<jats:p>The most serious appearance of modern malware is Botnet. Botnet is a fast growing problem that is still not well understood and studied. One widely spreading variant of the botnet attacks is an IRC botnet. There are a number of techniques to detect botnet attacks and infections, but they do not have the functionality to prevent malicious botnet activity. The development of a quality equipment to detect and remove botnet infection needs a good simulation environment that is safe and fully meets the functionality of botnet DoS attacks. The paper presents the features of the implementation of network simulator for DoS attacks. The simulator allows creating different attacks with various parameters. Some performance experiences are performed and the obtained results are shown.</jats:p>
