Prevent privileged accounts from accessing unprivileged environments
Ensure privileged accounts can't be used in unsecured setups to limit risk.
Plain language
This control ensures that accounts with special privileges can't be used in unsafe situations. Imagine having a special key to your business; if you use it in a risky area or environment, someone could copy it and use it to break into your business. This control stops privileged accounts from being used in unprotected environments, which can prevent potential security breaches.

Official control statement
Privileged accounts (excluding local administrator accounts) cannot logon to unprivileged operating environments.
Why it matters
Using privileged accounts in unsecured environments risks exposing credentials to malware, enabling attackers to escalate access and compromise systems.
Operational notes
Enforce logon restrictions so privileged accounts cannot access unprivileged workstations; review logs and alert on any blocked sign-in attempts.
Implementation tips
- IT team should identify all privileged accounts in the organisation by reviewing user account permissions and categorising them according to their level of access.
- System administrators should configure systems to prevent privileged accounts from logging into unprivileged environments. This can be achieved by setting up access restrictions in the system's access control settings.
- Security officers should regularly review and update policies to ensure they reflect the separation between privileged and unprivileged environments. This can be done by documenting procedures that detail these access restrictions.
- IT security staff should implement a monitoring system to alert when a privileged account attempts to access an unprivileged environment. This could involve setting up alerts within existing security software to track login attempts.
Audit / evidence tips
- AskAre privileged accounts restricted from logging into unprivileged environments?
- GoodSystem logs and settings show that privileged accounts are unable to access unprivileged environments, with proper restrictions documented
- AskIs there documentation explaining how privileged access is controlled and monitored?
- GoodThere is clear documentation outlining the procedures for managing privileged access, including a list of authorised users and system configurations
