Discussion

Enterprise Voice, Video, and Messaging Endpoint management includes the ability to control the number of user sessions and limiting the number of allowed user sessions helps limit risk related to DoS attacks. Enterprise Voice, Video, and Messaging Endpoint sessions occur peer-to-peer for media streams and client-server with session managers. For those endpoints that conference together multiple streams, the limit may be increased according to policy but a limit must still exist.

Check

Verify the Enterprise Voice, Video, and Messaging Endpoint is configured to limit the number of concurrent sessions to an organizationally defined number.

If the Enterprise Voice, Video, and Messaging Endpoint is not configured to limit the number of concurrent sessions to the limit set by local policy, this is a finding.

Fix

Configure the Enterprise Voice, Video, and Messaging Endpoint to limit the number of concurrent sessions to the limit set by local policy.
