Vulnerability discussion

Individual authenticators for Voice Video endpoints are typically PKI certificates. In many cases, developers ship information system components with factory default authentication credentials to allow for initial installation and configuration. Default authentication credentials are often well known, are easily discoverable, and present a significant security risk. For Voice Video systems, the Voice Video endpoints must authenticate as a network device using 802.1X and register with a session manager. Managing the unique certificates for each Voice Video endpoint ensures communications are restricted to only known devices. Requiring reauthentication periodically reduces the risk of rogue devices attempting to imitate authorized devices.

Check content

Review the Voice Video system security plan (SSP) for the time period for Voice Video endpoints to reauthenticate to Voice Video session managers. If the Voice Video SSP does not contain the time period for Voice Video endpoints to reauthenticate to Voice Video session managers, this is a finding.

Fix text

Develop and document in the Voice Video SSP the time period for Voice Video endpoints to reauthenticate to Voice Video session managers. Consideration for bandwidth and latency must be taken into account. Setting this value too high may allow unauthorized Voice Video endpoints to impersonate service.
