MITRE ATT&CK
Public knowledge base of documented adversary tactics and techniques.
Broninformatie
- Gecontroleerde gegevens of maatstaf
- ATT&CK is a knowledge base grounded in observations. Its domains include Enterprise, Mobile and ICS.
- Praktisch gebruik
- Connect a technique with a trace and detection hypothesis. Distinguish having a log source from actually testing detection.
- Te behouden beperking
- A shared technique cannot establish actor attribution. Technique coverage counts do not fully measure security.

FIRST · EPSS
Vulnerability exploitation probability model. Compare with technical severity, local exposure and business impact.
Broninformatie
- Gecontroleerde gegevens of maatstaf
- The model looks ahead 30 days. Its score is a probability; its percentile ranks that score relative to other CVEs.
- Praktisch gebruik
- Record the data date and distinguish probability from percentile. Add asset exposure and confirmed exploitation evidence.
- Te behouden beperking
- The model does not predict harm to your organisation. Low probability does not cancel a critical exposure.

CVSS, EPSS, KEV en VEX
What is the estimated probability of observing exploitation of this CVE in the next thirty days?
It does not describe compromise of your instance, its controls or business loss.

FIRST · Traffic Light Protocol
Security information-sharing designations set by the source. Check their meaning before redistribution.
Broninformatie
- Gecontroleerde gegevens of maatstaf
- TLP 2.0 uses RED, AMBER, GREEN and CLEAR; AMBER+STRICT restricts sharing to the recipient organisation. Labels must not be translated.
- Praktisch gebruik
- Keep the marking with the information and check recipients before forwarding. Ask the source to clarify any ambiguity.
- Te behouden beperking
- TLP is neither a formal classification nor a reuse licence. It does not guarantee content accuracy.
Documentatie geraadpleegd op
STIX-indicatoren en TLP-deling
A traceable note does not by itself grant permission to redistribute it. TLP markings, additional restrictions and intended recipients must accompany a redaction or publication decision.
TLP describes a sharing scope; it certifies neither accuracy, official classification nor a usage licence. Encryption and retention rules need separate definition. Obtain explicit source permission before widening the received scope.

ICANN · Registration Data Lookup
Domain registration data lookup. Redacted data or a technical provider alone cannot establish control by an entity.
Broninformatie
- Gecontroleerde gegevens of maatstaf
- RDAP is the registration data access protocol. ICANN Lookup provides access to available public registration data.
- Praktisch gebruik
- Keep the exact domain, consultation date and result. Distinguish registrar, technical service and the entity operating a website.
- Te behouden beperking
- Data may be redacted or limited. Domain information alone cannot attribute content or an operation to a person.

OASIS · STIX 2.1
Describe threat intelligence through structured objects and relationships.
Broninformatie
- Gecontroleerde gegevens of maatstaf
- STIX 2.1 is an OASIS Standard dated 10 June 2021. It defines objects, properties and JSON serialisation.
- Praktisch gebruik
- Keep identifiers, dates, provenance and relationships. Check that the recipient interprets the same object type and validity period.
- Te behouden beperking
- A syntactically valid object can still be stale, misattributed or weakly supported.
Documentatie geraadpleegd op
STIX-indicatoren en TLP-deling
Structured intelligence retains provenance and a version history. For an actionable OSINT note, separate collected facts, the producer’s assertion and the local conclusion, then state what still needs confirmation.
Version note: at review time the OASIS latest-stage URL points to a document dated 2 April 2025 titled STIX 2.1 Errata 01, incorporating Draft 01. Its draft errata status is retained in the citation; it is not presented as a newly approved final version. Agree marking encodings with the recipient and check the edition actually used.

Exchange threat intelligence through an application protocol.
Broninformatie
- Gecontroleerde gegevens of maatstaf
- TAXII 2.1 is an OASIS Standard dated 10 June 2021. It includes service discovery and access to collections.
- Praktisch gebruik
- Test authentication, collection permissions, pagination and recovery after interruption. Record which objects were actually received and processed.
- Te behouden beperking
- TAXII transports data; it replaces neither the content model nor assessment of reliability.

C2PA · Content Credentials
Describe and verify certain content provenance information.
Broninformatie
- Gecontroleerde gegevens of maatstaf
- C2PA specification 2.4 defines manifests, assertions and cryptographic binding mechanisms associated with media.
- Praktisch gebruik
- Examine what the manifest asserts, who signed it and whether validation succeeds. Test preservation after transformations and distribution.
- Te behouden beperking
- Validated provenance does not establish the truth of a scene. Absence of a manifest does not demonstrate a fake.

Mediaherkomst en C2PA-validatie
A provenance report combines findings with different scopes. Signature, credential trust, content binding and scene context are separate assurances. Retain the exact asset and full report before summarising a result.
This JSON-LD representation is a derived view of C2PA data for reporting and interoperability. It is not independently verifiable or a validation input format.
