Abstract:
Computer networks are a critical factor for the performance of a
modern company. Managing networks is as important as managing any other
aspect of the company’s performance and security. There are many tools and
appliances for monitoring the traffic and analyzing the network flow security.
They use different approaches and rely on a variety of characteristics of the
network flows. Network researchers are still working on a common approach
for security baselining that might enable early watch alerts. This research
focuses on the network security models, particularly the Denial-of-Services
(DoS) attacks mitigation, based on a network flow analysis using the flows
measurements and the theory of Markov models. The content of the paper
comprises the essentials of the author’s doctoral thesis.
