This Research to Practice Full Paper presents a new methodology in cybersecurity education. In the context of the cybersecurity profession, the `isolation problem' refers to the observed isolation of different knowledge units, as well as the isolation of technical and business perspectives. Due to limitations in existing cybersecurity education, professionals entering the field are often trapped in microscopic perspectives, and struggle to extend their findings to grasp the big picture in a target network scenario. Guided by a previous developed and published framework named “cross-layer situation knowledge reference model” (SKRM), which delivers comprehensive level big picture situation awareness, our new methodology targets at developing suites of teaching modules to address the above issues. The modules, featuring interactive hands-on labs that emulate real-world multiple-step attacks, will help students form a knowledge network instead of isolated conceptual knowledge units. Students will not just be required to leverage various techniques/tools to analyze breakpoints and complete individual modules; they will be required to connect logically the outputs of these techniques/tools to infer the ground truth and gain big picture awareness of the cyber situation. The modules will be able to be used separately or as a whole in a typical network security course.

Advance persistent threat is a primary security concerns to the big organizations and its technical infrastructure, from cyber criminals seeking personal and financial information to state sponsored attacks designed to disrupt, compromising infrastructure, sidestepping security efforts thus causing serious damage to organizations. A skilled cybercriminal using multiple attack vectors and entry points navigates around the defenses, evading IDS/Firewall detection and breaching the network in no time. To understand the big picture, this paper analyses an approach to advanced persistent threat by doing the same things the bad guys do on a network setup. We will walk through various steps from foot-printing and reconnaissance, scanning networks, gaining access, maintaining access to finally clearing tracks, as in a real world attack. We will walk through different attack tools and exploits used in each phase and comparative study on their effectiveness, along with explaining their attack vectors and its countermeasures. We will conclude the paper by explaining the factors which actually qualify to be an Advance Persistent Threat.
