The Social Security Administration has asked the Office of Management and Budget (OMB) to approve the publication of new regulations:
... to create a Security and Suitability Files system to cover any additional security and suitability related information generated by SSA that is not sent to the Office of Personnel Management. We will use the information we collect to conduct background investigations and establish that applicants or incumbents, either employed by SSA or working for SSA under contract, are suitable for employment with us. ...
This is just a proposal. The public can comment on it once it is published in the Federal Register. To me, it sounds a bit sinister but it's probably benign.
