Abstract:

The low-rate DoS attacks are presented as a novel approach for carrying out a denial of service (DoS) attack against servers. Although this kind of attacks are carried out by sending attack packets to the victim, it gets advantage of some vulnerabilities in the servers in order to reduce the amount of tra±c needed for achieving its purposes. The ¯nal result is the use of a low-rate tra±c against the victim, which potentially could allow the attack to bypass intrusion detection systems monitoring high rate tra±cs. In this work, the fundamentals of the attack are presented, dealing with both iterative and concurrent servers. Besides, an analysis of its design and the evaluation of the performance of the attack is contributed. For this purpose, a mathematical framework is developed and besides, the di®erent results are contrasted in both simulated and real environments.
