I have identified at least three IT infrastructure domains affected by the “Internal Use Only” data classification standard. The infrastructure at Richman Investments will include the basic domains as the User Domain, Workstation Domain, and the LAN Domain. This should cover all the users and access to the internet and everything in between. • User Domain The User Domain defines the people who access an organization’s information system.
The User Domain will enforce an acceptable use policy (AUP) to define what each user can and cannot do with any company data shall he or she have access to it. Its like a rulebook that employees must follow. Users are responsible for their use of IT assets. The User Domain is the weakest link in the IT infrastructure. Any user responsible for computer security must understand what brings someone to compromise the data of an organization.
• Workstation Domain. The Workstation Domain is where must users are approved on the company network. On the workstation domain, the staff should have the necessary access to be productive. To access any workstation, a user will need to be first verified, then setup with an account to be logged in with a username and password assigned by the IT departments set by Richman Investments. All computers have maintain regular updates and continuous antivirus protection for monitoring. Also, no personal devices will be allowed on the network.
• LAN Domain. The local area network (LAN) Domain is a collection of computers connected to one another or to a common medium. All LAN domains include data closets, physical elements of the LAN, as well as logical elements to be designated by authorized personnel. It needs strong security and access controls. Its can access company-wide systems, applications, and data from the LAN domain. The LAN support group is in charge of the LAN Domain. The biggest threat to the LAN domain is Unauthorized access to most anything (the LAN, the systems, & the data).
