ISS moves into VoIP security

Internet Security Systems (ISS) has moved into the VoIP intrusion prevention space with the launch of its Proventia Network Intrusion Prevention appliance.

ISS Australia MD Kim Duffy said enterprises wishing to implement VoIP technology needed to understand that the technology was susceptible to traditional Internet threats like viruses, worms and denial of service attacks.

“Given the rate of adoption of this technology within Australia, management executives need to seriously consider the security implications of introducing a VoIP solution to their network and plan for this accordingly,” he said.

Contrary to industry belief, not all network security products were detrimental to VoIP voice quality, availability and reliability of the connection, ISS claimed.

In an effort to prove its VoIP security credentials, the company hired Cybertrust division, ICSA Labs, to test the new product offering.

ICSA Labs, VP George Japak said that when designed effectively, security solutions could work within a large enterprise without compromising business-critical traffic and applications.

ISS said the Proventia Network Intrusion Prevention appliance provided protection for all VoIP protocols and was able to support thousands of concurrent calls.

Protocols included: H.323, H.225, Session Initiation Protocol (SIP),
Simple Traversal of User Datagram Protocol (UDP), through Network Address Translators (NATs)–(STUN), Q.931, H.245, T.120.
