Denial of Service Attack Generator in Apache JMeter

Cyber attacks are currently a major threat to individuals as well as businesses or institutions. Denial of service (DoS) attacks are very common cyber attacks that focuses on availability of network services or network devices. This paper deals with developing of new modules of DoS attacks and network traffic generator into Apache JMeter that is designed to load test functional behavior and measure performance. Modules developed together with Appache JMeter tool can test a network infrastructure and find weak localities prone to DoS cyber attacks. One goal of this paper is to compare tools for stress testing of web servers and services. The network generator module of DoS attacks allows stress testing of networks based on the Transmission Control Protocol/Internet Protocol (TCP/.IP). With using the generator developed it is possible to test the availability of network devices when exposure to DoS attacks. Selected cyber attacks targeting on the availability of network resources (DoS attacks) that can test a resistance of a network infrastructure are described in the article. DoS attacks described have been implemented in the Apache JMeter tool together with the design and the development of the network generator of DoS attacks. New modules can be used to test a resistance of network infrastructure. Finally, the measured values using the generator developed are presented and discussed.
