Title

NIS/NIS+/yp command files must not have extended ACLs. (Cat II impact)

Discussion

NIS/NIS+/yp files are part of the system's identification and authentication processes and are, therefore, critical to system security. ACLs on these files could result in unauthorized modification, which could compromise these processes and the system.

Check Content

Verify NIS/NIS+/yp files have no extended ACLs. # ls -lLRa /usr/lib/netsvc/yp /var/yp If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix Text

Remove the extended ACL from the file. # getfacl [file with extended ACL] Remove each ACE returned. # setfacl -d [ACE] [file with extended ACL]
