Insecure encryption algorithm - Perfect Forward Secrecy
Description
The application uses cipher algorithms that expose all messages made during the communication if the current private key is compromised.
Impact
Obtain sensitive information that is being transmitted or has been stored.
Recommendation
Enable Perfect-Forward-Secrecy in the server side, by allowing Ciphersuites that contain DHE and ECDHE on its names.
Threat
Unauthorized attacker from adjacent network that has compromised a private key.
Expected Remediation Time
⌚ 15 minutes.
