Denial of Service Attacks and SIP Infrastructure: Attack Scenarios and Prevention Mechanisms

Tags:
industry standard protocols

Overview This paper addresses the issue of Denial of Service (DoS) attacks targeting the hardware and software of voice over IP servers or by misusing specific signaling protocol features. As a signaling protocol the paper investigates here the Session Initiation Protocol (SIP). In this context the paper mainly identifies attacks based on exhaustion of the memory of VoIP servers, attacks on the CPU or by causing excessive communication with external servers such as DNS or authentication servers. The paper addresses two kinds of attacks: wanted attacks caused by malicious users and unwanted attacks caused by network mis-configurations, broken implementations or any other unknowledgeable technology use.
