HELSINKI, Finland – 16 May, 2007 – Stonesoft Corporation, an
innovative provider of integrated network security and business continuity solutions, announces
that the new StoneGate IPS versions 4.0 and later are capable of detecting and blocking attacks
that use the new evasion technique reported by CERT Coordination Center (CERT/CC).
According to the CERT/CC vulnerability note published on 15 May 2007, the new evasion
technique is used for bypassing intrusion detection/prevention systems that scan HTTP traffic. The
attacker can bypass security controls of an IDS/IPS using encoded data with HTTP POST method. If
the IDS/IPS does not decode Fullwidth Unicode encoded HTTP POST request data, an attack will not be
detected and can cause damage within the web server.
“The new StoneGate IPS contains pretty effective normalization for HTTP client requests”,
says
Mika Rautila, Chief Technology Officer of Stonesoft. “IPS
allows protecting corporate networks fast and without downtime. Bringing down business-critical
services for maintenance means lost revenue, but with StoneGate IPS, security vulnerabilities can
be patched without the need for unscheduled maintenance breaks.”
The StoneGate™ secure connectivity solution comprises of a Firewall and an Intrusion
Prevention System (IPS). The StoneGate IPS, comprising of an IDS (Intrusion Detection System) and
an IPS (Intrusion Prevention System), 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 all over
the enterprise network.
