Signs that the Media Understands Encryption

September 10th, 2009

I was amazed when I read about one of the latest data breaches in the Birmingham News.  I was not amazed that there was another data breach at a hospital – in a recent post Data Loss is the Other Guy’s Problem we talked about how hospitals are one of the places most prone to data breaches.  I was not amazed that this event took place in the United Kingdom because we have given Kudos to the United Kingdom and their Financial Services Authority (FSA) in prior posts.

What did amaze me was that the media got it right!  The Birmingham News clearly identified the real issue not once but twice in this article:

1 – “None of the information on the missing laptops had been encrypted.”
2 – “A Trulife spokeswoman said although the laptops were password protected they had not been encrypted, and only contained “basic information” of name, address, date of birth, hospital number and orthotics appliance prescription.”

Let’s backtrack a bit on the details.  Laptops containing the private and medical details of more than 7,000 Birmingham NHS patients, including sick children, have been stolen prompting a massive security alert.  The first laptop went missing at the premises of a Birmingham hospital in March 2006, a second was stolen in a mugging in March 2007 and the third was stolen after being left in a Trulife employee’s car in February last year.

My guess is that you, like patient Yvonne Dass, are wondering why the reporting is taking place in 2009 for data stolen over the last three years.

“The letter says Trulife is truly sorry but that does not explain why it has taken so long to let people know that such personal information is in the hands of a stranger, who could use it for the wrong reasons,” said Yvonne.

Well the answer, albeit not a convincing one,  is that is was only recently that Trulife discovered that the laptop held data about Sandwell and West Birmingham Hospitals NHS Trust patients.  Alan Taman, of Birmingham Children’s Hospital, said: “Trulife informed us at the end of May about the potential loss of data related to our patients and we immediately instigated an internal investigation to ascertain the nature of the data loss and the risks that our patients were exposed to.”

So once again we mourn that innocent bystanders, these hospital patients, are having to deal with the hassles of potential identity theft.  However, the fact that the mainstream media is starting to understand and report on the benefits of encryption bodes well for the future of both individuals and companies doing more to protect their computers.

Universities Need to Learn About Encryption

September 5th, 2009

Universities have unique challenges when it comes to security – both physical and digital security.  A university (or college, or community college, secondary school etc.) has almost every disadvantage when it comes to security.  As we’ve discussed, while you might think that Data Loss is the Other guy’s problem – that is not the case if you are at a University.

In the physical world transient populations make crime easy because a criminal won’t stand out in the crowd.   Universities are nothing if not transient in nature.  Likewise, facilities open at all hours make crime easy.  From dorms, to study halls to libraries – student life is a 24 by 7 event making it hard to control access.

In the digital world universities fare no better.  Standard devices make security easier – not possible in a world with thousands of instructors and students.  Likewise, the very nature of education requires that information be made available as often and as easily as possible.

So it comes as no surprise that today we’ll look at the California State University in Los Angeles, California in the United States which is our latest victim to computer theft.  A total of 14 computers were stolen, including two desktops.   If disk drive encryption had been in use, than the University would not have been required to report the theft.

The theft itself was pretty easy to perpetrate.  The door to the room containing the computers had a small glass window.  From the video, the window looks to be about the size of an adult’s head and situated at head level.  The thief smashed through window, reached through, and unlocked the door.   This event affected the more than 600 students that were enrolled into the MORE–Minority Opportunities in Research–program, as well as faculty members.  Social Security numbers and addresses were part of the sensitive information saved on these computers.

In the 1980s, at the onset of widespread computer technology, I worked my way through college as a campus security guard and got involved in helping to troubleshoot some early hacking attempts.  But back then computers were heavy and had to be directly wired to the mainframe – so we had the advantage in tracking down the perpetrators.  Today – with wireless and mobile computing the advantage goes to the thief – unless universities start to learn to use modern security tools like Alertsec’s disk drive encryption.

Thief Brags on Facebook – Using the Stolen Laptop

September 1st, 2009

facebookThis story highlights what disk encryption is all about.  We hate to make light of somebody’s misfortune but this example is humorous, sad and educational all at the same time.  We so often hear about the risks of personal data that is on a stolen laptop being used and this tale shows how it actually can be used.  We even thought about whether we should include her name – but it is already as public as public can be!

So here is the story – and yes you will laugh (and feel guilty):  In August, Victoria Richardson, from East Sussex in the United Kingdom, had her home burgled.  She lost an iPhone, a Nintendo DS games console, a handbag containing a purse, cash and debit cards and a black Toshiba laptop. And yes, her laptop was as unsecure as it could be.  No passwords and certainly no disk drive encryption – something that could have prevented the following embarrassment.

Not only did the criminal steal the laptop, but the thief logged into the victim’s Facebook account.  Victoria later logged into her Facebook account (using some other computer) and discovered that the thief had left several messages on her account. They read:

“on my new laptop”

“Listening to music on my new phone feels so good.”

“I have the laptop , phones ok but a bit scratched itll do, tv was rubbish so I left it, ds was a bonus, now to the porn shop, thankyou toshiba is my favourite make”.

“regards your night time burglar”.

So without anything to secure the laptop, this unfortunate woman not only had her physical space invaded but also had her online space taken over! As Ms Richardson put it: “I felt very spooked. I have never felt like that before. It felt like they were rubbing my nose in it.”

Most article noted that while these Facebook messages prove that the thief is quite stupid. Leaving traces of his/her activity on a social networking site can only help the police trace them and bring them to justice.  However, in the end that does not sound like the case as the police are still looking for the criminals.

We don’t mean to add insult to Victoria’s injury, but if even just a few folks learn from this event and implement hard disk encryption at home or at their business, then maybe some good will come from Victoria’s hassles.  Encryption can’t prevent the physical loss – but it can prevent the additional invasion of your online space!
