AC-6 (05)—Least Privilege | Privileged Accounts
>Control Description
>FedRAMP Baseline Requirements
No FedRAMP-specific parameter values or requirements for this baseline.
>Discussion
Privileged accounts, including super user accounts, are typically described as system administrator for various types of commercial off-the-shelf operating systems. Restricting privileged accounts to specific personnel or roles prevents day-to-day users from accessing privileged information or privileged functions. Organizations may differentiate in the application of restricting privileged accounts between allowed privileges for local accounts and for domain accounts provided that they retain the ability to control system configurations for key parameters and as otherwise necessary to sufficiently mitigate risk.
