Carrier VoIP Security Architecture

Inhalt:
This document describes a Security Architecture for Real-time Services over IP (RSoIP) Architecture. The architecture described here is used to protect AT&T’s VoIP infrastructure, hence our liberal use of AT&T VoIP architecture in describing the proposed security architecture. Our VoIP Security architecture describes guidelines and mechanisms designed to safeguard customer data, our VoIP network infrastructure, and voice and multimedia services and applications against internal and external threats including Denial-of-Service (DoS) and Distributed DoS (DDoS) attacks. Our VoIP Security architecture is designed to ensure availability, confidentiality, privacy, and integrity of user information.
