Reading, UK – 23 May, 2007 – Stonesoft Corporation, an innovative provider of integrated network security and business continuity solutions, introduces StoneGate™ IPS 4.0 for intrusion prevention and detection. StoneGate IPS offers protection against denial of service (DoS) attacks, intranet protection with Windows network protocol analysis and VoIP traffic security with Session Initiation protocol (SIP) protocol inspection. StoneGate IPS forms the basis of layered defense for enterprise customers.

“There are basically two different types of denial of service attacks; illegal input and network traffic flood attacks, explains Klaus Majewski, Product Marketing Manager at Stonesoft. “In the first case, specially crafted packets cause the target service to crash, hang or reboot. The second type are resource consumption attacks that try to either tie up all the resources of the target machine or to fill the network bandwidth with traffic flood, restricting legitimate users’ access to the target server. StoneGate IPS protects servers against both kinds of denial of service attacks and allows business flow without interruption.”

StoneGate IPS protects networks

StoneGate IPS protects vulnerable applications and operating systems from network attacks. IPS performs network traffic normalisation, protocol analysis and deep inspection - identifying and dropping malicious packets. Network traffic flood attacks are prevented by identifying legitimate traffic sources from spoofed ones and allowing only valid client connections.

StoneGate IPS provides efficient protection for intranet services and inspection for commonly used Windows network protocols. When StoneGate IPS is used to segment internal networks to separate security zones, attackers or worms cannot roam freely inside the company's internal networks even if they have managed to breach the perimeter security. Stonesoft always advises organisations to have more than just one layer of protection around their business data and network.

StoneGate protects VoIP communications

Voice over IP (VoIP) is becoming a more and more viable means of lowering businesses’ call costs. StoneGate provides deep inspection for the SIP protocol that is used in VoIP traffic. Protecting the SIP communication prevents attackers from exploiting the protocol to breach internal networks.

Furthermore, StoneGate IPS 4.0 is capable of detecting and blocking attacks that use the new evasion technique reported by CERT Coordination Center on 15 May 2007.

StoneGate IPS and IDS

The StoneGate™ secure connectivity solution includes a Firewall and an Intrusion Prevention System (IPS). The StoneGate IPS, comprising of an IDS (Intrusion Detection System) and an IPS, defends the network proactively by detecting malicious packets within regular network traffic and blocking them before any damage occurs. Implementing StoneGate IPS expands the defence further within networks enabling comprehensive, multi-dimensional network security. StoneGate Firewall and IPS work together to provide intelligent defence throughout the enterprise network.

StoneGate IPS 4.0 is currently available for shipping.
