3.3.2

Requirement

Ensure that the actions of individual system users can be uniquely traced to those users, so they can be held accountable for their actions.

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).
