What is a "classification guide"?

A "classification guide" is a vital document that provides comprehensive guidance on how to classify specific types of information appropriately. It serves as a reference for individuals who handle classified data, outlining the criteria and considerations that must be taken into account when determining the classification level of various information. This ensures consistent application and understanding of classification standards across different users and situations.

The purpose of the classification guide is to ensure that classified information is protected appropriately, minimizing the risk of unauthorized disclosure while maintaining operational effectiveness. By following a classification guide, personnel can make informed decisions that align with established security policies and requirements.

The incorrect options do not accurately describe what a classification guide is. While an overview of classification levels offers a general understanding, it lacks the specificity and guidance concerning individual pieces of information that a classification guide provides. Resources for unclassified information are distinct from classification guides, as unclassified materials do not require such classification efforts. Lastly, although training manuals may include sections about classification authorities, they do not fulfill the specific purpose of providing guidance on classifying particular types of information, which is the primary function of a classification guide.
