What is SSI?
Sensitive Security Information is information that, if publicly released, would be detrimental to transportation security, as defined by Federal Regulation 49 C.F.R. Part 1520.
As persons receiving SSI in order to carry out responsibilities related to transportation security, TSA stakeholders and non-DHS government employees and contractors, are considered “covered persons” under the SSI regulation and have special obligations to protect this information from unauthorized disclosure.
