The Sf-86 is a questionnaire you will need to fill out if you are applying for security clearance. You must fill this out correctly or risk rejection of your application altogether. Even a small mistake on this form could hurt your chances of getting the clearance you need.  Sf-86 illegal downloading One part of the Sf-86 that often causes people problems has to do with downloading. The application lists illegal downloading in section 27, Use of Information Technology Systems. It asks if you have “introduced, removed, or used hardware, software, or media in connection with any information technology system without authorization, when specifically prohibited by rules, procedures, guidelines, or regulations.”  Lots of people have different interpretations of this section. In general, downloading music, even if you didn’t pay for it, is not always illegal. If you file share within a commercial relationship, this is usually illegal. It is always better to be safe and speak to an attorney experienced with security clearance. Contact Aiden Wilkie if you are unsure if your past use of the internet might have been illegal.
