Seven Domains of IT Infrastructure Seven domains can be found in a typical IT infrastructure. They are as follows: User Domain, Workstation Domain, LAN Domain, LAN-to-WAN Domain, Remote Access Domain, WAN Domain, and System/Application Domain.
Explanation:
User Domain : The User Domain covers all theusers (of any rank) that haveaccess to the other six domains.
RISKS:
-
User can destroy data in application(intentionally or not) and delete all
- User can insert infected CD or USBflash drive into the work computer
Workstation Domain : A computer of an individual user where the production takes place
RISKS:
- The workstation’s OS can have a known software vulnerability thatallows a hacker to connect remotelyand steal data.
- A workstation’s hard drive can fail causing lost data
LAN Domain : Contains all of the workstations,hubs, switches, and routers. TheLAN is a trusted zone
RISKS:
-
A worm can spread through the LANand infect all computers in it.
- LAN server OS can have a knownsoftware vulnerability.
WAN Domain : Stands for Wide Area Network and consists of the Internet and semi-private lines
RISKS:
- Service provider can have a major network outage.
- Server can receive a DOS or DDOS attack.
- A FTP server can allow anonymously uploaded illegal software
LAN / WAN Domain : The boundary between the trusted and un-trusted zones.The zones are filtered with a firewall
RISKS:
- Weak ingress/egress traffic filteringcan degrade performance.
- A firewall with unnecessary portsopen can allow access from the Internet
System / Application Storage Domain : This domain is made up of user-accessed servers suchas email and database
RISKS:
- A fire can destroy primary data
- A DOS attack can cripple the organization’s email
Remote Access Domain :The domain in which a mobileuser can access the local network remotely, usually through a VPN
RISKS:
- Communication circuit outage candeny connection.
- Remote communication from officecan be unsecured.
- VPN tunneling between remotecomputer and ingress/egress routercan be hacked
