Bulusu, S. T., Laborde, R., Wazan, A. S., Barrere, F., Benzekri, A..  2017.  Describing Advanced Persistent Threats Using a Multi-Agent System Approach. 2017 1st Cyber Security in Networking Conference (CSNet). :1–3.

Advanced Persistent Threats are increasingly becoming one of the major concerns to many industries and organizations. Currently, there exists numerous articles and industrial reports describing various case studies of recent notable Advanced Persistent Threat attacks. However, these documents are expressed in natural language. This limits the efficient reusability of the threat intelligence information due to ambiguous nature of the natural language. In this article, we propose a model to formally represent Advanced Persistent Threats as multi-agent systems. Our model is inspired by the concepts of agent-oriented social modelling approaches, generally used for software security requirement analysis.

The TLS protocol is the primary technology used for securing web transactions. It is based on X.509 certificates that are used for binding the identity of web servers' owners to their public keys. Web browsers perform the validation of X.509 certificates on behalf of Web users. Our previous research in 2009 showed that the validation process of Web browsers is inconsistent and flawed. We showed how this situation might have a negative impact on Web users. From 2009 until now, many new X.509 related standards have been created or updated. In this paper, we performed an increased set of experiments over our 2009 study in order to highlight the improvements and/or regressions in Web browsers' behaviours.
