Top Level Cyber Threat Clusters

The Universal Framework Bridging Strategy, Operations & Development

White Paper V1.7

The Top Level Cyber Threat Clusters (TLCTC) framework serves as a "Rosetta Stone" connecting strategic planning to operational security through logically-derived, non-overlapping threat categories. This fills a critical gap in current standards while complementing existing cyber risk management approaches.

The Missing Link in Cybersecurity

Today's cybersecurity landscape is fragmented across three critical levels, each speaking a different language. TLCTC provides the universal framework that connects them all.

STRATEGIC Risk Management ISO 27005 • NIST CSF FAIR • Enterprise Risk OPERATIONAL Security Operations MITRE ATT&CK STIX/TAXII • CVE DEVELOPMENT Secure SDLC SSDLC CWE • CVE TLCTC Universal Framework Communication Gap Language Barrier Integration Gap

The Problem

  • • No common threat taxonomy
  • • Disconnected frameworks
  • • Communication barriers
  • • Siloed operations

The Solution

  • • 10 universal threat clusters
  • • Standardized attack notation
  • • Common vocabulary
  • • Framework integration

The Result

  • • Unified risk management
  • • Clear threat communication
  • • Integrated security
  • • Strategic alignment

Value for All Stakeholders

TLCTC delivers clear benefits across strategic leadership, technical teams, and regulatory bodies.

Strategic Leadership

  • Enhanced Strategic Decision-Making
  • Quantifiable Risk Management
  • Improved Board-Level Communication
  • Stronger Cybersecurity Governance

Security Operations & Technical Teams

  • Consistent Incident Classification (CSIRTs/CERTs)
  • Enhanced MITRE Integration (ATT&CK, CAPEC, CWE)
  • Streamlined Threat Intelligence Sharing (STIX)
  • Precise Attack Path Analysis for SOCs
  • Standardized Threat Intel Framework
  • Improved Vulnerability Prioritization (CVEs)

Standards Bodies & Regulatory Agencies

  • Developing Clearer Threat Standards (NIST/ISO/CIS)
  • Framework Harmonization (CISA/ENISA)
  • Global Consistency for EU Agencies
  • Enhanced National & International Coordination (NCSCs)
