Securing VANET by Preventing Attacker Node Using Watchdog and Bayesian Network Theory

Securing the Node of an Active Network

Active networks aim to provide a software framework that enables network applications to customize the processing of their communications. Security is of critical importance to the success of active networking. This paper discusses the design of securing the node of an active network using active networking principles. The secure node architecture includes an Active Node Operating System Securi...

Network risk management using attacker profiling

Risk management refers to the process of making decisions that minimize the effects of vulnerabilities on the network hosts. This can be a difficult task in the context of high-exploit probability and the difficult to identify new exploits and vulnerabilities. For many years, security engineers have performed risk analysis using economic models for the design and operation of risk-prone, techno...

Securing software systems by preventing information leaks

Learning Bayesian Network Structure Using Genetic Algorithm with Consideration of the Node Ordering via Principal Component Analysis

‎The most challenging task in dealing with Bayesian networks is learning their structure‎. ‎Two classical approaches are often used for learning Bayesian network structure;‎ ‎Constraint-Based method and Score-and-Search-Based one‎. ‎But neither the first nor the second one are completely satisfactory‎. ‎Therefore the heuristic search such as Genetic Alg...

Securing Cloud Data in the New Attacker Model

The world just witnessed the surge of a new and powerful attacker, which was able to coerce operators and acquire the necessary keys to break the privacy of users. Once the encryption key is exposed, the only viable measure to preserve data confidentiality is to limit the adversary’s access to the ciphertext. This may be achieved, for example, using multi-cloud storage systems. These systems sp...
