Vulnerability discussion

Audit review, analysis, and reporting covers information security-related auditing performed by organizations including, for example, auditing that results from monitoring of account usage, remote access, wireless connectivity, mobile device connection, configuration settings, system component inventory, use of maintenance tools and nonlocal maintenance, physical access, temperature and humidity, equipment delivery and removal, communications at the information system boundaries, use of mobile code, and use of VoIP. Organizations retain audit records until determining they are no longer needed for administrative, legal, audit, or other operational purposes. This includes, for example, retention and availability of audit records relative to Freedom of Information Act (FOIA) requests, subpoenas, and law enforcement actions. Organizations develop standard categories of audit records relative to such types of actions and standard response processes for each type of action. The National Archives and Records Administration (NARA) General Records Schedules provide federal policy on record retention.For Voice Video systems, session events produce Call Detail Records (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 loss or alteration of these records could allow an adversary to perform attacks undetected.

Check content

Review the CDR policy and supporting documentation for the CDR storage requirements. The organization must retain CDRs for at least one year to provide support for after-the-fact investigations of security incidents and to meet regulatory and organizational information retention requirements. If the CDR policy or supporting documentation does not require CDRs to be retained for at least one year, this is a finding.

Fix text

Develop and document in the CDR policy or supporting documentation the retention of CDR for at least one year. This supports after-the-fact investigations of security incidents and meets regulatory and organizational information retention requirements.
