Intrusion Prevention System (IPS)

What Is Intrusion Prevention System (IPS)?

An Intrusion Prevention System (IPS) is a type of security system that monitors and detects malicious activity on a network. It is designed to detect and prevent malicious activity before it can cause damage or disruption to the network or systems it is protecting.

Description

An IPS works by monitoring network traffic and comparing it against a database of known attack signatures. When it detects malicious activity, it can take action to prevent the attack, such as blocking the traffic or alerting the security team. An IPS can detect and prevent a wide range of attacks, including phishing attacks, malware, and denial-of-service attacks.

Usage and Examples

An IPS is typically used in conjunction with other security measures, such as firewalls and intrusion detection systems, to provide a comprehensive security solution. Examples of IPS products include Cisco Firepower, Palo Alto Networks, and Check Point.
