CERT Tonga uses TLP according to the FIRST Standard Definitions and Usage

TLP is a set of designations used to ensure that sensitive information is shared with the appropriate audience.

It employs four colors to indicate expected sharing boundaries to be applied by the recipients

RED:- Not for disclosure, restricted to participants only. Sources may use TLP:RED when information cannot be effectively acted upon by additional parties, and could lead to impacts on a party’s privacy, reputation, or operations if misused.

  • Who to share with: Recipients may not share TLP:RED information with any parties outside of the specific exchange, meeting, or conversation in which it was originally disclosed.

AMBER:- Limited disclosure, restricted to participants’ organizations. Sources may use TLP:AMBER when information requires support to be effectively acted upon, yet carries risks to privacy, reputation, or operations if shared outside of the organizations involved.

  • Who to share with: Recipients may only share TLP:AMBER information with members of their own organization, and with clients or customers who need to know the information to protect themselves or prevent further harm

GREEN:– Limited disclosure, restricted to the community. Sources may use TLP:GREEN when information is useful for the awareness of all participating organizations as well as with peers within the broader community or sector.

  • Who to share with: Recipients may share TLP:GREEN information with peers and partner organizations within their sector or community, but not via publicly accessible channels. Information in this category can be circulated widely within a particular community

WHITE:– Disclosure is not limited.
Sources may use TLP:WHITE when information carries minimal or no foreseeable risk of misuse, in accordance with applicable rules and procedures for public release

  • Who to share with: Subject to standard copyright rules, TLP:WHITE information may be distributed without restriction.
