20.4 IPS Technical Reference
This section contains some background information on IPS.
Host Intrusions
The goal of host-based intrusions is to infiltrate files on an individual computer or server in with the goal of
accessing confidential information or destroying information on a computer.
You must install a host IPS directly on the system being protected. It works closely with the operating
system, monitoring and intercepting system calls to the kernel or APIs in order to prevent attacks as well
as log them.
Disadvantages of host IPSs are that you have to install them on each device (that you want to protect)
in your network and due to the necessarily tight integration with the host operating system, future
operating system upgrades could cause problems.
