Intrusion Detection System

An Intrusion Detection System (IDS) is a security solution that monitors network traffic for signs of suspicious activity, cyberattacks, or policy violations. The goal of an IDS is to detect potential threats early, allowing for a quick response to prevent damage or breaches.

How an IDS Works

• Monitoring Traffic: The IDS analyzes network traffic in real-time, looking for patterns that may indicate malicious behavior.
• Signature-Based Detection: This method compares network activity against a database of known attack signatures.
• Anomaly-Based Detection: The IDS also identifies unusual behavior that deviates from normal network patterns, even if it doesn’t match known signatures.

Types of IDS

• Network-based IDS (NIDS): Monitors the entire network and looks for malicious activity within the data packets.
• Host-based IDS (HIDS): Monitors individual devices or hosts, checking system logs and configurations for suspicious behavior.

The Benefits of IDS

• Early Threat Detection: IDS provides early warning of potential security threats, allowing for rapid response and mitigation.
• Real-time Monitoring: Continuous monitoring ensures that threats are detected as soon as they occur.
