The Traffic Light Protocol (TLP) was created in order to encourage greater sharing of information. In order to encourage the sharing of sensitive information, however, the originator needs to signal how widely they want their information to be circulated beyond the immediate recipient, if at all. The TLP provides a simple method to achieve this. It is designed to improve the flow of information between individuals, organisations or communities in a controlled and trusted way. It is important that everyone understands and obeys the rules of the protocol. Only then can trust be established and the benefits of information sharing realised. The TLP is based on the concept of the originator labeling information with one of four colours to indicate what further dissemination, if any, can be undertaken by the recipient. The recipient must consult the originator if wider dissemination is required.
RED - personal for named recipients only
In the context of a meeting, for example, RED information is limited to those present at the meeting. In most circumstances, RED information will be passed verbally or in person. -- From Wikipedia, the free encyclopedia
AMBER - limited distribution
The recipient may share AMBER information with others within their organisation, but only on a need-to-know basis. The originator may be expected to specify the intended limits of that sharing. -- From Wikipedia, the free encyclopedia
GREEN - community wide
Information in this category can be circulated widely within a particular community. However, the information may not be published or posted on the Internet, nor released outside of the community. -- From Wikipedia, the free encyclopedia
WHITE - unlimited
Subject to standard copyright rules, WHITE information may be distributed freely, without restriction. -- From Wikipedia, the free encyclopedia
