MITRE ATT&CK Framework for Regulated Industry Threat Modeling

MITRE ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge) is a globally accessible knowledge base of adversary behavior based on real-world observations, maintained by MITRE and updated quarterly. The Enterprise matrix (current version: v15, released October 2024) covers 14 tactics, over 200 techniques, and 400+ sub-techniques across Windows, macOS, Linux, cloud (AWS/Azure/GCP/Office 365), network, and containers. Separate matrices exist for ICS (Industrial Control Systems) and Mobile environments. Each technique entry includes a description, procedure examples (real APT group usage), detection recommendations, and mitigation mappings. ATT&CK is referenced by CISA advisories, FBI Flash reports, DORA threat-led penetration testing (TLPT) under TIBER-EU, and FFIEC cybersecurity guidance as a standard vocabulary for describing adversary behavior.

In regulated industries, ATT&CK serves three primary engineering functions. First, threat modeling: mapping an organization's crown-jewel systems (customer PII, payment card data, ePHI, trading systems) against ATT&CK techniques most relevant to threat actors targeting the sector — identified from CISA KEV, sector ISACs (FS-ISAC, H-ISAC), and ATT&CK Groups database. Second, detection coverage analysis: using ATT&CK Navigator to visualize SIEM detection rule coverage against the technique matrix, identifying blind spots where no detection exists. This is directly relevant to DORA Article 25 (advanced testing) and TIBER-EU requirements. Third, purple teaming: structuring adversary simulation exercises where red team actions are mapped to specific ATT&CK technique IDs, enabling precise measurement of detection and response capability.

A nuanced application of ATT&CK in financial services is mapping the ICS matrix against operational technology (OT) environments in clearing houses, exchanges, and energy trading platforms. ATT&CK for ICS v3 covers techniques specific to manipulation of control systems, inhibit response to function, and impair process control — which are distinct from enterprise IT attacks. For healthcare, ATT&CK technique T1486 (Data Encrypted for Impact — ransomware) and T1190 (Exploit Public-Facing Application) are the highest-frequency techniques in HHS OCR breach notifications, making them priority detection targets. Regulated firms using ATT&CK for TLPT under TIBER-EU must have their threat intelligence providers produce Targeted Threat Intelligence (TTI) reports that explicitly map adversary profiles to ATT&CK techniques relevant to the firm's business model and geographic footprint.

We conduct ATT&CK-based threat modeling engagements that identify sector-relevant adversary groups, map attack paths against the client's environment, perform ATT&CK Navigator-based detection coverage analysis, and produce prioritized control improvement roadmaps. Our output supports TIBER-EU TTI requirements, DORA advanced testing obligations, and SIEM detection rule development.
