About the TLS session resumption feature in Global security

NetBackup uses TLS (Transport Layer Security) to secure communications between NetBackup hosts. Each new TCP connection between NetBackup hosts must perform a TLS handshake and verify the peer identity before NetBackup sends traffic across that connection.

The session resumption feature optimizes the TLS handshake so that a full handshake is not required for every TCP connection. The security level determines how long NetBackup allows a TLS session to be reused before a full handshake is required.

You can set the security level interval as follows:

This feature currently only applies to NBCA. ECA to be supported in a future release.
