Juniper Secures VOIPJuniper Secures VOIP

LOS ANGELES -- At the Internet Telephony Conference and Expo, Juniper Networks, Inc. (Nasdaq: JNPR) today announced its Dynamic Threat Mitigation solution that enables service providers to offer enterprise and residential customers enhanced security and assurance of network services, including voice-over-Internet-protocol (VoIP) communications. The solution encompasses Juniper routers and intrusion detection and prevention (IDP) systems with Juniper's service deployment system (SDX) software to prevent session initiated protocol (SIP) attacks, worms and denial-of-service attacks from impacting SIP-based voice communications and network services.

Businesses are turning to IP telephony to reduce costs by consolidating multiple services onto a single IP network, but this new medium is opening the door for additional security threats. SIP, the VoIP signaling protocol, can act as the mechanism to launch attacks against SIP servers, soft phones or other network devices and endpoints. A SIP denial of service attack can occur when a flood of INVITEs to the SIP server overwhelms it, limiting or completely stopping the ability to respond to legitimate requests. This could ultimately bring down the entire VoIP network. Juniper Networks' Dynamic Threat Mitigation solution protects against these attacks by allowing service providers to identify the attack on a per user or per-application basis. The attack can then be prevented quickly and effectively using a combination of policy enforcement, dynamic policy control and intrusion detection and prevention techniques.

"With more services being pushed across the IP network, it is essential to also maintain increased levels of security and control to ensure services delivered to the enterprise or residential customer are not compromised," said Scott Heinlein, senior marketing manager of voice solutions for Juniper Networks. "Juniper's combined use of intrusion detection and prevention with our service deployment system is a natural and very useful progression that provides threat protection to the edge without disrupting the customer."
