Intranets
•
Basis for B2E: internet
supporting internal activties
•
Improve comm. inside the
company
•
Advantages
•
•
•
cross-platform
open standards
minimal user training

Characteristics of a B2E
Intranet
•
•
physical tech: LAN with Ethernet
•
•
firewall sw for security
middleware: software which handles
physical comm. (TCP/IP based)
standard web applications:
browsers, e-mail clients, file sharing

How To Use B2E
Intranets
•
Information access for employees:
centralised databases with a common interface
•
Collaboration and teamwork:
distribute information, remote working groups
•
Internal business transactions:
increase efficiency and reduces paperwork
4626. Introd to Computer Science
Extranets
Business Alliances
•
Link intranets of different companies
(e-marketplaces)
•
Activities between trusted business partners
Functionalities
• place orders
• check stock level
• confirm inoice status
• exchange business information
4626. Introd to Computer Science
Extranets
with Public Networks
•
use public, open comm. lines without additional
security mechanisms
•
•
low cost, but low security (and high risk)
protection: firewalls and logons

Extranets with VPN
•
•
use public, open comm. lines
•
VPNs are becoming the preferred method:
economical and secure enough
an special protocol creates a virtual tunnel
across the intranets

Extranets
with Private Networks
•
•
•
•
physically attached lines (leased)
high cost
high security levels
extent of access for external
users (only business partners)
