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.
