Which of the following is NOT one of the criteria for information to be classified as SSI?

The classification of Sensitive Security Information (SSI) is based on specific criteria that help protect sensitive data related to transportation security. While options related to the nature of the information, such as being detrimental to transportation security or being related to it, are key characteristics that guide what qualifies as SSI, the idea that the information must fall under one of 20 categories is not a requirement for classification as SSI.

The classification process focuses on whether the information could harm transportation security if disclosed, rather than confining it to a strict categorization system. This understanding of SSI emphasizes its protective intent rather than strict categorization, making the assertion that it must fall under one of 20 categories inaccurate in the context of SSI classification.
