The Federation of American Scientists put online a FOIA’d report from DHS that lists the titles of all DHS Sensitive Security Information (SSI) documents, as reported to Congress in January 2006.
There are a number of documents listed in this report that are rightfully shielded from public view, related to LNG facility and nuclear plant vulnerabilities, operational details about aviation screening, etc. But there are a number of documents that are inexplicably labelled as SSI.
For example, why is the World Customs Organization Framework of Standards to Secure and Facilitate Global Trade Implementation Plan considered as SSI? And why are the reports of results from Operation Safe Commerce classified at SSI? These are exactly the type of documents that need to be openly and publicly disseminated if they are going to have any security value, because the success of these initiatives depends upon unfettered public-private sector collaboration and open sharing of lessons-learned. By keeping documents like this as SSI, DHS is undermining the ability of private sector companies to be positive, proactive contributors on supply chain security.
