Detection of overload and protection from denial of service attacks is a common problem
in information system servers. Such situation may be the result of simple overload,
such as increased service request rate during peak hours, or a malicious distributed
attack originating from many computers. This article describes a solution to this
problem, focusing on protection mechanisms against both natural and malicious overload,
based on analysing the queue of requests – which, as described in this paper, is chosen
to be unlimited.
Furthermore, detection and protection scheme against blocking and crash-bug exploiting
attacks is presented.
