This module provides secure configuration of your base OS with hardening.

true
if you want to remove SUID/SGID bits from any file, that is not explicitly configured in ablacklist
. This will make every Chef run search through the mounted filesystems looking for SUID/SGID bits that are not configured in the default and user blacklist. If it finds an SUID/SGID bit, it will be removed, unless this file is in yourwhitelist
.dry_run_on_unknown = false
likeremove_from_unknown
above, only that SUID/SGID bits aren't removed. It will still search the filesystems to look for SUID/SGID bits but it will only print them in your log. This option is only ever recommended, when you first configureremove_from_unknown
for SUID/SGID bits, so that you can see the files that are being changed and make adjustments to yourwhitelist
andblacklist
.
