What is the position of IDS in the network security system?

In a network security system, an Intrusion Detection System (IDS) plays a critical role as a monitoring and analysis tool. It detects suspicious activities or policy violations by inspecting network traffic or system logs. Unlike a firewall that actively blocks threats, an IDS passively identifies potential intrusions and alerts administrators for further action.

IDS can be categorized into two main types:

  1. Network-based IDS (NIDS): Monitors network traffic for suspicious patterns, such as port scans or malware signatures. Example: Deploying an NIDS at the network perimeter to detect external attacks.
  2. Host-based IDS (HIDS): Focuses on individual devices by analyzing system logs, file changes, or process behavior. Example: Installing HIDS on a server to detect unauthorized file modifications.

For enhanced threat detection and response, Tencent Cloud offers Host Security (CWP) and Network Intrusion Detection (NIDS) services. These solutions integrate with IDS capabilities to provide real-time alerts, vulnerability scanning, and automated mitigation, helping businesses safeguard their infrastructure.
