About the Traffic Lights Protocol for labeling information
or: the FIRST TLP protocol
TLP provides a simple and intuitive schema for indicating when and how sensitive information can be shared, facilitating more frequent and effective collaboration. It employs four colors to indicate expected sharing boundaries to be applied by the recipient(s). (source)

Access Levels
ChatGPT, 14 februari 2025 Prompt: The FIRST.ORG TLP defines 4 levels of access to information. Describe each level in terms of individuals or groups to which access should be limited
Answer The Forum of Incident Response and Security Teams (FIRST) Traffic Light Protocol (TLP) defines four levels of access to information, each designed to facilitate secure and responsible sharing of sensitive information. Here's a description of each level:
-
TLP:RED - This level indicates that the information is highly sensitive and should be shared only with specific individuals who are directly involved in making decisions or taking actions in an incident response. The access is strictly limited to the people present at the meeting or explicitly named recipients. This level ensures that the information is not shared beyond this restricted group.
-
TLP:AMBER - Information classified under TLP:AMBER can be shared with individuals within a particular organization or group who need to know in order to mitigate risks. This level of access is typically restricted to a limited number of stakeholders within the organization and may include external parties if they are directly involved in the response or resolution.
-
TLP:GREEN - This level allows the information to be shared with peers and partner organizations within the broader community but not publicly. It is intended to encourage collaboration and information exchange while maintaining a level of confidentiality that prevents public distribution.
-
TLP:CLEAR (or formerly TLP:WHITE) - Information categorized under this level can be shared freely with the public. There are no restrictions on distribution, and the information can be shared with anyone, including the general public. This level is used for information that poses no direct security threat if widely disseminated.
These levels facilitate appropriate information sharing while protecting sensitive data and ensuring that it is accessed only by those who need it to effectively respond to security incidents.
