A New Dynamic Cyber Defense Framework

Current approaches in cyber defense are flawed as they are fortress-based and generally static in nature. They are not flexible in dealing with variations of attacks, especially zero-day attacks. To address this issue, researchers have looked into dynamic cyber defense. However, the available approaches are either only about high-level strategies or only about specific tactics. There is no integrated approach that brings both levels together in a systematic way. This research article intends to address this challenge by proposing a new dynamic cyber defense framework that is systematic and cohesive, and that integrates strategic, operational, and tactical levels. It improves the research in dynamic cyber defense by employing game-changing elements such as a contextual analysis system and an intelligent decision-making system.
