Glossary

Acronyms and frameworks used across the cs-graph, with cross-links.

A

AI Act

Regulation (EU) 2024/1689 — the EU's horizontal AI regulation. Art. 15 codifies the cybersecurity-of-high-risk-AI obligation. cs-graph maps every ATLAS technique to the relevant AI Act article.

AI Act Art. 15

ATLAS

MITRE Adversarial Threat Landscape for AI Systems. The ATT&CK-style knowledge base for adversarial-ML techniques — 170 techniques across 16 tactics covering prompt injection, model poisoning, model evasion, model theft, and supply-chain compromise.

ATT&CK

MITRE Adversarial Tactics, Techniques, and Common Knowledge. The canonical catalogue of adversary behaviour — 14 tactics, ~200 techniques and ~400 sub-techniques in the Enterprise matrix. cs-graph mirrors the v14.1 STIX bundle.

C

Corroborator

The ODKE+ pipeline stage that converts evidence count into a confidence score. Deterministic curve: 1 → 0.65 · 2 → 0.80 · 3 → 0.95 · 4+ → 1.0. Primary catalogues bypass the curve at 1.0.

ODKE+ methodology

CRA

CVE

Common Vulnerabilities and Exposures. The canonical ID format for publicly known vulnerabilities. cs-graph ingests CVE entries from the NVD year feeds filtered to CVSS ≥ 8 or KEV-listed.

Vulnerability index

CVSS

Common Vulnerability Scoring System. The 0–10 severity score attached to CVEs. cs-graph uses CVSS v3.x baseScore + vector + exploitability/impact components.

CWE

MITRE Common Weakness Enumeration. The canonical catalogue of software weakness classes — 969 entries in CWE 4.20. cs-graph mirrors the full catalogue and maps each weakness to the techniques that exploit it.

Weakness index

D

D3FEND

MITRE Defensive ontology. The defensive counterpart to ATT&CK — 271 defensive techniques across 6 tactics (Model, Harden, Detect, Isolate, Deceive, Evict, Restore) with cross-walks to the techniques they counter.

Defense index

DORA

EU Digital Operational Resilience Act — Regulation (EU) 2022/2554, in force 2025-01-17. Mandates ICT risk management, incident reporting, and annual penetration testing (Art. 24) plus threat-led pen testing (Art. 25) for EU financial entities.

DORA Art. 24

E

EPSS

Exploit Prediction Scoring System. A daily-updated probability (0.00–1.00) that a CVE will be exploited in the wild within the next 30 days. Published by FIRST.org. cs-graph enriches every Vulnerability node with the current score and percentile.

F

FIRST

GDPR Art. 32

Grounder

The ODKE+ pipeline stage that validates every edge's `from` and `to` slug resolve in the canonical node collection before promotion. Catches LLM hallucinated IDs at the schema boundary.

GTFOBins

Curated catalogue of Unix binaries that can be abused to bypass local security restrictions — sudo, suid, file-read/write, shell escape, privilege escalation. 478 entries in the cs-graph mirror.

LOLbins index

H

HIBP

Have I Been Pwned. Troy Hunt's catalogue of disclosed data breaches. cs-graph mirrors 978 entries (filtered to exclude fabricated and spam-list) with pwn_count, data_classes, and breach metadata. No PII surfaced.

Breach index

I

IAP

Google Cloud Identity-Aware Proxy. The auth gate in front of kb.squr.ai — only `jorian@squr.ai` and `adam@squr.ai` reach the IAP-gated Cloud Run preview. The public kb.squr.ai launches once content review completes.

ISO 27001

ISO/IEC 27001:2022 — Information Security Management Systems. Annex A controls A.5.7, A.5.23 and the A.8 (Technological) subset are mega-mapped in cs-graph.

ISO 27701

ISO/IEC 27701:2019 — Privacy Information Management extensions to ISO 27001. cs-graph maps the controller-side controls (A.7.x) and processor-side controls (A.8.x).

J

Jaccard

Jaccard similarity. Set-overlap metric used on the framework crosswalk page (`/explore/crosswalk`): `|A ∩ B| / |A ∪ B|` over the ATT&CK technique sets each framework tests.

Crosswalk

K

KEV

CISA Known Exploited Vulnerabilities catalogue. The federally-maintained list of CVEs that have been actively exploited in the wild — 1,606 entries in the cs-graph mirror, refreshed weekly.

KEV explorer

L

LOLBAS

Predicate

The verb of a graph edge — `uses`, `mitigates`, `defends_against`, `exploits`, `compliance_tests_technique`, etc. cs-graph enforces a from-type → predicate → to-type invariant at the schema layer to catch mis-typed edges before they enter the graph.
