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.

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.
