Abstract
This work focuses onto proposal and implementation of modification of SYN flood (DoS) attack detection algorithm. Based on Counting Bloom filter, the attack detection algorithm is proposed and implemented into KaTaLyzer network traffic monitoring tool. TCP attacks can be detected and network administrator can be notified in real-time about ongoing attack by using different notification methods.
