Dangerous appliances
I have long suspected my toaster of plotting against me. Sometimes it fails to make the toast pop up in the hopes that I will stick a fork in the slot and get electrocuted. These days you have to work hard to keep one step ahead of your electrical appliances. I have never worried about my refrigerator, however. But now I am going to monitor it more carefully. Thank your for alerting us all to these threats.

Sounds like an idea for a sequel to Disney's classic, The Brave Little Toaster.

Re: Dangerous appliances
I don't think the Internet of Things movement will play out for consumers for awhile. Seems more of an enterprise/manufacturing/supply chain technology for the time being. But when it does eventually come to kitchens and living rooms, will we rely on Symantec, McAfee and Kaspersky to provide protection software for our refrigerators like we do for PCs? The use of third-party anti-virus software in IoT home situations didn't come up in the article so I was curious.

Re: Dangerous appliances
Shane: I think a slightly different approach is needed to detect malicious code running within embedded devices. Anti-virus is very good a detecting known bad code, and allowing the vast numbers of 'good' software that you could install on a desktop device to run unimpeeded.

An embedded device should only ever run one programme and contain no other software apart from updates. So we would need to establish that only authorised software can run on the device, and that any instructions received by the processor (or any sensors or actuators) has been generated from legitimate code operating correctly.

Its a subtly different problem that requires a different approach.

Re: Dangerous appliances --subtly different problem that requires a different approach.
Martin, I think you hit the nail on the head when you describe the security issues related to the IoT as a "subtly different problem that requires a different approach. I suspect your use of the words "subtly different" is an understatement!   Thanks for raising the issues about the brave new world (let alone toaster) that we are entering, and also your very thoughtful comments.

Re: Dangerous appliances
Quite right! My toaster burnt my toast this morning, probably out of spite. However, my current toaster is entirely mechanical. As the price of computing power keeps dropping computers are finding their way into even the smallest device. Experience tells us that where you have software, you have bugs which can frequently be exploited. Lurking in a cupboard I have a mechanical telephone, its laughable to imagine that this device could contain malware, yet I now have a smart phone on which I can install all sorts of dubious software if I so wish, or if I don't pay attention. With the current pace of technology, I'll be willing to bet that within a few years there will be a smart-toaster in every kitchen.

Hacker: Good afernoon, sir, is your house empty now?
In addition to fearing that hackers will learn my milk is out of date, I would hate for intruders to snoop on our local area network to learn, for marketing purposes or worse, what my family's habits were or when the house was empty. If all the home appliances were on a household network, a great deal of information would become available to hackers, the public utility, the appliance dealership. Martin Lee is right. We don't quite realize what we're getting into here.

Re: Hacker: Good afernoon, sir, is your house empty now?
cbabcok: Like most things in security its a trade off. I don't doubt that there will be many advantages to the Internet of Things. Anything that can help us better manage our limited resources, allow us to do more with less, or even just make less demands on my free time has to be a good thing. Nevertheless, there will be risks. If we can prepare for those risks now and think about how we can manage them, then we can maximise our benefits while minimising any downsides.

Compimise your services?
Let's suppose for a moment that you live in Phoenix. It's July and  109 degrees outside. As a purveyor of ransomeware, I would shut off your refrigerator and air conditioning. I would only require that you pay me $100 in order to restore their services...

Re: Compimise your services?
seppleyt5j01: Exactly, I see this as the biggest risk. We've already seen attackers seeking to distract security teams within the financial services industry by launching a denial of service attack just before attempting to compromise high value systems. Taking malicious control of environmental control systems would be a very effective mechanism of causing disruption to a security team or business.

I hadn't thought of a ransomware style attack on environmental control, but a lack of heating at this time of year, or the a/c set to full heat in the middle of summer would no doubt lead many people to reach for their credit card to pay off their attackers.

Re: Compimise your services?
Maybe a few of just that sort of attacks would make the public finally demand that either the agencies charged with protecting us go on the offensive against those using ransomware in a real and meaningful way, or demand that makers of these appliances get serious about secure application development.

Re the former, the concept of offensive security is not talked about much yet outside security circles. What will it take to bring it into the mainstream?

Re: Compimise your services?
Lorna: I think that by then it will be too late. If we're to secure internet enabled smart-devices we need to ensure that these are secure by design *now*. By the time that such attacks are hitting the headlines, there will already be many thousands of these devices in circulation that we will not be able to secure. We need to raise the profile of security to make sure that buyers are raising the issue with the vendors. In this way we can make security a competetive advantage for manufacturers, in the same way that anti-lock brakes and airbags are for cars.

Like we might look for an EnergyStar label! Maybe there should be an independent lab, like Consumer Reports, testing and certifying security in a way consumers can understand.

Re: Compimise your services?
That's a great point about the scale of the IoT. It's fun to talk about smart toasters, Google glass and all the gee whiz technology that entrepeneurs are imagining for the future. But security-after-the-fact will be a nightmare. On the other hand, how do you defend against attacks on products that haven't yet been invented?

Re: Compimise your services?
Marilyn: The internet of things will happen and it will be awesome. I see there is another article on the business models of IoT by Ido Sarig on Information Week today http://ubm.io/1aPnuye We know how to secure these systems by design, it takes some thought but it is not impossible.  Systems have been succombing to the same attacks again and again since the time of the Trojan wars and the invention of a certain horse. I'd be very happy buying a system that was secure against today's attacks.

Isn't this exactly why John Conner could not break into HQ and destroy Skynet? It had already distributed itself to every toaster and fridge on the plant!

Developing and Testing an Effective Breach Response Plan
Whether or not a data breach is a disaster for the organization depends on the security team's response and that is based on how the team developed a breach response plan beforehand and if it was thoroughly tested. Inside this report, experts share how to: -understand the technical environment, -determine what types of incidents would trigger the plan, -know which stakeholders need to be notified and how to do so, -develop steps to contain the breach, collect evidence, and initiate recovery.
