ℹ️ Check
All remote sessions must be conducted via encrypted services and ports.
Check that SSH is enabled:
# svcs svc:/network/ssh
STATE STIME FMRI
online Nov_03 svc:/network/ssh:default
Ask the operator to document all configured external ports and protocols.
If any unencrypted connections are used, this is a finding.
✔️ Fix
Configure SSH to be enabled.
# svcadm enable svc:/network/ssh
