The Enterprise Voice, Video, and Messaging Session Manager must protect session (call) records from unauthorized modification.

If session records were to become compromised, then forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve. To ensure the veracity of session records, the information system and/or the application must protect session information from unauthorized modification. 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.
