Title

The Enterprise Voice, Video, and Messaging Endpoint must be configured to produce session (call detail) records containing the source of the connection. (Cat II impact)

Discussion

Session records are commonly produced by session management and border elements. Many Enterprise Voice, Video, and Messaging Endpoints are not capable of providing session records and instead rely on session management and border elements. Enterprise Voice, Video, and Messaging Endpoints capable of producing session records provide supplemental confirmation of monitored events. Enterprise Voice, Video, and Messaging Endpoints that communicate beyond these defined environments must generate session records. 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. Detailed records are typically produced by the session manager but can be augmented by nontelephone endpoint records.

Check Content

Verify the Enterprise Voice, Video, and Messaging Endpoint produces session records containing the source of the connection. If the Enterprise Voice, Video, and Messaging Endpoint does not produce session records containing the source of the connection, this is a finding.

Fix Text

Configure the Enterprise Voice, Video, and Messaging Endpoint to produce session records containing the source of the connection.
