Visualizations can range from simple charts illustrating attack frequency to intricate network graphs depicting data flow and vulnerabilities.

Cyberattack Lifecycle Visualization

A typical cyberattack follows a distinct lifecycle. Visualizing this lifecycle helps researchers understand attack methodologies and develop effective countermeasures. Imagine a circular diagram, divided into several segments representing each stage. The first segment, Reconnaissance, depicts the attacker gathering information about the target. This could be represented by an icon of a magnifying glass over a computer.

The next segment, Weaponization, shows the attacker developing or acquiring malicious tools. This might be visualized as a syringe injecting code into a computer. The third segment, Delivery, illustrates how the attacker delivers the weapon, perhaps through a phishing email (depicted as an envelope with a warning sign). Exploitation represents the successful compromise of a system (shown as a cracked lock icon).

Installation, the next stage, shows the attacker establishing persistent access (a small green plant sprouting from the compromised system). Command and Control depicts the attacker’s communication with the compromised system (a satellite dish). Actions on Objectives illustrate the attacker’s goals, such as data exfiltration (data flowing out of the system). Finally, the last segment, Exfiltration, shows the attacker removing stolen data (a hard drive leaving the system).

Each segment should include annotations describing potential mitigation strategies, such as strong passwords, intrusion detection systems, and regular security audits.

So, I’m deep diving into cybersecurity research topics for my master’s, trying to find that sweet spot between practical application and theoretical depth.
