This memo describes security threats for the larger (intra-domain or
inter-domain) multicast routing infrastructures.  Only Protocol
Independent Multicast - Sparse Mode (PIM-SM) is analyzed, in its
three main operational modes: the traditional Any-Source Multicast
(ASM) model, the source-specific multicast (SSM) model, and the ASM
model enhanced by the Embedded Rendezvous Point (Embedded-RP)
group-to-RP mapping mechanism.  This memo also describes enhancements
to the protocol operations that mitigate the identified threats.  This 
memo provides information for the Internet community.

This document is a product of the MBONE Deployment
Working Group of the IETF.
