All valid SUID/SGID files must be documented.

Description
There are valid reasons for SUID/SGID programs, but it is important to identify and review such programs to ensure they are legitimate.

ℹ️ Check
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.

✔️ Fix
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.
