Attack detection in the Effnet firewall
2000 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

Denial of Service (DoS) attacks on the Internet occurs more and more often. The cost for the damage caused by a DoS attack can be million of dollars. If for example a popular Internet store is attacked, it may get unreachable by it's customers. This master thesis discusses one of the most well known DoS attacks, the SYN-flood attack. The main part of this thesis was to construct a SYN-flood attack detection and protection program for the Effnet firewall. This report describes the SYN-flood attack, some general solutions to it, and the, by the author written SYN-flood detection and prevention program. Simulations and test results show that the program is very effective to most types of SYN-flood attacks. To combine the SYN-flood protection with the Effnet firewall, an Attack Detection System was designed and implemented. This system will take care of the attack detection and prevention handling in the Effnet firewall. This system is also briefly described in this paper. Much work has been made holding the use of resources for the system at a minimum.
