MAFIA: A multicast management solution for access control and traffic filtering

Abstract

Recently, multicast has seen only marginal wide-scale deployment. One of the main reasons is the lack of support for security and traffic management. Although there has been some recent work, these efforts have not emphasized the critical need to deploy security features side-by-side with management solutions. In this paper, we propose MAFIA, a multicast management solution with the specific aim of strengthening multicast security through multicast access control, multicast traffic filtering, and the prevention of DoS attacks. MAFIA achieves these tasks by making use of information about multicast group memberships available at different locations in a network. We have also designed various deployment solutions for MAFIA. We have implemented one such solution using the GNU/Linux operating system. © IFIP International Federation for Information Processing 2003.
