Level 4

Make use of user groupings

Make use of user groupings to determine authorization (for example, via groups in ActiveDirectory or LDAP or by using AuthZProxy or Grouper).

Review active accounts

Send a list of active accounts to the business owner monthly to review; ideally this will be done via a trackable mechanism such as Service Now.

Disable account access

Disable account access if user leaves University or changes jobs such that they no longer have a business need to access the information; the best way to do this is by using the central authentication service.

Remote login must only permit the use of encrypted communications

Remote login to all servers must only permit the use of encrypted communications such as ssh. Windows servers must enforce a minimum of 128-bit encryption for Terminal Services and Remote Desktop communication. All servers running SSH must use a minimum of protocol version 2. Use of VPN is advised where available.

Enforce password complexity

Server operators should implement LDAP, AD, IAM as best practice where possible. Two factor authentication is required for any system handling L3/medium risk data and above.

Ensure application owners are identified to you

Document the name, department, and role of the informed IT liaison (practice manager or service owner), contact information, and the data classification level. This should be stored in a secure local repository (such as Service Now) or a spreadsheet which is stored securely.
