The Traffic Light Protocol
The EGI CSIRT employs a simple system known as the Traffic Light Protocol (TLP) to control sharing of potentially sensitive information.
The TLP is based on the concept of the originator labelling 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.
TLP colours
| 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. |
| 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. |
| 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 However, the information may not be published or posted on the Internet, nor released outside of the community. |
| WHITE | Unlimited | Subject to standard copyright rules, WHITE information may be distributed freely, without restriction. |
