing Firewalls and Security and avoiding open
wireless access points. The bank may need to be audited for security
(www.netscout.com, 2012).
4.2 Personal area network:
A personal area network - PAN - is a computer network organized around a
corporate head office of HSBC Bank like Eg: Hongkong, Dubai, and New Delhi.
Personal area networks typically involve a mobile computer, a cell phone and/or a
handheld computing device such as a PDA. You can use these networks to transfer
files including email and calendar appointments, digital photos and music.
Personal area networks can be constructed with cables or wirelessly. USB and
FireWire technologies often link together a wired PAN while wireless PANs typically
HSBC
8
use Bluetooth or sometimes infrared connections. Bluetooth PANs are also called
piconets.
Personal area networks generally cover a range of less than 10 meters (about 30 feet)
4.3 Home area network
HSBC Bank home network or home area network (HAN) is a residential local
area network (LAN)[citation needed] for communication between digital devices
typically deployed in the home, usually a small number of personal computers and
accessories, such as printers and mobile computing devices. An important function is
the sharing of Internet access, often a broadband service provisioned by fiber-to-thehome or via Cable Internet access, Digital Subscriber Line (DSL) or mobile
broadband by Internet service providers (ISPs). If an ISP only provides one IP
address, a router including network address translation (NAT), proxy server software
and typically a network firewall, allows several computers to share the external IP
address. The router function may be assumed by a PC with several network interfaces,
but a dedicated router device is more common, often including a wireless access
.point, providing Wi-Fi access
4.4 Wide Area Network:
The Wide Area Network (WAN) covers a large geographical area, and
use communications circuits to connect the intermediate nodes. WAN design and
performance depend on their lease communications circuits from telephone
companies or other communications carriers. 2 Mbps, 34 Mbps, 45 Mbps, 155 Mbps,
625 Mbps or are different transmission rates for WAN (or sometimes considerably
more). Organizations supporting WANs using the Internet Protocol or IP are known
as Network Service Providers (NSPs). These form the core of the Internet
(erg.abdn.ac.uk., 2012).
HSBC
9
Typical "mesh" connectivity of a Wide Area Network
The efficiency of communication techniques also depend on the characteristics
of The characteristics of the transmission facilities lead to an emphasis on efficiency
of communications techniques in the design of WANs. Controlling the volume of
traffic and avoiding excessive delays is important. Since the topologies of WANs are
likely to be more complex than those of LANs, routing algorithms also receive more
emphasis. Many WANs also implement sophisticated monitoring procedures to
account for which users consume the network resources. This is, in some cases, used
to generate billing information to charge individual users (erg.abdn.ac.uk., 2012).
According to (basher, 2007)"The computers that are connected to the
WANs are generally connected through the public networks and they can also be
connected through the satellites". WAN networks are built using the leased lines and a
router is linked to the end of each one and a hub is connected to the other end. A
number of computers with this hub and other hubs and switches are linked. The
greatest symbol of WAN is internet that is the largest network in the world. WAN is
improving time-to-market that facilitated the bank to easily add branches anyplace.
4.5 Campus Area Network:
A Campus Area Network (CAN) interconnects some local area networks
(LANs) within a corporate campus. Campus area network of a bank links several
banks to the main headquarters. A campus area network is between a local area
network and a metropolitan area network (MAN) or wide area network (WAN) in
size.
4.6 Metropolitan area network:
A Metropolitan Area Network (MAN) is one of a number of types of
networks (see also LAN and WAN). A MAN is a relatively new class of network, it
serves a role similar to an ISP, but for corporate users with large LANs. There are
three important features which discriminate MANs from LANs or WANs:
The network size falls intermediate between LANs and WANs. A MAN typically
covers an area of between 5 and 50 km diameter. Many MANs cover an area the size
of a city, although in some cases MANs may be as small as a group of buildings or as
large as the North of Scotland.
HSBC
10
A MAN (like a WAN) is not generally owned by a single HSBC BANK. The
MAN, its communications links and equipment are generally owned by either a
consortium of users or by a single network provider who sells the service to the users.
This level of service provided to each user must therefore be negotiated with the
MAN operator, and some performance guarantees are normally specified.
A MAN often acts as a high speed network to allow sharing of regional
resources (similar to a large LAN). It is also frequently used to provide a shared
connection to other networks using a link to a WAN.
4.7 Enterprise private network:
HSBC enterprise private network is a computer network that helps Bank with a
number of disparate offices connects those banks branches to each in a secure way
over a network. An enterprise private network is mainly set up to share computer
resources.
These networks were mainly operated over telecommunications networks. During
1990s as Internet technology evolved, a new type of network called virtual private
networks originated. This type of network was built over public infrastructure, and the
data was encrypted to protect it from eavesdroppers.
Nowadays, networks built by HSBC Bank are called enterprise private networks
when privacy is maintained through security procedures and tunneling protocols like
Layer 2 Tunneling Protocol.
Some of the advantages of an enterprise private network are:
 The messages are secure because they are encrypted.
 They are cost effective and scalable.
 They help to centralize IT resources.
 They enable business continuity.
4.8 Virtual private network
If you use the internet you can connect to virtual private network by two
ways a web browser or with a software VPN client. Banks obviously use virtual
private network "VPNs typically require remote users of the network to be
authenticated, and often secure data with firewall and encryption technologies to
prevent disclosure of private information to unauthorized parties" according to
HSBC
11
(Wikipedia). That is provides a communication between officers and those who
travels abroad to a central organizational network. VPN need not have limited
security features, such as authentication or content encryption. Virtual Private
Network that is setup could be used to isolate traffic of different user contacts over an
underlying network with powerful security features. VPN are divides into two types;
remote access VPN and site to site VPN. First, Site to site VPN lets you to have a
secured communication between locations through open internet. If HSBC bank use
site to site VPN your bank can save a great deal of money, as you can use cheaper
means always on connections such as domestic broadband rather than expensive
leased lines among sites. Remote access VPN is used by banks that have staff work in
location outside the office. You can communicate into the office network over dial up
phone/isdn lines or over broadband from anyplace.
4.9 Internetwork
An Internetwork is two or more connected of computer networks or network
segments via a common routing technology. It is called internetwork that is short two
connected of computer networks. According to (SHEIKH, A) "Two or more networks
or network segments connected using devices that operate at layer 3 (the 'network'
layer) of the OSI Basic Reference Model, such as a router. Any interconnection
among or between public, private, commercial, industrial, or governmental networks
may also be defined as an internetwork" . Recently use, interconnected networks use
the Internet Protocol. There are three types of internetworks, depending on who
administers and who participates in them: Intranet, Extranet and Internet. An intranet
defend is a set of networks, practice internet protocol. An extranet is an internetwork
that is restricted to one organization or entity but which also has specific connections
to the networks of one or more that HCBS bank not used it.
4.10 Global Area Network:
A Global Area Network or GAN is made of different interconnected
WANs in a limited geographical area.
4.11 Internet:
The vast use of Internet protocol suite is the set of communications protocols
used by HSBC bank for the Internet based online banking transactions and similar
networks, and generally the most popular protocol stack for wide area networks. It is
commonly known as TCP/IP, because of its most important protocols: Transmission
HSBC
12
Control Protocol (TCP) and Internet Protocol (IP), which were the first networking
protocols defined in this standard
TCP/IP provides end-to-end connectivity specifying how bank data should be
formatted, addressed, transmitted, routed and received at the destination. It has four
abstraction layers, each with its own protocols. From lowest to highest, the layers are:
-
The link layer (commonly Ethernet) contains communication technologies for
a local network.
-
The internet layer (IP) connects local networks, thus establishing
internetworking.
-
The transport layer (TCP) handles host-to-host communication.
-
The application layer (for example HTTP) contains all protocols for specific
data communications services on a process-to-process level (for example how a web
browser communicates with a web server).
-
The TCP/IP model and related protocols are maintained by the Internet
Engineering Task Force (IETF).
4.12 Intranets and extranets:
An "intranet" is the generic term for a collection of private HSBC Bank computer
networks within an organization. An "extranet" is a computer network that allows
controlled access from the outside for specific online business or educational
purposes. Intranets and extranets are communication tools designed to enable easy
information sharing within workgroups,
How intranet helps HSBC Bank operations?
In essence, an intranet is a business' own private HSBC Bank website. It is a
confidential business network that uses the same underlying structure and network
protocols as the internet and is protected from unauthorized users by a firewall.
Intranets enhance existing communication between employees and provide a
common knowledge base and storage area for everyone in customers business. They
also provide users with easy access to HSBC BANK data, systems and email from
their desktops.
Because intranets are secure and easily accessible via the internet, this enables
staff to do work from any location simply by using a web browser. This can help
HSBC
13
small businesses to be flexible and control office overheads by allowing employees to
work from almost any location, including their home and customer sites.
Other types of intranet are available that merge the regular features of intranets
with those often found in software such as HSBC Bank. These are known as online
offices or web offices. Creating a web office will allow you to organize and manage
information and share documents and calendars using a familiar web browser
function, which is accessible from anywhere in the world.
Types of content found on intranets:
 administrative - calendars, emergency procedures, meeting room bookings,
procedure manuals and membership of internal committees and groups
 corporate - business plans, client/customer lists, document templates, branding
guidelines, mission statements, press coverage and staff newsletters
 financial - annual reports and HSBC BANK performance
 IT - virus alerts, tips on dealing with problems with hardware, software and
networks, policies on corporate use of email and internet access and a list of
online training courses and support
 marketing - competitive intelligence with links to competitor websites,
corporate brochures, latest marketing initiatives, press releases, presentations
 human resources - appraisal procedures and schedules, employee policies,
expenses forms and annual leave requests, staff discount schemes, new
vacancies
 individual projects - current project details, team contact information, project
management information, project documents, time and expense reporting
 external information resources - route planning and mapping sites, industry
HSBC BANKs, research sites and search engines
What is an extranet?
HSBC extranet is similar to an intranet but it is made accessible to selected
external partners such as business partners, suppliers, key customers, etc, for
exchanging data and applications and sharing information.
HSBC
14
As with an intranet, an extranet can also provide remote access to corporate
systems for staff that spends lots of time out of the office, for instance those in sales
or customer support, or home workers.
Extranet users should be a well-defined group and access must be protected by
rigorous identification routines and security features.
Why HSBC use an extranet?
HSBC banking and financial Businesses operations of all sizes are under
increasing pressure to use online ordering, electronic order tracking and financial
management system.
At the same time small Banks are keen to meet the demands of larger banks like
HSBC in terms of working flexibly, adopting new technologies and enabling the
exchange of business information and transactions.
Extranets offer a cheap and efficient way for businesses to connect with their
trading partners. It also means that your business partners and suppliers can access the
information they need 24 hours a day.
The ability of the extranet to automate the trading tasks between you and your
trading partners can lead to enhanced business relationships and help to integrate your
business firmly within their supply chain.
5. Network Classification
5.1.1 Network Architecture
Network architecture is the design of a communication system that includes the
backbones, routers, switches, wireless access points, access methods and protocols
used. It is similar to extensible operating systems (SPIN, Synthesize and many
others). A bank's network architecture allows Application Customized Code to be
dynamically deployed in the network. The most famous banking architecture
network is BIAN that defines the standards for bank architecture that focuses on
semantic inoperability (www.bptrends.com, 2012).
5.1.2 Active Networking
Active networking is a pattern of communication that allows packets
flowing through a telecommunications network to dynamically modify the operation
HSBC
15
of the network. It is composed of execution environments called a node operating
system which has capacity to support more than one execution environments. One of
its parts, the active hardware is capable of routing or switching as well as executing
code within active packets. It is different from the traditional network architecture
which seeks robustness and stability by attempting to remove complexity and the
ability to change its fundamental operation from underlying network components.
Active network components can be implemented by network processors and overlay
networks. It allows the possibility of highly tailored and rapid "real-time" changes to
the underlying network operation such as sending code along with packets of
information allowing the data to change its form (code) to match the channel
characteristics (www.bptrends.com. (2012).
5.1.3 Client–server

Clients
Is a small machine that will link with specific server that is mean, there is
software or hardware that downloaded to the user's machine. That makes users and
software to be managed centrally by central server location Instead of downloads
them on all individual system. Clients are beneficial to all people because the
information will be access by the clients in the same time that is good solution for
publics. While many thin clients run on small hardware, it is unfeasible to incorporate
rich graphical user interfaces. To use the client, an input device (keyboard) and
viewing device (display) is usually the basic requirements. Some may not even
require a mouse.

Servers:
Computer or device that manages network is called server. The function of
server that is to manage and dedicated the performances based on different server
tasks. There are two types of servers, real- time server that is present data, immediate
messaging, video and telephone recourses. The other type is non real-time
communication for example, integrated messaging voicemail, email, SMS and fax. As
well it had a voice server, and special client's server for shares market. HSBC has a
server that is a mail transfer agent or MTA. Mail server is an application that gets
incoming e-mail from local user's within the same area and remote senders and
forwards outgoing e-mail for delivery. Java Server Pages it is a Java technology that
HSBC
16
helps software developers serve dynamically created web pages based on HTML,
XML. HSB also used fax server is downloaded in LAN server that lets computer
users who are linked to the LAN to send and deliver fax messages. Other server called
file server that linked computer to the network that provide a place to shared access
data such as; computer files (document, voice record, pictures and databases). That
can access by the people who work in HSBC bank. Print server is linked to
computers and the person sends order to print server that connected to one or more
than one printer.
5.2.1 Network topology
HSBC banking operation is executed by the simplest form, a peer-to-peer (P2P)
network is created when two or more PCs are connected and share resources without
going through a separate server computer. A P2P network can be an ad hoc
connection—a couple of computers connected via a Universal Serial Bus to transfer
files. A P2P network also can be a permanent infrastructure that links half-dozen
computers in a small office over copper wires. Or a P2P network can be a network on
a much grander scale in which special protocols and applications set up direct
relationships among users over the Internet.
The initial use of P2P networks in business followed the deployment in the early
1980s of free-standing PCs. In contrast to the minima in frames of the day, such as the
VS system from Wang Laboratories Inc., which served up word processing and other
applications to dumb terminals from a central computer and stored files on a central
hard drive, the then-new PCs had self-contained hard drives and built-in CPUs. The
smart boxes also had onboard applications, which meant they could be deployed to
desktops and be useful without an umbilical cord linking them to a mainframe.
Many Bank employees felt liberated by having dedicated PCs on their desktops. But
soon they needed a way to share files and printers. The obvious solution was to save
files to a floppy disk and carry the disk to the intended recipient or send it by
interoffice mail.
A network consists of multiple computers connected using some type of interface,
each having one or more interface devices such as a Network Interface Card (NIC)
and/or a serial device for PPP networking. Each computer is supported by network
HSBC
17
software that provides the server or client functionality. The hardware used to
transmit data across the network is called the media. It may include copper cable,
fiber optic, or wireless transmission. The standard cabling used for the purposes of
this document is 10Base-T category 5 Ethernet cable. This is twisted copper cabling
which appears at the surface to look similar to TV coaxial cable. It is terminated on
each end by a connector that looks much like a phone connector. Its maximum
segment length is 100 meters
5.2.2 Bus network:
A bus network is an arrangement in a local area network (LAN) by HSBC Bank in
some countries in which each node (workstation or other device) is connected to a
main cable or link called the bus. A bus network is simple and reliable. If one node
fails to operate, all the rest can still communicate with each other. For a major
disruption to take place, the bus itself must be broken somewhere. Bus networks are
easy to expand. Additional nodes can be added anywhere along the bus.
There are several limitations to the bus network topology. The length of the bus is
limited by cable loss. A bus network may not work well if the nodes are located at
scattered points that do not lie near a common line. In situations like this, a ring
network, mesh network, or star network may prove more flexible and more cost
effective.
5.2.3 Star network:
A star network is a local area network (LAN) in which all nodes (HSBC Bank
workstations or other devices) are directly connected to a common central Server
computer. Every HSBC bank workstation is indirectly connected to every other
through the central computer. In some star networks, the central computer can also
operate as a workstation.
The star network with five workstations (or six, if the central computer acts as a
workstation). Each workstation is sphere, the central computer is shown as a larger
sphere, and connections are shown as straight lines. The connections can be wired or
wireless links.
The star network topology used by HSBC banks that works well when
workstations are at scattered points. It is easy to add or remove workstations.
If the workstations are reasonably close to the vertices of a convex polygon and the
system requirements are modest, the ring network topology may serve the intended
HSBC
18
purpose at lower cost than the star network topology. If the workstations lie nearly
along a straight line, the bus network topology may be best.
In a star network, a cable failure will isolate the workstation that it links to the
central computer, but only that workstation will be isolated. All the other workstations
will continue to function normally, except that they will not be able to communicate
with the isolated workstation. If any workstation goes down, none of the other
workstations will be affected. But if the central computer goes down, the entire
network will suffer degraded performance or complete failure. If redundancy is
required, the mesh network topology may be preferable.
6. Basic hardware components
HSBC bank provide good networks to interconnect network there are basic
hardware components such as, Network Interface Cards (NICs), Bridges, Hubs,
Switches, and Routers. In this part will include some of hardware components that
HSBC bank uses them.
6.1 Repeaters:
HSBC Bank generally uses network repeaters to regenerate incoming electrical,
wireless or optical signals. With physical media like Ethernet or Wi-Fi, data
transmissions can only span a limited distance before the quality of the signal
degrades. Repeaters attempt to preserve signal integrity and extend the distance over
which data can safely travel.
Actual network devices that serve as repeaters usually have some other name. Active
hubs, for example, are repeaters. Active hubs are sometimes also called "multiport
repeaters," but more commonly they are just "hubs." Other types of "passive hubs" are
not repeaters. In Wi-Fi, access points function as repeaters only when operating in socalled "repeater mode."
Higher-level devices in the OSI model like switches and routers generally do not
incorporate the functions of a repeater. All repeaters are technically OSI physical
layer devices.
6.2 Hubs
Hubs it is looks like rectangular box, it takes its power from wall outlet
therefore it made from plastic. The basic function of hubs is links several Ethernet
devices and establishes a network segment which works together. According to
(SHEIKH, A) "a network hub contains multiple ports. When a packet arrives at one
HSBC
19
port, it is copied unmodified to all ports of the hub for transmission. The destination
address in the frame is not changed to a broadcast address". There are three different
types of hubs; active hubs, passive hubs, and intelligent hubs. Active hub called a
repeater it executing the amplification, Passive hub work as a channel used for the
data. Finally, intelligent hubs witch put in additional qualities to active hubs that is
significant for the business. According to (Mitchell, n.d) "a hub joins multiple
computers together to form a single network segment. On this network segment, all
computers can communicate directly with each other", So banks use hubs to link all
computers together. Hubs contain eight, 12, 16, and even 24 ports.
6.3 Switches
HSBC Bank uses number of network switches or switching hubs that connects
network segments or network devices. The term commonly refers to a multi-port
network bridge that processes and routes data at the data link layer (layer 2) of the
OSI model. Switches that additionally process data at the network layer (layer 3) and
above are often referred to as layer-3 switches or multilayer switches.
A switch is a telecommunication device which receives a message from any
device connected to it and then transmits the message only to that device for which
the message was meant. This makes the switch a more intelligent device than a hub
(which receives a message and then transmits it to all the other devices on its
network.) The network switch plays an integral part in most modern Ethernet local
area networks (LANs). Mid-to-large sized LANs contain a number of linked managed
switches. Small office/home office (SOHO) applications typically use a single switch,
or an all-purpose converged device such as a residential gateway to access small
office/home broadband services such as DSL or cable internet. In most of these cases,
the end-user device contains a router and components that interface to the particular
physical broadband technology. User devices may also include a telephone interface
for VoIP.
An HSBC Bank Ethernet switch operates at the data link layer of the OSI model
to create a separate collision domain for each switch port. With 4 computers (e.g., A,
B, C, and D) on 4 switch ports, A and B can transfer bank data back and forth, while
C and D also do so simultaneously, and the two conversations will not interfere with
one another. In the case of a hub, they would all share the bandwidth and run in half
duplex, resulting in collisions, which would then necessitate retransmissions. Using a
HSBC
20
switch is called micro segmentation. This allows computers to have dedicated
bandwidth on point-to-point connections to the network and to therefore run in full
duplex without collisions.
A network switch or switching hub is a computer networking device that
connects network segments or network devices. The term commonly refers to a multiport network bridge that processes and routes data at the data link layer (layer 2) of
the OSI model. Switches that additionally process data at the network layer (layer 3)
and above are often referred to as layer-3 switches or multilayer switches.
A HSBC Bank switches is a telecommunication device which receives a message
from any device connected to it and then transmits the message only to that device for
which the message was meant. This makes the switch a more intelligent device than a
hub (which receives a message and then transmits it to all the other devices on its
network.) The network switch plays an integral part in most modern Ethernet local
area networks (LANs). Mid-to-large sized LANs contain a number of linked managed
switches. Small office/home office (SOHO) applications typically use a single switch,
or an all-purpose converged device such as a residential gateway to access small
office/home broadband services such as DSL or cable internet. In most of these cases,
the end-user device contains a router and components that interface to the particular
physical broadband technology. User devices may also include a telephone interface
for VoIP.
Role of HSBC Banks switches in networks:
HSBC Bank switches may operate at one or more layers of the OSI model, including
data link and network. A device that operates simultaneously at more than one of
these layers is known as a multilayer switch.
A modular network switch with three network modules (a total of 24 Ethernet and 14
Fast Ethernet ports) and one power supply.
While switches may learn about topologies at many layers, and forward at one or
more layers, they do tend to have common features. Other than for high-performance
applications, modern commercial switches use primarily Ethernet interfaces.
At any layer, a modern switch may implement power over Ethernet (PoE), which
avoids the need for attached devices, such as a VoIP phone or wireless access point,
HSBC
21
to have a separate power supply. Since switches can have redundant power circuits
connected to uninterruptible power supplies, the connected device can continue
operating even when regular office power fails.
6.4 Routers
In some countries HSBC Bank had adopted the routers to connect where
branches in the city with packet-switched networks such as the Internet, a router is a
device or, in some cases, software in a computer, that determines the next network
point to which a packet should be forwarded toward its destination.
The HSBC Bank router is connected to at least two networks and decides which
way to send each information packet based on its current understanding of the state of
the networks it is connected to. A router is located at any gateway (where one network
meets another), including each point-of-presence on the Internet. A router is often
included as part of a network switch.
A HSBC Bank router create or maintain a table of the available routes and their
conditions and use this information along with distance and cost algorithms to
determine the best route for a given packet. Typically, a packet may travel through a
number of network points with routers before arriving at its destination. Routing is a
function associated with the Network layer (layer 3) in the standard model of network
programming, the Open Systems Interconnection (OSI) model. A layer-3 switch is a
switch that can perform routing functions.
An edge router is a router that interfaces with an asynchronous transfer mode
(ATM) network. A brooder is a network bridge combined with a router.
For HSBC Bank computer users who have high-speed Internet connections
such as cable, satellite, or DSL, a router can act as a hardware firewall. This is true
even if the home or business has only one computer. Many engineers believe that the
use of a router provides better protection against hacking than a software firewall,
because no computer Internet Protocol address are directly exposed to the Internet.
This makes port scans (a technique for exploring weaknesses) essentially impossible.
In addition, a router does not consume computer resources as a software firewall does.
Commercially manufactured routers are easy to install, reasonably priced, and
available for hard-wired or wireless networks.

7. Network Security
7.1. Firewalls
Internet is a gradually more unsafe place, mainly as network attacks have
develop from a hacker’s as a job to a sophisticated and benefits from business.
Security is the most important thing for banks to protect their clients information by
providing a strong online security system, HSBC use some protocols to protect
security. Firewalls use easy rules to selectively block network and Internet traffic. For
example, your firewalls can block employees from access www.YouTube.com or
www.Facebook.com. Internet users can easily circumvent firewall blocking
techniques. FTP servers can use a different websites can proceed as gateways to
blocked sites without your firewall knowing. A fire wall is a set of connected
programs that place at network access server, which protect from other users and
other groups of network to get through recourses of private network. HSBC uses a
multiple fire walls to make sure that personal information for clients saved and
protected. A fire wall is limited to a specific people that they have authorized to
access. It designed as a strong protector from unauthorized people such as hackers. A
fire wall has two types of network layer and application layer. HSBC bank use this
technology to protect it information from unauthorized people.
7.2. Bank Security Systems
Bank security systems are composed of several levels and components whose aim is
to protect clients' money, and the bank and their assets. The following are some
security systems being place by banks (finmark, 2012):
7.2.1. Security Cameras
High technology cameras with high resolutions are installed all over the banks
to allow law enforcers to view every angle of the bank and see specific details that
may ordinarily be able to be seen.
7.2.2. Vault Security
The present banks need two keys to open the bank vault to make it difficult for
bank vaults to be robbed. This protects the bank's assets and clients' deposits from
thieves or robbers.
7.2.3. Safe deposit Boxes
HSBC
23
It is a good option for the clients to pay for a bank safe deposit box to hold
valuable goods since every measure of safety is taken to ensure that your belongings
are protected.
7.3. Encryption
Encryption is the conversion of data into a form, called a cipher text that cannot be
easily understood by unauthorized people. Decryption is the process of converting
encrypted data back into its original form, so it can be understood.
The use of encryption/decryption is as old as the art of communication. In wartime, a
cipher, often incorrectly called a code, can be employed to keep the enemy from
obtaining the contents of transmissions. (Technically, a code is a means of
representing a signal without the intent of keeping it secret; examples are Morse code
and ASCII.) Simple ciphers include the substitution of letters for numbers, the
rotation of letters in the alphabet, and the "scrambling" of voice signals by inverting
the sideband frequencies. More complex ciphers work according to sophisticated
computer algorithms that rearrange the data bits in digital signals.
HSBC bank uses this technology for making online big payment through bank to bank
operations where money transfer order easily recover the contents of an encrypted
signal, the correct decryption key is required. The key is an algorithm that undoes the
work of the encryption algorithm. Alternatively, a computer can be used in an attempt
to break the cipher. The more complex the encryption algorithm, the more difficult it
becomes to eavesdrop on the communications without access to the key.
Encryption/decryption is especially important in HSBC Bank wireless
communications. This is because wireless circuits are easier to tap than their hardwired counterparts. Nevertheless, encryption/decryption is a good idea when carrying
out any kind of sensitive transaction, such as a credit-card purchase online, or the
discussion of a HSBC BANK secret between different departments in the
organization. The stronger the cipher -- that is, the harder it is for unauthorized people
to break it -- the better, in general. However, as the strength of encryption/decryption
increases, so does the cost.
In recent years, a controversy has arisen over so-called strong encryption. This refers
to ciphers that are essentially unbreakable without the decryption keys. While most
companies and their customers view it as a means of keeping secrets and minimizing
fraud, some governments view strong encryption as a potential vehicle by which
HSBC
24
terrorists might evade authorities. These governments, including that of the United
States, want to set up a key-escrow arrangement. This means everyone who uses a
cipher would be required to provide the government with a copy of the key.
Decryption keys would be stored in a supposedly secure place, used only by
authorities, and used only if backed up by a court order. Opponents of this scheme
argue that criminals could hack into the key-escrow database and illegally obtain,
steal, or alter the keys. Supporters claim that while this is a possibility, implementing
the key escrow scheme would be better than doing nothing to prevent criminals from
freely using encryption/decryption.
7.4. Authentication
HSBC Bank used the authentication process to determine whether someone or
something is, in fact, who or what it is declared to be. In private and public computer
networks (including the Internet), authentication is commonly done through the use of
logon passwords. Knowledge of the password is assumed to guarantee that the user is
authentic. Each user registers initially (or is registered by someone else), using an
assigned or self-declared password. On each subsequent use, the user must know and
use the previously declared password. The weakness in this system for transactions
that are significant (such as the exchange of money) is that passwords can often be
stolen, accidentally revealed, or forgotten.
For this reason, HSBC Bank internet business and many other transactions
require a more stringent authentication process. The use of digital certificates issued
and verified by a Certificate Authority (CA) as part of a public key infrastructure is
considered likely to become the standard way to perform authentication on the
Internet.
8. Conclusion
All banks and organizations need network to facilitate the communication
between employees and customers from computer networking. Computers are
becomes more advances and it is developed quickly that to match the improvement in
organization performance and how it is related to each other. Networking is used in
banks and corporations to upload and exchange data inside and outside the bank also,
it is link all the computers together. HSBC bank which is one of the largest banking
HSBC
25
institutions and financial services in the world, as it increases the number of branches
and offices than 10,000 offices worldwide to serve more than 125 million customers
in 83 countries. That by using systems is important to connect the spread branches
and departments to communicate effectively and corporate efficiently. This report
explains the networking system of HSBC bank. Network is important because without
networks somebody can to have a call every bank and give your details and then
every time you take out money they have to check all the banks another time to keep
them update on your account. With networks, every bank can see your account, what
going on in your account and it saves having to get somebody call other banks every
time you make a taking out your money also, it saves money for bank. They use
Optical Fibers and wireless communication methods to maintain the connection and
the data transmission between their distributed branches. Banks use optics fiber and
copper as a wired technologies, computers, scanners, smart phones, Personal Digital
Assistants and many other devices are used as wireless technologies. Moreover, this
report clarified the types of networks that HSBC bank uses based on the physical
scopes which are wide area network (WAN) and local area network (LAN). They use
client/server architecture to handle the network applications and bus topology for
greater reliability and enlarged network. This report also talked about the basic
hardware components that HSBC bank uses in their networking systems which are the
hubs, switches and routers. To secured data and safe exchange are important for all
banks, HSBC banks are using firewall, encryption and authentication for their
network security. Computer networking systems have become a significant factor that
assured safe, uncomplicated, costless and high-speed communication between offices
and branches.
9. Recommendation
Banks need telecommunications to make its costs efficient. There are
different technologies that can help banks in developing their telecommunications
systems. Some of these networks like local area network, wide area network, campus
area network, global area network, network architecture, active networks, security
technologies, wireless technologies, and coaxial cables help in increasing the bank’s
security, which will make the bank more convenient to the clients. Each one of the
past networks has its specific functions and advantages to help in generating more
profit to the bank as well as more customers.
