●

Protection of call-control servers: By controlling access from clients to these servers, the Cisco ASA 5500

Series can prevent malicious or unauthorized network connections that could affect performance or

availability. By statefully inspecting the connections to ascertain that they meet the access-control policy and

that the connection conforms to expected behavior, the Cisco ASA platform provides a first line of defense for

a secure unified communications deployment.

●

Remote-access security: The Cisco ASA 5500 Series delivers SSL and IPsec VPN, phone proxy, mobility

proxy, and presence federation security services to secure teleworker phones, Cisco Unified IP Phones, and

third-party phones such as Apple iPhones, mobile phones, and business-to-business federation deployments.

●

SIP trunk security: Businesses are migrating to SIP trunk architectures to lower their communication costs.

The robust SIP security capabilities of the Cisco ASA 5500 Series provide protection from any attacks

through SIP trunks.

●

Trusted and untrusted boundaries: You can position the Cisco ASA 5500 Series as a security device between

a trusted and untrusted network to help ensure that vulnerabilities from the untrusted network do not affect

the trusted network. You can use a Cisco ASA 5500 Series appliance to proxy traffic, or to secure an internal

network against external access in a DMZ architecture.

With the range of Cisco ASA 5500 Series models available, your organization has the flexibility to standardize on a

single family of security products while positioning specific models to meet different performance needs for every

topology or location.
