Unified Communications solutions unify voice, video, data, and mobile applications on fixed and
mobile networks, enabling easy collaboration every time, from any workspace.
Overview
Cisco Unified Communications products can help businesses of all sizes streamline operations, increase employee
productivity, optimize communications, and enhance customer care. Because protecting a unified-communications-
based network from attacks is crucial to maintaining business continuity and integrity, Cisco has built security
features into its unified communications products, and augments them with the Cisco ASA 5500 Series Adaptive
Security Appliances.
Cisco ASA 5500 Series Adaptive Security Appliances are ideal for small businesses, branch offices, enterprises, and
mission-critical data center environments. These multifunction appliances deliver market-leading voice and video
security services for unified communications, including robust firewall, full-featured IP Security (IPsec) and Secure
Sockets Layer (SSL) VPN, intrusion prevention, and content security features. For unified communications
deployments, these platforms can protect up to 30,000 phones and deliver application inspection for a broad range
of unified communications protocols, including Skinny Client Control Protocol (SCCP), Session Initiation Protocol
(SIP), H.323, Media Gateway Control Protocol (MGCP), Computer Telephony Interface Quick Buffer Encoding
(CTIQBE), Real-Time Transport Protocol (RTP), and Real-Time Transport Control Protocol (RTCP).
Cisco ASA 5500 Series Unified Communications Features
Cisco ASA 5500 Series Adaptive Security Appliances are designed to secure real-time unified communications
applications such as voice and video. These appliances protect all of the critical elements of your unified
communications deployment (network infrastructure, call-control platforms, IP endpoints, and unified
communications applications). They deliver several security features that complement the embedded security within
the unified communications system, providing additional layers of protection. These features include:
●
Access control: Dynamic and granular policy access control prevents unauthorized access to unified
communications services.
●
Threat prevention: Built-in threat prevention protects the unified communications infrastructure from attempts
to exploit the system.
●
Network security policy enforcement: Effective unified communications policies for applications and users are
created and administered.
●
Voice encryption services: Cisco Transport Layer Security (TLS) proxy can help customers maintain their
security policies while encrypting signaling and media.
●
Perimeter security services for unified communications: In addition to SSL and IPsec VPN services, phone
proxy, mobility proxy, and presence federation, security services allow businesses to securely extend
communications services to remote users, mobile solutions, and business-to-business collaboration.
Access Control
Access control is a basic security function that allows only authorized access to resources and services within a
system. In a unified communications context, this control is often related to providing network-layer access control to
the Cisco Unified Communications Manager and other application servers as a first line of defense against attack.
