7 Ways to Get the Most from Your IDS/IPS

Intrusion detection and prevention is at the foundation of successful security in-depth. Securing the perimeter requires a solid understanding of these two critical components.

IDS, IPS, or Both?
Once you decide that you need to deploy one of these systems, the first question is whether you need to deploy an IDS, an IPS, or both. 'Both' is a very real possibility since the two do very different things.
An IDS is a monitoring system. That's all. In most cases, an IDS will issue an alert to be read by an analyst who then takes action. In some cases, an IDS will be integrated with a firewall, filter, or other security appliance that can take action based on an IDS alert. The important point to remember is that an IDS is not in-line with the network, so it has no direct mechanism for stopping packets. The IDS connects to the network through a span port or network tap that provides data without disrupting the regular flow of network traffic.
The IPS, on the other hand, is like a firewall in that it is in-line for network traffic - traffic flows through the IPS. This means an IPS can take direct, immediate action when it detects a triggering condition.
Many organizations choose to deploy both an IPS and an IDS. For these organizations, the IPS is part of the active network security, while the IDS gives analysts an in-depth look at the traffic flowing across the network.
