What Is an Intrusion Detection System and the Types of It [MiniTool Wiki]
For modern networked business environments, a high degree of security is required since it can ensure safe and reliable information communication between various organizations. After the failure of the traditional technology, the intrusion detection system can be used as a security protection technology suitable for system security.
Usually use security information and incident management systems to centrally report or collect any malicious activities or violations. If you want to learn more information about the intrusion detection system, you can continue to read this post from MiniTool .
What Is an Intrusion Detection System
What is an intrusion detection system? An intrusion detection system (IDS) is a device or software application that monitors the network for malicious activity or policy violations. In general, it uses security information and incident management systems to centrally report or collect any malicious activities or violations.

Types of IDS
Now, let’s see the types of intrusion detection systems. It can be divided into 5 types. The following are the details.
Network Intrusion Detection System (NIDS):
The network intrusion detection system (NIDS) is one of the types of IDS. NIDS is set up at a planned point within the network. How does it work in the network?
When placing an intrusion detection system on one or more strategic points in the network to monitor communication with all devices on the network, it will analyze the passed passing and match the passing passed on the subnet with the library of known attacks. Once the attack or abnormal behavior is detected, the administrator will receive an alert.
Host Intrusion Detection System (HIDS):
The second type is the host intrusion detection systems (HIDS). It is running on independent hosts or devices on the network. The incoming and outgoing packets from the device are monitored by HIDS. If suspicious or malicious activity is detected, the administrator will receive the alert. The existing system files will be snapshotted and will be compared with the previous snapshot.
If the analytical system files were edited or deleted, the administrator will receive an alert and he will investigate it. For example, the usage of HIDS in the network can be seen on mission-critical machines, which are not expected to change their layout.
Protocol-based Intrusion Detection System (PIDS):
The third one is the protocol-based intrusion detection system (PIDS). It includes a system or agent that will always be located in front of the server to control and interpret the agreement between the user/device and the server.
It is trying to regularly monitor the HTTPS protocol stream and accept the related HTTP protocol to secure the webserver. This system would need to reside in this interface, between to use the HTTPS because HTTPS is un-encrypted and before instantly entering its web presentation layer.
Application Protocol-based Intrusion Detection System (APIDS):
The fourth type is the application Protocol-based Intrusion Detection System (APIDS). It is a system or agent that generally resides within a group of servers. It monitors and interprets the communication on application-specific protocols to identify the intrusions.
For example, as it transacts with the database in the webserver, this would monitor the SQL protocol explicit to the middleware.
Hybrid Intrusion Detection System:
The last type is the hybrid intrusion detection system. It is made by the combination of two or more approaches to the intrusion detection system. The host agent or system data is combined with network information to develop a complete view of the network system in the hybrid intrusion detection system.
Compared to the other intrusion detection system, the hybrid intrusion detection system is more effective.
Here is all the information on the types of IDS.
