AC.2.010, in particular, is a specific practice within the CMMC framework. It necessitates that organizations manage network and information system accounts, including system-level accounts in a manner corresponding to the AC (Access Control) domain. This includes identifying account types (i.e., default, guest, administrative, and service accounts), establishing conditions for group and role membership, and managing identifiers for persons or devices. The AC.2.010 practice plays an integral role in mitigating the risk of unauthorized access to information systems, thereby elevating the overall cybersecurity maturity of an organization.

According to CMMC AC.2.010, it is necessary to effectively manage network and information system accounts, which includes accounts at the system-level. Essentially, it requires organizations to have a robust system in place for managing user accounts on their networks and information systems. This includes all types of accounts, from end-user accounts to system-level accounts, which have elevated privileges and can make significant changes to system configurations.

It is vital to ensure these accounts are properly managed. This management includes not only creation, modification, and deletion of accounts as necessary, but also monitoring and controlling the actions that these accounts can perform. For instance, system-level accounts should only be used for tasks that require elevated privileges and should be closely monitored for any potential misuse.

Why is CMMC AC.2.010 Important?

The importance of CMMC AC.2.010 lies in its role in enhancing cybersecurity. By effectively managing network and information system accounts, organizations can significantly reduce the risk of unauthorized access and data breaches.
