Traffic Light Protocol (TLP)
Just like other cyber emergency teams, the CERT. uses the “Traffic Light Protocol”, or TLP for short. This has been developed to facilitate and encourage the exchange of information in a safe manner.
What is it?
The protocol requires that the person sending information assigns it a colour using a colour code. This colour indicates if and in what ways this information may be further disseminated. Someone who receives info, and believes that certain info can be disseminated on a greater scale, must first ask for permission from the sender.
Why use TLP?
The CERT works in close collaboration with various international organisations to identify cyber incidents and to coordinate responses to those incidents.
The TLP provides a simple and intuitive scheme to indicate when and how sensitive information can be disseminated within the worldwide cyber security community. The sharing of this information ensures more frequent and effective collaboration between the CERT and its partners.
Who uses TLP?
Besides the CERT, numerous public services and private businesses across the world use TLP.
