Explanation/Notes: While shredding hard-copy documents is commonplace these days, company workers may overlook the threat of discarding electronic media that contained Sensitive data at any time. Computer attackers attempt to recover any data stored on discarded electronic media. Workers may presume that by just deleting files, they ensure that those files cannot be recovered. This presumption is absolutely incorrect and can cause confidential business information to fall into the wrong hands. Accordingly, all electronic media that contains or previously contained information not designated as Public must be wiped clean or destroyed using the procedures approved by the responsible group.
