Secure mode only works in SSH. As per this mode, only strong
ciphers and Message Authentication Codes (MACs) are allowed in SSH server and SSH client
connections. After enabling secure-mode:
For communication, SSH server uses a new secure-mode list made each for
ciphers and MACs.
For the SSH client, EPM is notified to change the bit dedicated to SSH
secure-mode, which hides the weak ciphers and MACs from SSH client CLI commands.
