The list provides a good overview of classification markings, also called security markings. For all these the ClassifyIt tool provides a sound basis to implement and support your users on the best protection of your information and documents.
Traffic Light Protocol (TLP)
A very easy and intuitive classification marking policy for your sensitive and un-sensitive data. The Traffic Light Protocol (TLP) is used by Computer Emergency Response Teams (CERTs) to provide classification markings to their documents when exchanging with other CERTs. TLP is a real standard which could be used by any entity (company or agency) to apply classification marking, and therefore data protection rules and regulations, to their documents.
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 organization, 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 However, the information may not be published or posted publicly on the Internet, nor released outside of the community.
WHITE - unlimited
Subject to standard copyright rules, WHITE information may be distributed freely, without restriction.
