This component popularly known as Intrusion Detection Systems or IDS is often complimented by a component (Intrusion Prevention System or IPS ) that takes firewalling decisions based on inferences drawn from the IDS alerts. The Intrusion Prevention System or IPS helps to protect the resources before an attack effects and network administrator acts out.
