摘要: Convergence in networks and applications enables carrying voice, video, other data on the same IP-based infrastructure, provides various services related to these kinds of a unified way. Such scheme benefits businesses substantially considering lesser cost building managing single network infrastructure instead two separate ones. However, poses serious threats security solutions general, intrusion detection systems (IDSs) particular. Inherited flaws vulnerabilities TCP/IP protocols at lower layers make voice susceptible risks it has never been subjected before public switched telephone (PSTNs). Signaling delivery application layer have their weaknesses too which breaching confidentiality integrity relatively easy. In this paper, we present design implementation hybrid, host-based system that is suitable for converged environments. Our unique terms providing an efficient combination specification-based signature-based techniques. Specification-based modules provide solid awareness semantics as well syntax involved. solution goes beyond addressing issues address transport The feasibility our proven through excellent accuracy reasonable performance evaluation figures get from experiment.
