CMMC Description
Ensure that the actions of individual system users can be uniquely traced to those users so they can be held accountable for their actions.
CMMC Clarification
You need to capture information in audit logs. This ensures that you can trace the actions you audit to a specific user. This may include capturing information from users, including: * user IDs * source and destination addresses * time stamps. * Such information helps track actions to an individual. Example You are the IT administrator for your organization. You want to ensure that you can trace all remote access sessions to a specific user. You configure the VPN device to capture the following information for all remote access connections: * source and destination IP address * user ID * machine name * time stamp * user actions during the remote session. This lets you trace these actions to a specific user.
800-171 Description
Ensure that the actions of individual system users can be uniquely traced to those users, so they can be held accountable for their actions.
800-171 Discussion
This requirement ensures that the contents of the audit record include the information needed to link the audit event to the actions of an individual to the extent feasible. Organizations consider logging for traceability including results from monitoring of account usage, remote access, wireless connectivity, mobile device connection, communications at system boundaries, configuration settings, physical access, nonlocal maintenance, use of maintenance tools, temperature and humidity, equipment delivery and removal, system component inventory, use of mobile code, and use of Voice over Internet Protocol (VoIP).
