Transparent Optical Networks (TONs) can communicate large amount of data at a high speed among nodes of the network. So, any type of failure whether caused by component failure or caused by an attack can cause a significant loss of data. In case of faults, the network can restore its functionality, by identifying the malfunctioning component of the network and solving the problem. This is not the case with a deliberate, malicious attack. That is why security and attack management is becoming a very important issue in WDM networks. In the previous years, a number of researchers worked on solving the attack problem. One common approach is to plan the network in a way that minimizes the influence of an attack, by using appropriate routing and wavelength assignment (RWA) strategies. Most of the research in this area focuses on the static traffic model, where the set of traffic demands is known in advance. In this thesis, we propose a new security-aware RWA technique for dynamic traffic, using dedicated path protection. The goal is to improve the performance of WDM networks by accommodating more traffic demands, while reducing the probability of disruption due to malicious attacks.
