Clavister solutions stand against socks stress-denial-of-service attacks Hamburg, September 30, 2009 for a Denial-of-Service(DoS)-Attacke hacker need access to resources and bandwidth. The new and potentially devastating attack tool socks stress exploits a vulnerability in the TCP/IP Protocol, however, which significantly facilitates the work attackers. In a series of tests, the security gateways from Clavister, Swedish provider of IP-based security and unified threat Management(UTM)-Losungen, successfully against socks stress attacks prevailed and could effectively close the TCP security vulnerabilities caused by this tool. Often business-critical services no longer available after a successful DoS-attack. Many companies believe to be protected with its security solutions of DoS attacks.

But this is a false sense of security. The attack tool socks stress recently published exploits multiple TCP vulnerabilities in common operating systems, without requiring large resources. This makes them extremely dangerous socks stress. We had access to the socks stress tool for some time and let it compete in a series of tests against our security gateway”, explains Andreas asander, VP product management at Clavister. While we assumed that our security gateway products to achieve a high level of safety and behave very robust against DoS attacks. Nevertheless, we were curious to see how our solutions to socks stress attacks would claim. The more we are pleased that the TCP stack of our solutions withstood all attacks.” To protect network resources behind the security gateway against DoS attacks, Clavister recommends the use of SYN relayer or any other applicable ALG (http, FTP, etc.).
