Signature-Based Multi-Layer Distributed Intrusion Detection System Using Mobile Agents
The Internet and computer networks are exposed to an increasing number of security threats. With new types of attacks appearing continually, developing flexible and adaptive security oriented approaches is a severe challenge. Intrusions Detection Systems (IDSs) are systems that try to detect attacks as they occur or after the attacks took place. IDSs collect network traffic information from some point on the network or computer system and then use this information to secure the network. In this context, signature-based network intrusion detection techniques are a valuable technology to protect target systems and networks against malicious activities. Signature-based detection is the most extensively used threat detection technique for (IDSs).
