CISA TLP definition updates #583

Open chadillac opened 10 months ago

chadillac commented 10 months ago

CISA has new guidance on TLP markings and modifications... the stix2(.1) common.py configs do not reflect this more recent guidance...

https://www.cisa.gov/news-events/news/traffic-light-protocol-tlp-definitions-and-usage

TLP: WHITE --> TLP: CLEAR +TLP: AMBER+STRICT

These markings should be included in common config as they're officially part of the guidance now and already in use and will be in use going forward.

@chadillac,

An extension has been implemented to support TLP2 - see:

https://github.com/oasis-open/cti-stix-common-objects/tree/main/extension-definition-specifications/tlp-2.0

If this is satisfactory for you needs, please close this issue.

What's the decision making process around adding a dependency to that repo rather than simply adding it to the already-embedded list of acceptable TLPs here?
