Information
Files with the setgid bit set will allow anyone running these files to be temporarily assigned the group id of the file. While many system files depend on these attributes for proper operation, security problems can result if setgid is assigned to programs allowing reading and writing of files, or shell escapes.
NOTE: Nessus has not performed this query, and this check is only provided for informational purposes.
Solution
Establish a weekly automated or manual process to generate a list of setgid files on the system and compare it with the prior list.
To create a list of setgid files:
# find / -perm -2000 > setgid-file-list
NOTE: The frequency may be increased to daily, if necessary, in accordance with the contingency plan.
