The intrusion prevention system provides a secure way for communication as well as makes sure that the system is threat-free. It will inspect the system threats that try to infect the system and handle them accordingly by blocking or terminating them. Some techniques are used by the IPS to protect the system from unnecessary activities, these are signature-based, anomaly-based, and policy-based. Signature-based prevention is used to identify the regenerated threats or the threats that have been already detected in the system. Anomaly-based prevention will inspect unethical activities that are trying to get access to the system. Policy-based prevention will work on the rules that have been defined and managed by the administrator. As it identifies some unethical event during the transmission of data then it will take the corresponding action against the threat. Some intrusion prevention systems are being used which are as follows.
Network Intrusion Prevention System:
It will inspect the network and control the overall activities that have been taking place. It will follow the network traffic and scan the data transactions. If any threat occurs during the transmission the network intrusion prevention will secure the whole network system.
Host Intrusion Prevention System:
It will provide security to the single host and manage to protect it. It will handle the host system inspect malicious activities, and scan the system to protect the host system.
Network Behavior Analysis:
It will manage the network behavior and all the activities that have been taking place between the networks. During scanning, if the intrusion prevention system finds out the malicious information then it will block or terminate that threat. It will make sure that no intruder will get access to the internal network.
Wireless Intrusion Prevention System:
This will provide security to the wireless network. It will scan the wireless network system to find out unauthorized access and block unauthorized devices that are trying to get into the network.
