RHEL 10 must not have any ".shosts" files on the system.

STIG ID: RHEL-10-700690  |  SRG: SRG-OS-000080-GPOS-00048 |  Severity: medium (CAT II)  |  CCI: CCI-000213 |  Vulnerability Id: V-281272

Vulnerability Discussion

The ".shosts" files are used to configure host-based authentication for individual users or the system via Secure Shell (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.

Check

Verify RHEL 10 does not have any ".shosts" files on the system with the following command:

$ sudo find / -name .shosts

If a ".shosts" file is found, this is a finding.

Fix

Configure RHEL 10 to not have any ".shosts" files on the system.

Remove any found ".shosts" files from the system with the following command:

$ sudo rm /[path]/[to]/[file]/.shosts
