* Enterasys unveils a security system for enterprise VoIP networks
Enterasys Networks this week unveiled a security system for enterprise VoIP networks.
In his story detailing the announcement, Network World Managing Editor Jim Duffy explains that Enterasys Secure Open Convergence is a system comprising the vendor’s security software applications and its switching, routing and wireless infrastructure products. The overall purpose of the package is to detect and respond to security threats against the IP telephony infrastructure, enforce network access-control policies, and comply with regulations such as CALEA and E911.
At the center of the security software package are the Enterasys Sentinel NAC and Dragon Intrusion Prevention products that Enterasys says work in conjunction to detect unauthorized use of VoIP systems, prevent service disruption and eavesdropping, and monitor voice networks for new threats. The Dragon IPS is suited for VoIP environments because the company says it offers both signature and protocol behavioral analysis for H.323 and SIP VoIP protocols. The Enterasys Sentinel NAC software assesses, authenticates and authorizes VoIP users and telephony devices before allowing them onto the network, and enforces role-based policies after they are connected.
On the hardware side of this equation, Duffy explains that Enterasys’s switches, routers and wireless connectivity devices also have embedded policy-based security features on every interface. Specifically, the company’s Matrix switches are able to separately secure and prioritize a phone, camera, printer and computer all connected to a single network port, and provide flow-based visibility over individual voice, video and data conversations, according to the New Hampshire-based company’s claims.
