Secure the /tmp partition on FreeBSD   IMPORTANT NOTE:  This document is based on FreeBSD.  The concepts should be similar across operating systems, but the commands will very likely be different.  Also, never assume the directory structures exist in your system as written in the document.  Never blindly follow security instructions -- read, review, compare, apply as it fits your system. Log onto the server as root: Is the /tmp directory in its own partition? Edit /etc/fstab Do you see a /tmp partition?  If YES, then move to step B; otherwise move to step C. Modify /etc/fstab to change the definition for /tmp Change what is present for /tmp to rw,nosuid,nodev Skip to step D Modify /etc/fstab to create a new /tmp partition and have it point to your current /tmp directory The typical format is "Device Mountpoint FStype Options Dump Pass#" So you might have something like /hard_drive_device_name /tmp ufs rw,nosuid,nodev 2 2 Link /var/tmp to /tmp cd /var && mv ./tmp/* /tmp/ && rm -rf tmp && ln -s /tmp tmp NOTES: The /etc/fstab entry means it will be mounted automatically on boot up. nosuid, noexec are to help protect against hackers putting root kits in /tmp and building / executing them IMPORTANT NOTE:  This document and all linked document is being provided as a good will gesture to the Parallels H-Sphere community and to others who may benefit from its use.  Dynamic Net, Inc. makes no representations implied or explicit as to their value or warranty.
