IPS is a network security solution that actively monitors and analyzes network or system activities to detect and prevent potential security threats or malicious activities in real-time.
Unlike IDS, IPS identifies hostile activity and traffic in systems using methods including signature-based detection, anomaly detection, and behavior-based detection. An IDS can only produce alerts; in contrast, an IPS can stop or prevent any harmful behavior that it finds.
To offer complete protection against cyber threats, and denial-of-service (DoS) attacks an IPS is set to cooperate with other network security technologies like firewalls and antivirus programs.
Network-based IPSs (NIPSs) and host-based IPSs (HIPSs) are the two primary categories of IPSs. While HIPSs are installed on individual machines or hosts and watch system activity for indications of malicious behavior, NIPSs are placed at network borders and monitor network traffic in real-time.
IPS is vital as it can actively prevent and block attacks, and lowers the risk of data breaches and other cyber dangers, making it a crucial part of network security.
