What is Intrusion Detecting 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 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.
