Title

The /etc/nsswitch.conf file must not have an extended ACL. (Cat II impact)

Discussion

The nsswitch.conf file (or equivalent) configures the source of a variety of system security information including account, group, and host lookups. Malicious changes could prevent the system from functioning or compromise system security.

Check Content

Verify /etc/nsswitch.conf has no extended ACL. AIX does not use the /etc/nsswitch.conf file. This check is not applicable. Procedure: # aclget /etc/nsswitch.conf If extended permissions are enabled, this is a finding.

Fix Text

Remove the extended ACL from the /etc/nsswitch.conf file. # acledit /etc/nsswitch.conf
