Host-based intrusion prevention systems are another layer of defense. These tools limit the various applications running on your system, blocking their ability to interact with the underlying kernel. Some bots function, however, by installing themselves inside of other legitimate applications, using them to undermine the system and potentially fly below the radar screen of your host-based IPS.
Therefore, in addition to network- and host-based IPSes, you should also make sure you have thoroughly deployed antivirus, antispyware and host-based firewalls. By operating on all of these fronts, you can dramatically lower the threat posed by your environment's bots.
