Title

The Unified Communications Session Manager must produce session (call) records containing the identity of the initiator of the call. (Cat II impact)

Discussion

Without the capability to generate session records, it is difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible. Session records are generated from several components within the Voice Video system (e.g., session manager, session border control, gateway, gatekeeper, or endpoints). Session record content that may be necessary to satisfy this requirement includes, for example, type of connection, connection origination, time stamps, outcome, user identities, and user identifiers. Additionally, an adversary must not be able to modify or delete session records.

Check Content

Verify the Unified Communications Session Manager produces session records containing the identity of the initiator of the call. The identity of the initiator of the call in this context would be the device ID or the address of the MAC or IP. For Unified Communications Session Managers that have the concept of a user rather than device, this requirement is not applicable. If the Unified Communications Session Manager does not produce session records containing the identity of the initiator of the call, this is a finding.

Fix Text

Configure the Unified Communications Session Manager to produce session records containing the identity of the initiator of the call.
