Traffic Light Protocol

Like other cyber security teams, GAZ-SYSTEM CERT uses the Traffic Light Protocol (TLP). The protocol is designed to control and encourage the sharing of information.

What is TLP?

Traffic Light Protocol is a set of rules, grouped into four categories, used to better define the audience of sensitive information. For ease of reference, the categories are marked with four colours (red, amber, green and white). It is up to the organisation from which the information originates to determine which category is appropriate. If the recipient wishes to share the information with a broader audience, he or she must obtain appropriate approval from the author of the message.

Meaning of the TLP colours for message recipients


Recipients may not share transmitted information with anyone except other recipients of these messages


Recipients may only share information within their organization (and its customers) with those who need to know the messages and only to the extent necessary to take appropriate action


Recipients may share information with their colleagues, within their own and partner organizations, and in their community. However, this information cannot be shared through public information channels


Distribution of the information is not subject to any restrictions (except copyright)


Information about the TLP used should be included in the header or footer of a transmitted message, using a notation in the format: "TLP: [Colour]". Traffic Light Protocol does not apply to government secret or confidential information. When contacting GAZ-SYSTEM CERT, please mark the information according to the TLP rules. TLP-marked correspondence should indicate the colour in the subject line and in the body of the email, immediately before the specific information itself.

TLP colour should be indicated in capital letters: TLP: RED, TLP: AMBER, TLP: GREEN or TLP: WHITE
