Sipera Enhances VoIP Security for Cisco Unified Communications

Sipera Systems released a software upgrade for its line of Sipera IPCS VoIP/UC security appliances that enables enterprises to better protect VoIP networks and remote users when deploying Cisco-based unified communications. Among other new IPCS features, Sipera added further protection capabilities for the Cisco Skinny Call Control Protocol (SCCP) along with encryption (TLS and SRTP) and 2-factor authentication (RSA SecurID) support for Cisco 7941 and 7961 phones.

Key features of the Sipera IPCS upgrade include:

  • High availability with sub-second failover, even for encrypted media (SRTP), to ensure the service is always on and protected,

  • Proxy support for remote user phone configuration (TFTP) and phone
    services (HTTP), such as corporate directory and help information, to allow off-site configuration and authorization for remote users, and

  • VoIP VPN support, including encrypted signaling (TLS) and media (SRTP), on the IPCS 310 platform, allowing smaller enterprises to cost
    effectively adopt this security functionality, which was previously
    only available on the larger-scale IPCS 410 and 510 appliances.

The Sipera IPCS products offer unified communications (UC) threat prevention using a variety of sophisticated VoIP-specific security techniques including anomaly detection, protocol scrubbing, behavior learning and fingerprint verification.

Sipera said its appliances also incorporate UC policy compliance functionality, which enforces granular security polices to all UC traffic, based on user, device, network and time of day, and ensures secure UC access, to guarantee the privacy and authentication of all UC traffic to the enterprise and handle session border control issues, such as firewall/NAT traversal, in a single security device.
