The “Internal Use Only” data classification includes the User Domain, the Work Station Domain, and the LAN domain. These domains are the most simple IT Infrastructure domains, and they will cover all the users and workstations in the company. The “Internal Use Only” classification will cover information like the company telephone directory, new employee training materials, and internal policy manuals.
The User Domain defines the people who have permissions to a company’s information system.

This domain is not the strongest link in any company’s infrastructure.
The Workstation Domain is where all the user information will be confirmed, and an account will be set up. They will need to have a user name and password that is assigned to them by the IT department, before they can access the systems, application or data. No personal devices or removable media will be allowed on the network, and all systems will undergo regular updates, and have anti-virus and anti-malware installed on each workstation for monitoring. There will also be an Access Control List (ACL) drawn up to define what access each individual will have on the network.
The LAN domain includes all data closets and physical as well as logical elements of the LAN. This domain needs strong security, being that it is the entry and exit points to the wide area network, and makes private information easily accessible to anyone. Users will be screened and authorized by the IT department head and given a special access code. The biggest threat to the LAN domain is unauthorized access. This will be monitored closely to make sure all policies are being followed.
Through my research I have found that these three domains will be most
