What is Traffic Light Protocol?
A simple label set (TLP:RED, AMBER, GREEN, CLEAR) that tells recipients how widely they may share a piece of information.
The Traffic Light Protocol is a set of labels that tell recipients how far they may share information. In version 2.0, maintained by FIRST: TLP:RED is for named recipients only, TLP:AMBER for their organisation and clients on a need-to-know basis (TLP:AMBER+STRICT for the organisation only), TLP:GREEN for the wider community, and TLP:CLEAR for anyone.
TLP covers sharing, not classification or encryption. It works because it is simple and widely understood across sharing groups, vendors and governments.
