What is CMMC AC.2.010?

CMMC stands for Cybersecurity Maturity Model Certification, a unified cybersecurity standard developed to enhance the protection of controlled unclassified information (CUI) within the supply chain of the Department of Defense (DoD).

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. This is particularly important for system-level accounts, which, if compromised, can lead to substantial damage.

Moreover, CMMC AC.2.010 also plays a crucial role in regulatory compliance. Many industries, particularly those dealing with sensitive information such as defense, healthcare, and finance, require stringent account management as part of their cybersecurity regulations. By adhering to CMMC AC.2.010, organizations not only improve their security but also ensure they are meeting necessary compliance requirements.

In conclusion, CMMC AC.2.010 is more than just a regulatory requirement. It represents a commitment to robust account management practices that enhance cybersecurity, protect sensitive information, and ensure regulatory compliance. As IT professionals and system engineers, understanding and implementing this guideline is an important step toward a more secure and reliable information system.
