Chapter 12. Filesystem Integrity

Integrity is one of three commonly used principles of computer security; confidentiality and availability are the other two. In the purest sense of the three principles, integrity simply refers to the means by which you ensure that data is authentic and has not been altered or tampered with in any way. One aspect of ensuring data integrity is ensuring the integrity of the system on which the data is housed.

This chapter looks at some very specific means you have at your disposal when running Linux to ensure data integrity. These include examining the files on a Linux system to make sure that they haven't been altered without your knowledge, and they include looking for anomalies that may indicate the presence of an intruder on the system.
