Cyber Soldier project - A threat-led methodology for assessing the Digital Resilience of cybersecurity systems

We present Cyber Soldier Methodology and tool set that introduces a threat-led methodology for assessing the digital resilience of cybersecurity systems within organizations required to comply with European regulatory frameworks such as the Digital Operational Resilience Act (DORA). Unlike traditional vulnerability assessments or penetration testing, this methodology focuses on reproducing the tactics, techniques, and procedures (TTPs) of real adversaries to evaluate the effectiveness of cybersecurity controls and operational resilience mechanisms in production environments. The proposed methodology integrates threat intelligence, red team scenario design, and detection performance analysis into a unified process aimed at measuring the organization’s preparedness for sophisticated cyber threats. We demonstrate how the presented framework bridges the gap between strategic compliance requirements under DORA and the operational practice of resilience testing. We also provide some initial data the application of Cyber Soldier toolset in real-world environments.
