Check: GEN001361

HP-UX 11.31 STIG: GEN001361 (in versions v1 r19 through v1 r13)

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 -lL /var/yp/* 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 /var/yp/*
