Fix Recommendation

If intermediary services for remote access communications traffic are provided, configure the ALG to use cryptography to protect the integrity of remote access sessions.

Check Contents

If the ALG does not serve as an intermediary for remote access traffic (e.g., web content filter, TLS and webmail), this is not applicable.

Verify the ALG uses cryptography to protect the integrity of remote access sessions.

If the ALG does not use cryptography to protect the integrity of remote access sessions, this is a finding.
