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.
