The Juniper SRX Services Gateway must securely configure SSHv2 FIPS 140-2/140-3 validated Keyed-Hash Message Authentication Code (HMAC) to protect the integrity of maintenance and diagnostic communications for nonlocal maintenance sessions.
An XCCDF Rule
Description
To protect the integrity of nonlocal maintenance sessions, SSHv2 with HMAC algorithms for integrity checking must be configured. Nonlocal maintenance and diagnostic activities are activities conducted by individuals communicating through an external network (e.g., the internet) or internal network. The SSHv2 protocol suite includes Layer 7 protocols such as SCP and SFTP, which can be used for secure file transfers.
