Chapter 11. Maintenance and Security

A couple of truisms that can be said about computer systems are: "All systems will fail at some point of time" and "The most secure computer is powered off, not plugged into anything, and is in a vault." As systems administrators it is our job to mitigate risk to the best of our ability and within budgetary constraints. In this chapter, we will explore the following system maintenance tasks and steps that can be taken to keep the phone system secure:
