SSL VPN – Secure Socket Layer VPN
• Uses SSL protocol for confidentiality,
authentication and integrity and then proxies to
provide authorized and secure access for private
network resource like Web, Client/Server, file
sharing etc.
• Two modes
• Clientless: Proxies web-based applications and uses inbuilt
SSL support in browsers to establish VPN and deliver web
traffic.
• Network Extension: Proxies client-server application,
requires a proprietary client application to establish VPN
and facilitate client-server application communication

What’s Missing in SSL VPN
• Performance Degradation
• SSL VPN falls prey to TCP over TCP melt-down
• Extra context switching of SSL VPN’s causes performance
loss
• Poor End User Experience
• Limited or no connectivity over low bandwidth
or high packet loss networks like
• Wireless
• DSL
• Data Cards
• Increased Support Cost
• No Site to Site VPN capabilities
© 2005-06 NeoAccel, Inc.
Why Companies are Not Buying SSL ?
• Extra context switching of SSL VPN’s causes
performance loss
• SSL VPN falls prey to TCP over TCP melt-down
• Performance degradation affects the SSL gateway and
all users
• Many companies stay with IPSec to avoid user
complaints
What can IT do?

Packet Loss Leads to Performance
Degradation
• Packet Loss is a Real World problem
• Packet loss translates to severe performance
degradation due to architectural flaw in current
SSL VPN products from the market leaders
• In the US, it is not unusual to see 5~8% packet
loss across the public internet
• 15-20% packet loss is typical in wireless networks
(i.e., 802.11)
• In some parts of Asia 50% packet loss is typical
• Worldwide average is >24% packet loss

Why ICAA?
• It is observed that other SSL VPN vendors simply tunnel
(proxy) a complete Ethernet frame over the SSL
connection to private network resulting in two TCP layers
for each packet. This results in redundant layer of
reliability which causes TCP over TCP meltdown problem.
(Slide 4)
• Many of the applications are not designed to work over
varying bandwidth lousy networks like Internet.
• There are known issues with TCP layer when working
over Internet. In case of SSL VPNs when multiple
application TCP connections are tunneled into a single
TCP connection, the effect of TCP problems is increased
exponentially. This results in frequent connection
disconnects.
© 2005-06 NeoAccel, Inc.
ICAA Benefits
• ICAA avoids the overhead of extra reliability layer induced
because of tunneling application TCP traffic into SSL VPN TCP
tunnel.
• ICAA reduces TCP packet loss recovery time by 30 times by
avoiding tunneling of TCP connection inside another TCP
connection.
• ICAA avoids the TCP layer limitations which makes TCP not
suitable for remote application connections over WAN with
varying bandwidth and congestion. ICAA avoids parameters
like TCP window size and congestion window for each
application connection. The parameters of a single SSL VPN
TCP tunnel are applied to all application connections.
• ICAA does not let application connection to flow over WAN,
thus avoiding TCP slow start problem, fragmentation and
avoids congestion control algorithm limitations for each
application connection.
• Even in 0% packet loss networks (like LAN), the number of
packets are reduced by 50% straightaway.

Why TSSL?
• It was observed that other SSL VPN vendors do
encryption/decryption at application layer which is
normally implemented at less privileged level in an OS
(Slide 3, 4). This results in slow SSL processing resulting
in high latency for applications connections
• The high context switching of CPU results in slower
packet processing, higher latency, less throughput and
low user logins/sec.
• Because SSL processing is done at user mode (less
privileged mode of OS), there is an overhead between
SSL module and SSL hardware accelerator cards. This
results in less output from SSL hardware accelerator
cards.
© 2005-06 NeoAccel, Inc.
TSSL Benefits
• TSSL avoids the CPU context switching for both SSL VPN
Gateway and Client while handling each application
connection over SSL VPN resulting in high tunnel
throughput.
• TSSL helps CPU spend less time doing non-VPN related
tasks and helps process VPN data faster resulting in low
latency and faster user logins per second.
• TSSL enables SSL VPN Gateway and SSL VPN Client to
do bulk encryption resulting in better throughput.
• TSSL reduces the communication over head between
SSL VPN Gateway and SSL accelerator card resulting in
maximum throughput and higher SSL transactions per
second.
• TSSL helps control latency added because of SSL
processing for real time traffic like VOIP and video.
© 2005-06 NeoAccel, Inc.
Why ATCE (Dynamic Compression) ?
• Other VPN solutions have a switch like
functionality for compression.
• Compression benefits are truly based on the
available bandwidth and the current load on the
VPN gateway. Other VPNs do not consider
these factors
• A ON/OFF functionality makes compression
increase more load of VPN gateway even if
compression of data is not required
© 2005-06 NeoAccel, Inc.
ATCE Benefits
• Calibrates compression benefits at regular
interval of times.
• Low bandwidth connections get more
compression benefits compared to higher
Internet bandwidth users
• Data is compressed only if data is
compressible
• Optimizes the ratio of load/bandwidth

Module 2 – SSL VPN-Plus
Module 2 focuses on creating and configuring the SSL VPN-Plus Gateway
instance that end users will establish the tunnel with. It is possible and often
useful to run multiple instances or gateways on a single device. This allows
the administrator to provide different options for user connectivity.
One example would be configuring a separate gateway for third party business
partners who need tunnel connectivity. Creating a separate gateway with a single
authentication source and other options is an effective way to plan your Remote
Access strategy.
© 2005-06 NeoAccel, Inc.

Module 3 – Users/Groups
The NeoAccel SSL VPN-Plus allows granular control of users and groups.
You will find that most of the power of this access control is based on group
membership. The ability to limit access methods, apply access control policies,
Provide resources to access, do cleanup as well as provide the user with a
customized experience is gained by the use of Group policies.
When using an external authentication source such as RADIUS or Active
Directory it is not necessary to configure users directly on the gateway
provided you have selected the Group Extraction option in the configuration
of the external authentication servers.
Upon presenting credentials to the PHAT client or Portal, the gateway will
forward that request to the authentication server and extract the users group
membership and apply configured Group Policies to that user.
© 2005-06 NeoAccel, Inc.
Authentication Servers
The SSL VPN-Plus Gateways supports the following authentication methods
•Local Database
•Active Directory with/without Group Extraction
•RADIUS with/without Group Extraction
•LDAP with/without Group Extraction
•RSA Secure ID
•Client Certificates – X.509
SSL VPN-Plus utilizes a “cascading authentication” mechanism whereby
the user credentials supplied at time of login can be validated against multiple
authentication servers. Authentication servers are bound to the Gateway instance
and not the User/Group. Order of search precedence is determined by the
administrator.

Users - Local
In many cases the administrator may want to create local users for authentication
rather than using an external authentication server. One example would be
allowing third party personnel to use the SSL VPN-Plus tunnel and rather than
adding this third party user to Active Directory simple configure a local user.

The administrator can enable certain data cleanup mechanisms for set of users belonging
to a group.
Either Browser cache cleanup can be enabled or blocking of cut/copy/paste can
be enabled for the duration of end users session.
Secure workspace can be activated such that end user will need to work inside a
secure desktop and all data will be stored in a encrypted manner on end users machine,
traces of which will be deleted at the end of users VPN session.

Access Control Policies - ACL
This screen is a repository of configured ACL’s. These ACL’s can be applied
to Groups and Security Zones to control user access. Much like firewall rules
take caution in applying these rules.

Endpoint Security Policies
Endpoint Security Policies allow the administrator to define machine specific
scans to validate whether the client computer meets the security policies of the
company. These security scans, host validation, are pre-user authentication.
The administrator can configure scans for the following items
•File
•Process
•Registry
•Ports
•Services
•WMI
•Certificate Template
EPS policies are evaluated in the following order of precedence
Zone=AND
Policy=OR
Rule=AND
© 2005-06 NeoAccel, Inc.
Endpoint Security Policies
The SSL VPN-Plus comes with approximately 100 pre-configured
Endpoint Security checks. The administrator can create custom check by
selecting the Add button.

Creating Process Policy
To create a Process policy use the Windows Task Manager to locate
the running process to test for and note the executable name.
In this case the test will check for Skype.exe running.

the File Name and full path and File Properties.
© 2005-06 NeoAccel, Inc.
EPS - Registry
The administrator can test for the Existence of Registry entries.

EPS – Registry cont.
The above example would check to determine if the client machine is
a member of the company domain
© 2005-06 NeoAccel, Inc.
EPS – Port Status
This allows the administrator to perform a basic port scan on the
Client machine to determine whether certain ports are open/closed/listening
© 2005-06 NeoAccel, Inc.
EPS - Service
This scan detects whether the client computer has a Windows service and
whether the service is Running or Not Running.
© 2005-06 NeoAccel, Inc.
EPS - WMI
WMI helps in reading dynamic database of Windows. Rules created using WMI
are used to check for health of firewall, anti-virus, anti-spyware.
© 2005-06 NeoAccel, Inc.
EPS – Certificate Template
This scan helps to do a water mark check of the end users machine to
identify a corporate issues machine
© 2005-06 NeoAccel, Inc.
Security Zones
Once the administrator has configured EPS policies, upon the client computer
establishing a tunnel and prior to authentication, the results of the EPS scan will
determine Zone membership. SSL VPN-Plus ships with 5 pre-configured Zones
and the ability to create up to 40 different security zones.
Membership of a particular zone starts at the Highest level and based upon Pass/Fail
of the EPS policies will traverse downward into lower zones where ACL’s may be
applied to limit resource access.
Zones allow the administrator to over-ride Group policies and control access based
upon the validation of the client computer.
In general one should never add an allow policy to a Security Zone with the exception
of the Quarantine Zone.
