Appendix I: Security overview

SUID ssage

TORQUE uses setuid (SUID) permissions in a single location so as to validate the identity of a user request. This is accomplished using the pbs_iff tool which is SUID root and performs the following actions:

parse specified server hostname and port
connect to specified server port using reserved/privileged port
determine UID of executing user
report UID and socket port info of caller to server
verify response from server

/etc/hosts usage

In systems where security is a major concern, please be aware that some security experts consider adding the compute nodes to the /etc/hosts file to be more secure than using ACL lists.
