Set the sticky bit on all public directories using the following command, replacing "<public_directory_name>" with any directory path missing the sticky bit:

$ sudo chmod +t <public_directory_name>

Check Contents

Verify that all public directories have the public sticky bit set by using the following command:

$ sudo find / -type d -perm -002 ! -perm -1000

If any public directories are found missing the sticky bit, this is a finding.
