TMA-AIX-4.6.3.2
Ensure /etc/shosts.equiv and /etc/rhosts.equiv are removed
Descripción
The recommendation is to remove both the /etc/shosts.equiv and /etc/rhosts.equiv file. This is a consequence of the recommendation to not use HostbasedAuthentification. The recommendation is to not use HostbasedAuthentification unless there is a documented need already exists the logical consequence is to remove these files, if they exist, to lower the risk of accidental activation. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
