CHAPTER 1: CARELESSNESS
āHuman error is overwhelmingly stated as the greatest {security} weakness this year (86%), followed by technology (a distant 63%) ... Unless robots replace the human workforce (unlikely in the lifetime of anyone reading this report), human error is an issue that companies will continue to deal with.ā
Deloitte, 20092
Letās look at some of the ways that human nature can contribute to security breaches, beginning with carelessness.
Barely a week goes by without a report of a laptop, or a USB stick containing sensitive information, being left on a train, or being stolen when left in plain view on the back seat of a car. Modern electronic equipment is highly portable, and can hold staggering amounts of data. Employees are actively encouraged to take advantage of this portability, to work on the move, and at home, so they can hardly be criticised when they do. Weāre not just talking about laptops either. Itās easy to underestimate the volume and value of information stored on smart phones, and the other devices that are used in both our business and our personal lives.
In times gone by, people going to meetings would just pack their briefcase with the papers they needed on the day. Everything else got left behind. Now, we can take everything but the proverbial kitchen sink with us ā all our correspondence on every topic, every report thatās crossed our desk, and far more besides.
In some ways, itās an advantage. Thereās no chance of getting to a meeting only to discover you left the most critical document behind. But in other ways, itās a big problem. By taking so much with you, youāre putting so much more at risk.
In January 2008, for example, a laptop was stolen from a Royal Navy recruiting officerās car. It contained personal information about 600,000 people who had joined Britainās armed forces, or expressed an interest in doing so3. The problems this could have caused are clear. As the Secretary of State for Defence at the time said, not only were details of bank accounts revealed, but the home addresses (and thus lives) of soldiers, sailors and airmen.
Such incidents are commonplace. Also in 2008, a consultant working for the Home Office copied the details of thousands of criminals onto a memory stick ā then lost it. Data about 84,000 criminals was put at risk4. In 2009, a council worker lost a memory stick containing the names and bank details of more than 1,000 housing-benefit recipients5. And in 2010, the American healthcare provider, Kaiser Permanente, reported that a device stolen from an employeeās car had contained records relating to 15,000 patients6.
The cost of responding to such incidents is huge ā the Ponemon Institute says American companies spend an average of US$204 for every customer record lost7.
So what can we do to reduce the likelihood and consequences of an incident?
The most obvious answer is to take only what you need with you. Itās tempting to carry extra information on a ājust in caseā basis, or because itās easier to download complete databases than extract specific details. Taking a back-up copy on a USB stick may seem like a sensible precaution, but that also doubles your chances that the data will go missing. This goes for paper copies too, and while a paper document carries less information than a PC, the information is exposed for all to see.
Remote access facilities are so much better than they were, and are so much easier to use. Furthermore, public hotspots are spreading, and Wi-Fi is even available on some trains. (Note, however, that āfree public Wi-Fiā is not always what it seems.)
This removes the need for people to carry so much data around with them. The principle is a simple one: data is far safer when itās kept on central servers that are properly secured and managed. So, the best option is for people to leave it there and access it remotely, as and when required.
But what about the data people really do have to carry around? For that, full-disk encryption of built-in hard disk drives, and the automatically-enforced encryption of USB drives, is highly recommended. It may sound complicated, but it isnāt difficult ā or expensive ā to do. Hardware-based solutions that can secure entire disks to standards that far exceed most organisationsā needs, are available for as little as Ā£200. Software-based solutions that protect data, file by file, are cheaper still, at Ā£50 or less a machine. This may sound a lot, when compared to the falling prices of computer hardware. You can get a powerful laptop PC for a few hundred pounds, for example. But remember, the data on a device can be worth far more than the device itself. In that context, encryption is a bargain.
Remember also that the data is valuable to you, as well as to any thief. If your only copy of the 300-page report youāve been writing is on the laptop that has just gone missing, it could really spoil your day! So, back-up your important work, ideally every day, and keep the copy safe and well away from the original.
Finally, it pays to be vigilant. Do not leave valuable equipment and documents unattended, and in plain view. If youāre travelling by car, lock your laptop in the boot, rather than leaving it in the seat where it can be seen. Remember, that in some foreign countries, industrial espionage is rife ā and even state-sponsored ā so locked hotel rooms cannot be considered secure. Also, be aware of who is around you while you are working. Can the sensitive information on your screen be seen by the man or woman in the seat behind? And be careful what you say on the phone in public places. Think of what the consequences would be if someone working for one of your fiercest competitors was sitting at the next table.
