I have just heard that the Ministry of Justice has lost some highly sensitive information on discs being sent in the post.

This, after the totally embarrassing loss of millions of items of personal details by HMRC a few years ago on discs being transported by courier.

Will they ever learn?

We have no choice but to provide details to the police and government agencies when instructed to do so.  But at least we can be better than them.  If it is sensitive, deliver it in person, or use a really trustworthy courier.  Also why not encrypt the data so if it gets lost it is no use to anyone else.  Of course, you need to take a back-up copy so you are able to function normally even if you lose it.

It is no use worrying about cyber security if you do not pay attention to low-tech security too.
