PhD project description
The transmission of voice over packet switched networks is one of the most important emergent technologies in today's telecommunication world. Voice over IP (VoIP) ensures cost reduction, ease of management and simplicity of deployment but it introduces many security risks. The objectives of my thesis are:
- Threats identification and classification
- Studying the employed defense mechanisms at present and the proposed approaches in research and industry communities.
- Providing conceptual approaches to intrusion detection, reconnaissance, attack analysis, and security event correlation in a VoIP context.
- Developing a practical intrusion detection approach and implement it in a VoIP test bed within realistic conditions to be verified, corrected and validated.
Until now, we have proposed an IDS that analyzes the traffic of the SIP protocol basing on a Bayes model. Also, we have proposed a specified VoIP honeypot design and a security event correlation architecture dealing with heterogeneous VoIP agents and protocols.
