TLDR:
- An IDS and IPS is a security solution designed to detect and prevent unauthorized access and malicious activity in computer systems and networks.
- IDS and IPS solutions can be software- or hardware-based and typically include sensors, analyzers, and user interfaces.
An Intrusion Detection and Prevention System (IDPS) is a security solution designed to detect and prevent unauthorized access, misuse, and modification of computer systems and networks. An IDPS monitors network traffic and system activity in real-time, analyzing events and alerting security administrators when potentially malicious activity is detected. The system can detect threats including malware, denial of service (DoS) attacks, and unauthorized access attempts. IDPSs can be signature- or behavior-based systems that operate in either detection or prevention mode.
Software-based IDS and IPS are applications that run on general-purpose computer hardware while hardware-based IDS and IPS are appliances purpose-built for network security. Many IDS and IPS solutions combine software and hardware components. The main difference between Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) is their function in responding to security threats. IDS primarily monitor network traffic for suspicious activity and generate alerts, while IPS actively block or mitigate detected threats, providing an additional layer of security.
Popular Intrusion Detection & Prevention Systems for 2024 include Cynet, Snort, BluVector Cortex, Check Point Quantum IPS, Cisco NGIPS, Fail2Ban, Fidelis Network, Hillstone Networks, Kismet, NSFOCUS, and many more. These systems offer advanced threat detection capabilities, real-time network monitoring, integrated threat intelligence feeds, customizable rules, and automated response actions to enhance network security.
