Hi All,

Our internal network is protected by 2 layers of firewall and we also use TippingPoint and Snort.  Is there any reason why we would need to implement a host-based intrusion detection system on the individual servers?  Any resources supporting this would be appreciated.

Well if your HIDS doesn't take any action, it's just another IDS making noise. Some HIDS take action, others only alert, most NIDS's are alert only and take no active actions, but an IPS or Application Firewall typically attempt to close, block or reset connections that trigger alerts.

HIDS have a completely different signature set and of course vary from vendor to vendor.  They report changes to the file system, processes that misbehave, attempts to access or modify protected resources, changes to auditing policy, etc that match signatures.  None of this activity is visible to a NIDS.  If an exposure occurs over an encrypted session (e.g. SSL), your NIDS will not see it but depending on what the exposure attempts to do on the box, your HIDS may detect it.

In addition, some government organizations require HIDS to be installed.  Check your network security compliance requirements

HIDS will help you in the event of an HTTPS, endpoint to endpoint encrypted attack. That type of attack will generally go through IPS's because of the private key encryption.
