Fix Recommendation

Configure all public directories to have the sticky bit set to prevent unauthorized and unintended information transferred via shared system resources.

Set the sticky bit on all public directories using the following command, replacing "[Public Directory]" with any directory path missing the sticky bit:

$ sudo chmod +t [Public Directory]

Check Contents

Verify all public (world-writeable) directories have the public sticky bit set with the following command:

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

If any world-writable directories are found missing the sticky bit, this is a finding.
