What Is the Intrusion Detection System (IDS)?

The intrusion detection system (IDS) can monitor the traffic on the network, search for suspicious activities and known threats through the system, and issue threat warnings when such items are discovered. The overall goal of IDS is to notify the IT department in times of unusual behavior that may be occurring in the system. The threat warning usually contains information about the source address of the intrusion, the target/victim address, and the type of suspicious attack. Enterprise IT departments can learn about potential malicious activities in their technical environment by deploying intrusion detection systems. Each IDS is programmed to analyze traffic and identify patterns. In this mode, IDS can identify traffic that may indicate various cyber attacks. In addition, intrusion detection systems can detect traffic that is problematic for specific software.

There are two types of Intrusion detection systems (IDS): host-based intrusion detection systems and network-based intrusion detection systems. The key to distinguishing between these two types is where the sensors of the intrusion detection software are placed (host/endpoint or network). In addition to the above classification methods, some experts even further subdivided the intrusion detection market, including boundary IDS, VM (virtual machine) -based IDS, stack-based IDS, signature-based IDS, and abnormal behavior-based IDS. Regardless of the type, the technology usually has the same function, that is, it is designed to detect intrusive behavior at the location of the sensor and timely feedback the abnormal behavior detected to the security analyst. IDS (as a system) has been replaced by IPS and next-generation firewalls. These tools adopt the concept of IDS and supplement it with many new functions and protection layers, including behavior analysis, web filtering, application identity management, and other control functions, etc.
