Check: GEN003790

HP-UX 11.23 STIG: GEN003790 (in version v1 r8)

Title

The services file must not have an extended ACL. (Cat II impact)

Discussion

The services file is critical to the proper operation of network services and must be protected from unauthorized modification. If the services file has an extended ACL, it may be possible for unauthorized users to modify the file. Unauthorized modification could result in the failure of network services.

Check Content

Check the permissions of the /etc/services file. # ls -lL /etc/services If the permissions include a "+", the file has an extended ACL, this is a finding.

Fix Text

Remove the optional ACL from the file. # chacl -z /etc/services
