Network Intrusion Prevention System
Overview
The NIPS monitors the network for malicious activity or suspicious traffic by analyzing the protocol activity. Once the NIPS is installed in a network, it is used to create physical security zones. This, in turn, makes the network intelligent and quickly discerns good traffic from bad traffic. In other words, the NIPS becomes like a prison for hostile traffic such as Trojans, worms, viruses, and Polymorphic threats.
An intrusion prevention system (IPS) sits in-line on the network and monitors the traffic. When a suspicious event occurs, it takes action based on certain prescribed rules. An IPS is an active and real-time device unlike an intrusion detection system, which is not inline and is a passive device. IPSs are considered to be the evolution of the intrusion detection system.
Features and Benefits
Detects attacks based on specific patterns, such as network traffic, number of bytes, and known previous attacks
Systems use machine learning to create a model of trustful activity and compare the current activity with it
Relies on predetermined network traffic baselines and activity outside of that baseline is seen as a potential threat to the network; requires a systems administrator to configure security policies manually
