What is MITRE?
MITRE is a US not-for-profit organisation that conducts research, development and consulting in the areas of national security, cybersecurity and technological innovation. Within the IT and OT world, MITRE is best known for its frameworks such as MITRE ATT&CK and MITRE D3FEND, which are used worldwide to provide a structured understanding of cyber threats and defence.
MITRE works with governments, defence, industry and critical infrastructures to improve the security of digital systems.
🧠 What does MITRE do?
MITRE maintains and develops several public knowledge bases and models, including:
- MITRE ATT&CK – Model that describes the tactics and techniques of cyber attackers
- MITRE ATT&CK for ICS – Specific variant aimed at OT environments and industrial networks
- MITRE D3FEND – Counterpart to ATT&CK, with defensive measures and security controls
- CVEs (Common Vulnerabilities and Exposures) – MITRE manages the central database of vulnerabilities
- Engagements with NIST, DHS and DoD – Support for standards and critical infrastructures
MITRE provides open and structured models that organisations can use to improve their cybersecurity.
🏭 Relevance of MITRE in industrial networks
- ATT&CK for ICS helps to understand cyber incidents involving PLCs, HMIs, SCADA and field devices
- D3FEND supports the selection of effective defensive measures within Defense in Depth architectures
- MITRE CVEs are used in Vulnerability Management and patch management
- Security teams use MITRE frameworks to design SIEM rules, Threat Hunting, SOC processes and Incident Response
MITRE knowledge is widely applied in IEC 62443, NIS2 and at national cybersecurity centres (such as the NCSC).
🔍 Comparison of MITRE models
| Model | Purpose | Application in OT |
|---|---|---|
| MITRE ATT&CK | Attack techniques and tactics | Threat simulation, detection strategies |
| MITRE ATT&CK for ICS | Attacks on industrial networks | Securing physical processes |
| MITRE D3FEND | Defensive measures | Linking controls to attacks |
| MITRE CVE | Central database of vulnerabilities | Input for risk and patch management in OT/IT |
🔐 Security considerations
- MITRE frameworks help organisations to secure themselves in a structured, risk-based manner
- Foster collaboration between Blue Team, Red Team and Purple Team
- Support threat modelling, Security Monitoring and Zero Trust principles
- Many tools (such as SIEM, SOAR, EDR) use MITRE as a reference for detection and response
MITRE provides a uniform language and methodology, essential for multidisciplinary security.
📌 In summary
MITRE is a global authority on cyber threats and defence, with powerful models such as ATT&CK, D3FEND and CVE. In an OT context, MITRE provides insight into attacks, vulnerabilities and the appropriate defensive measures.
