White Paper Abstract:
Many organizations have discovered that unified communications-the convergence of data, and video onto a single network infrastructure-can enhance employee productivity and ty, while dramatically reducing communications costs. What is crucial to attaining these ages is securing unified communications systems to maintain service availability and integrity. To increase protection, Cisco® recommends an approach in which multiple layers urity are integrated throughout Cisco Unified Communications applications and systems. The rimary components of a unified communications system include the endpoints; call control; ations; and, perhaps most critically, the converged IP network infrastructure. Cisco routerbased security solutions provide a solid foundation toward building a secure unified communications architecture that can secure each of these four critical components. Cisco IOS® Firewall provides perimeter security and policy control to maintain the integrity and availability of unified communications components.
