| If audit data were to become compromised, then forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve.
This requirement pertains to securing the VPN log as it is stored locally, on the box temporarily, or while being encapsulated.
This requirement can be achieved through multiple methods, which will depend upon system architecture and design. Some commonly employed methods include ensuring log files receive the proper file system permissions, and limiting log data locations.
Audit information includes all information (e.g., log records, audit settings, and audit reports) needed to successfully audit information system activity.
This requirement only applies to components where this is specific to the function of the device (e.g., IDPS sensor logs, firewall logs). This does not apply to audit logs generated on behalf of the device itself (management). |
