Fix Recommendation

The root role is required.

Determine the existence of any set-UID programs that do not belong on the system, and work with the owners (or system administrator) to determine the best course of action in accordance with site policy.

Check Contents

The root role is required.

# find / \( -fstype nfs -o -fstype cachefs -o -fstype autofs \
-o -fstype ctfs -o -fstype mntfs -o -fstype objfs \
-o -fstype proc \) -prune -o -type f -perm -4000 -o \
-perm -2000 -print

Output should only be Solaris-provided files and approved customer files.

Solaris-provided SUID/SGID files can be listed using the command:

# pkg contents -a mode=4??? -a mode=2??? -t file -o pkg.name,path,mode

Digital signatures on the Solaris Set-UID binaries can be verified with the elfsign utility, such as this example:

# elfsign verify -e /usr/bin/su
elfsign: verification of /usr/bin/su passed.

This message indicates that the binary is properly signed.

If non-vendor provided or non-approved files are included in the list, this is a finding.
