Unfortunately, nothing new! ‘Just’ another USB stolen in a school in Woodbridge, Virginia, USA. The content: personal information about students. What I couldn’t understand was this phrase in a letter to parents from the Principal of Lake Ridge Middle School: “Unfortunately, it is difficult to prevent the loss of confidential data resulting from unanticipated criminal activity.” Well, fortunately, it is simpler than he thinks to protect confidential data: encryption! There are some free tools out there that every school principal, teacher and even student should know about, such as, TrueCrypt.
