There are different types of systems or the programs are designed for the monitoring of different types of work of the computer systems or many other devices related to the same pattern. So, another system whose name is intrusion detection system is used in the field of computer networking for the sake of the monitoring of different components of the networks and checks the possibilities of infection of the system and maintenance of the policy of management also.
Characteristics of Intrusion Detection System:
There are several characteristics of the intrusion detection system that governs the specification and the networking of the system in the protection of the computer networking. Some of the important characters are as follows.
- A true intrusion detection system can be able to mange the security measures and can also mange all the events of the administration.
- Many forms pf intrusion detection system can detect the problem and can stop them at the spot and restrict it from succeeding.
- Intrusion detection system also has property to that they can change the settings of the windows firewall according to this work and prevent the system from dangerous attacks.
How Intrusion Detection system Works?
The working of the intrusion detection system is quite similar as that of the other programs used to prevent the computer system from dangerous threats like malware, spyware, spam and many more. The job of the intrusion detection system starts from the recording the information about the problem and check the occurrence and the nature of the threat. When the system monitors the problem and collects the data about it, then it sends this information to the administration department of the intrusion detection system which makes several preventive measures to protect the system and keep the system in the safe hands. Intrusion detection system can work in the specific manner by monitoring some important things. These important things are as follows.
- Monitoring the activity of the network and activity of the threat in the network.
- This system has ability to detect the viruses, malware, spyware and different form of viruses and the important thing about this it can also locate their restore point.
- Intrusion detection system can work by observing the unauthenticated and unauthorized use of different programs of networking.
So, the whole working of the intrusion detection system based on the examination of such events of networking.
Types of Intrusion Detection System:
Intrusion detection system can also categorized into different types if but the important one are given below.
Network Intrusion Detection System:
Independent systems that monitor the network traffic and different applications of networking such as sniffing and check them either they are free from threat or not with the help of sensors are called as network intrusion detection system. Common example is Snort.
Host-Based Intrusion Detection System:
Another important type of intrusion detection system that consist of a special agent on the host that observes the different activities such as calls of system, file logging and many other application of relevant field and can protect the from other host also is called as host based intrusion detection system.
Premier Intrusion Detection System:
This type of intrusion detection system can be able to identify the locations or the restore points of the malicious software that can affect the system of infrastructure. It also detects the change in the premier border.
VM based Intrusion Detection System:
A type of system that can involve in the observations of the virtual memory of the computer system can check the virus is referred to as the VM based intrusion detection system. This process of observation is also called as the Virtual monitoring.
