Universal, Non‑overlapping Cyber Threat Language

The Universal Cyber Threat Framework Bridging Strategy, Operations & Development

TLCTC is the Rosetta Stone for Cyber Risk.

10 logically‑derived, non‑overlapping cyber threat clusters that connect strategic cyber risk & -security management, operational security, and secure development into one common language.

The Bow-Tie Model

Cause → Incident → Consequence

The Power of Causality
A risk event is a deviation from a strategic goal. IT Goal: "Operate securely" • Risk Event: "Compromise of System" GOVERN — Risk Appetite, Responsibilities, Metrics (Cross-cutting) CAUSE SIDE Threat Clusters RISK EVENT / INCIDENT Asset Compromise CONSEQUENCES CONTROL PROTECT IDENTIFY (indirectly) CONTROL DETECT CONTROL RESPOND CONTROL RECOVER Preventive controls affect the likelihood of an event occurring Detective and reactive controls influence the consequences "A control failure is a control risk — it is a deviation from the control objective"

Control Matrix — 60 Control Objectives

10 Threat Clusters × 6 NIST CSF Functions · each cell holds Local + Umbrella controls (Whitepaper §8.1, §9)

All other Local & Umbrella controls remain cluster-specific (Whitepaper §8.1.3, §9).

Attack Paths — Three-Layer Model

Horizontal cause-side TLCTC sequence (SRE) · vertical escalation to DRE · further escalation to BRE

Open Architect
BRE Business Risk Event organizational consequence DRE Data Risk Event C / I / A on data assets SRE System Risk Event cause-side TLCTC sequence BRE Fraudulent transfer financial loss no BRE DRE present, but no organizational consequence no BRE no DRE means no escalation path DRE: C Credentials exposed phished by user no DRE credential USE only (R-CRED rule) DRE: I Wire transfer altered payment integrity Δt: 5m Δt: 2h #9 SOCIAL ENGINEERING BRIDGE #4 IDENTITY THEFT INTERNAL #1 ABUSE OF FUNCTIONS INTERNAL phishing email delivers credential form attacker logs in as the user approves wire transfer via legitimate function ||boundary|| eBanking example: phishing → identity theft → function abuse. Each step escalates only as far as it can — no DRE means no BRE.
