Secure VoIP architecture based on honeypot technology

VoIP or Telephony systems are increasingly replacing PSTN infrastructures for its easy management and low cost. While moving telephony to the public IP platform broadens its service capabilities, some security problems may occur because the amount of threats existing in IP networks and also the implementation weaknesses of IP based telephony systems. In this paper for evolving effective countermeasures for this ample array of attacks and providing available, reliable and qualitics VoIP services to users, a secure architecture was proposed by deploying honeypot idea. A honeypot is an information system resource. It intentionally put in harm's way to be compromised by attackers. If deployed in relevant location, it interacts just like real systems and obtains valuable information from attacker activities. We aim to protect VoIP infrastructure from different types of attacks after analyzing and evaluating this captured data favor other defense systems.
