Secure /tmp And /var/tmp Directories On CentOS Linux

A couple days ago a CentOS Linux server that I took over administration on had some mysterious files show up in the /tmp and /var/tmp directories.

Before looking into where the issue is I needed to lock things down so no applications could be executed from these directories in the future regardless of a security flaw in the future. Below are instructions on how to secure /tmp and /var/tmp.
