Securely deleting sensitive files

Keeping your Workstations Safe File “Shredding”: Did you know that deleting a file in Win/Mac/Linux leaves traces of it behind on your hard-drive? The "delete" operation in Windows and other operating systems only removes bits of information from files so they just appear deleted in OS. They are actually till there, on your hard-drive, but they have just been dis-associated from the file table. It is easy to retrieve those files using widely available specialized file recovery software. You do not want to leave traces of sensitive identifiable patient information lying around on your network workstation hard drives! The one and only place where patient files should permanently reside is on your secure and fully backed up OSCAR EMR server. In order to remove, or “shred” files permanently from all your office workstation computers you have to use a program that is capable of rewriting the files with random series of binary data multiple times. This process is often called shredding. That way, the actual content of the file has been overwritten and the possibilities to recover such a shredded file are mostly theoretical.

Keeping your Workstations Safe File “Shredding”: For Windows and Ubuntu a good Open Source file shredding program is: BleachBit http://bleachbit.sourceforge.net/

Keeping your Workstations Safe With a few simple steps you can protect your patients' privacy in the medical office. It is also important to rotate passwords regularly. Use strong passwords: ie 6 to 8 characters, mix of cases, mix of alpha, numbers and special characters, eg: @bcD!234 Be sure to maintain good security habits in the office. Never leave an unattended workstation unprotected.
