CMMC 1.0 Practice AU.3.050 Requirement:
Limit management of audit logging functionality to a subset of privileged users.
CMMC 1.0 AU.3.050 Requirement Explanation:
System administrators have full control of their systems, this allows them to modify everything including audit logs. They can potentially delete logs indicating that they have violated a security policy. To avoid this you do not allow system administrators to control and carry out auditing tasks.
Example CMMC 1.0 AU.3.050 Implementation:
Separate system administration duties from audit logging management duties. Persons that are responsible for creating users, resetting passwords, installing software, and other admin tasks should not have access to your syslog server and SIEM.
CMMC 1.0 AU.3.050 Scenario(s):
- Scenario 1:
You are a small company and have one system administrator who manages all of your systems. You do not want him to be able to delete audit logs off of your syslog server or carrying out audit activities using your SIEM. To accomplish this you do not provide him access to these systems. If you temporarily need his technical assistance on your syslog server or SIEM you provide him temporary access and supervise him while he completes his assigned task.
