Discussion

The ability to read the MIB file could impart special knowledge to an intruder or malicious user about the ability to extract compromising information about the system or network.

Check Content

Check the file permissions for the MIB files.
# find / -name *mib* -o -name *MIB* | xargs ls -lL

If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix Text

Remove the extended ACL from the file.
# setfacl --remove-all <mib file>
