Vulnerability discussion

Audit record content to satisfy control requirements includes time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, filenames involved, and access control or flow control rules invoked. Event outcomes can include indicators of event success or failure and event-specific results (e.g., the security state of the information system after the event occurred).For Voice Video systems, session events produce CDRs used for traffic and forensic analysis. The CDR contains the who, what, where, when, and how for the Voice Video elements handling signaling and media traffic. The CDR must also include metadata including time stamps, source and destination addresses, source and destination participants, success/fail indications, status, and Quality of Service (QoS).

Check content

Review the CDR policy and supporting documentation for defined additional, more detailed information to be included in the CDR. If the CDR policy or supporting documentation does not contain defined additional, more detailed information to be included in the CDR, this is a finding.

Fix text

Develop and document in the CDR policy or supporting documentation more detailed information to be included in the CDR.
