Control Statement
Restrict privileged accounts on the system to [Assignment: organization-defined personnel or roles].
Supplemental Guidance
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.
OT Discussion
When OT components (e.g., PLCs) cannot support the logging of privileged functions, other system components within the authorization boundary may be used (e.g., engineering workstations or physical access monitoring).
