these systems to internal threats, such as disgruntled employees,
compromised systems, or infected laptops. Internal threats can be more
severe than external threats for these critical infrastructure components. To
provide adequate service availability, VoIP and other multimedia systems
must be protected from internal threats.
The SMC 2450 is a security system that consists of a PC-based hardware
platform with SMC software.
As shown in Figure 3 on page 34 , the SMC 2450 creates a Secure Multimedia
Zone (SMZ) between the enterprise Local Area Network (LAN)/Wide Area
Network (WAN and the call servers. The SMZ protects the signaling and
media infrastructures of the MCS 5100 and CS 1000 product lines. All
signaling and media traffic entering or leaving the SMZ must pass through
the SMC.
