How does it fit into your security plan?
As a network security expert you should know you cannot just rely on one or a few tools to secure your network. You need to have a defense in depth mindset and layer your network defenses.
Through the use of inside and outside firewalls, DMZs, Routers and Switches, an IDS is a great addition to your security plan.
You can use them to identify vulnerabilities and weaknesses in your perimeter protection devices, such as: firewalls, switches and routers. The firewall rules and router access control lists can be verified regularly for compliance.
You can use IDSes to enforce security policies, such as: unauthorized Internet access, downloads of executable files, use of file sharing programs like Kazza, or Instant Messenger use.
IDSes are also an invaluable source of evidence. Logs from an IDS can become an important part of computer forensics and incident handling efforts.
