IDPS - Intrusion Detection and Prevention System

Definition

What are Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS)?

Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) are security measures designed to protect networks and systems from unauthorized access or various attacks. They are often used in combination with each other and with other security measures, such as firewalls, to provide a comprehensive security solution.

IDS is a system that monitors network traffic to detect suspicious activity and alerts network administrators when such activity is detected. IDS can be host-based, meaning it is installed on a single computer or device, or network-based, meaning it monitors traffic across the network. IDS can use various methods to detect suspicious activity, including pattern matching, anomaly detection, and heuristics.

IPS is similar to IDS but takes a more proactive approach to security. While IDS merely alerts network administrators to suspicious activity, IPS can take action to prevent the activity from occurring. This can include blocking traffic from certain IP addresses, blocking ports, and more.
