Title

There must be no .shosts files on SLEM 5. (Cat I impact)

Discussion

The .shosts files are used to configure host-based authentication for individual users or the system via SSH. Host-based authentication is not sufficient for preventing unauthorized access to the system as it does not require interactive identification and authentication of a connection request or for the use of two-factor authentication.
