Chapter 7. Chroot Jails

In this chapter we will be looking at how ModSecurity can help us to create a chroot jail for Apache. A chroot jail is used to isolate a program from the rest of the file system. This is done so that if the program gets compromised (for example, if someone is able to exploit a hole in a web application to execute files with the privileges of the Apache server program) then the attacker will not be able to access the rest of the file system.
