CHAPTER 28 System Security

28.3 Security Programs

There are a number of PD programs you can get to help make your system more secure. Some packages you might consider installing are:

For any program of this type you need to make sure that you protect the programs and databases from tampering. It doesn't help if, e.g. with Tripwire, you compare an altered file against an altered database. The best way to prevent tampering is to store the master copies on a physically write-protected disk or off-line.

You might have logs sent to another machine, so that they can't be altered on this machine.

Many of these programs are archived on the COAST (Computer Operations, Audit, and Security Technology) archive at Purdue University, ftp://coast.cs.purdue.edu/pub, under the direction of Prof. Gene Spafford. Some can be found local to OSU on ftp://ftp.net.ohio-state.edu/pub/security.
