The unencrypted hard drive - missing from a prison…



The Information Commissioner’s Office really had no choice but to come down hard on the National Offender Management Service recently, after a portable hard drive used to back up the prisoner intelligence database went missing from a prison security department.

Although nobody knew when it had actually gone missing, it could have been gone for almost a week since it had last been used on 18 May 2013 for the weekly back up - but was missing when staff went to back up six days later. It had not been locked in the fireproof safe afterwards, contrary to policy.  Not only was it missing, it was also unencrypted and had not been password protected. It contained sensitive information about almost 3000 prisoners, including names and dates of birth, length of sentence, offence(s), physical descriptions and distinguishing marks, plus intelligence information about drug use and links to other prisoners or organised crime - certainly not the sort of details you’d want to lose.

Although only nine staff members had access to the area where the hard drive was used and the area was controlled by a keypad system, the door to the Security Department could be opened by anyone on the prison staff.

To make matters worse, this wasn’t the first time something like this had happened. Back in October 2011, an almost identical breach involving 16,000 prisoners in another establishment had taken place, and the ICO had been told that because of this, encrypted hard drives had been supplied to 75 prisons that had been using unencrypted portable hard drives to back up prisoner intelligence information. Unfortunately, nobody realised that the encryption software required manual activation and the IT provider was never asked to check that the encryption software was working, so all the 75 prisons carried on using insecure portable hard drives for at least a year afterwards.

The software has now been activated and automatic upgrades enabled. The hard drive was never recovered although it doesn’t appear to have been accessed and there was no evidence that it fell into the wrong hands.

Because there had already been a virtually identical serious breach, the Commissioner considered that this was a very serious contravention of the seventh data protection principle;
Appropriate technical and organisational measures shall be taken against unauthorised or unlawful processing of personal data and against accidental loss or destruction of, or damage to, personal data”

The National Offender Management Service was fined £180,000. It just underlines the fact that even though you think you’re doing everything you can to comply with the rules, sometimes it can be the simplest thing you overlook that can lead to a damaging security breach. 

Do you know where your backup drives are kept, and have official policies in place to ensure that they don’t go missing? Are the drives encrypted? Can you imagine what would happen if the personal information you keep backed up were to be lost, either for your business or your clients?
