AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE: GEN006570 (in versions v1 r14 through v1 r10)

Title

The file integrity tool must be configured to verify ACLs. (Cat III impact)

Discussion

ACLs can provide permissions beyond those permitted through the file mode and must be verified by file integrity tools.

Check Content

If using AIDE, verify the configuration contains the acl option for all monitored files and directories. Here is an example AIDE configuration fragment. SampleRule = p+i+l+n+u+g+s+m+c+acl+xattrs+sha256 /bin SampleRule If the acl option is not present, this is a finding. If using a different file integrity tool, check the configuration per tool documentation.

Fix Text

If using AIDE, edit the configuration and add the acl option for all monitored files and directories. If using a different file integrity tool, configure ACL checking per the tool's documentation.
