Knowing what we don’t know

Cisco’s 2016 security report show businesses are more uncertain than ever about their network defenses. This is a good thing.

The 2016 Cisco Security report is in many ways an encouraging document, while it describes a litany of threats facing the modern business the fact managers are less confident about their defenses is a good thing.

Of the 2432 security executives surveyed 59% claimed their security infrastructure was up to date against 64 percent said the same. Acknowledging this is motivating them to improve their defenses.

For industry, the real concern is the small business sector where there’s a clear decline in the use of IT security tools. As the Target breach showed, trusted contractors and suppliers provide a weakness in an organisation’s systems that malicious actors are keen to exploit.

In Cisco’s analysis, the main reasons for SMBs lack of concern is their belief they are too small to be valuable to hackers and most of their IT management is outsourced.

A shift to the cloud shouldn’t be understated, particularly given many SMBs are shifting their IT functions onto cloud services. While this doesn’t fully protect businesses, the cloud providers certainly offer a far higher level of protection that the local plumbing contractor relying on a mom and pop computer support service.

The bad guys however are responding to that shift with Cisco reporting increased browser based and DNS attacks, both of these are useful in compromising cloud computing services which means both service providers and end users have to be vigilant about security.

At all levels of business though the lack of confidence in security has major ramifications as the Internet of Things is rolled out and common devices start being connected to fragile and often compromised networks.

The good news for vendors like Cisco is this lack of confidence could spur a new wave of business investment as companies improve their network security.

Another important aspect of CIOs and business owners not being confident about their network security is they are far less likely to assume their systems are safe or to passively accept vendor assurances about their safety.

For all of us a customers and users of these technologies, a greater focus on security by the organisations we deal with should be welcomed as well.

Anatomy of an internet exploit

The Angler exploit tells us much about the challenges of internet security

As one does on a weekend, I’m working my way through the 2016 Cisco Security Report.

There are plenty of insights on online security trends which I’ll cover in tomorrow’s blog post but one aspect that sticks out in the report is the case study on the Angler Exploit which takes advantage of hacked domain registrar accounts to create new domain names to serve phishing pages, ransomware sites and malicious advertisements.

Dealing with these sites is a major problem for network administrators and Cisco claims many of the domains registered haven’t yet been used by online criminals.

The Angler exploit shows just how complex internet security has become. The issue of trust is a complex thing and certainly no-one can trust every domain we see. That there are thousands of ‘disposable’ domains available to scammers only makes things more difficult for the average user.

The insecure internet of children’s toys

Security weaknesses in the Hello Barbie show safety is an afterthought rather than a fundamental part of designing tech products.

What could go wrong with an internet connected doll with artificial intelligence that can respond to children’s conversations?

A lot as it turns out.

The Washington Post reports the Hello Barbie has a range of vulnerabilities that could be used to eavesdrop on conversations and potentially carry out even more malicious acts.

Once again we see marketers and salespeople being ahead of the IT and security experts with the security of an Internet of Things device being seen as a bolt of afterthought rather than a basic design consideration.

Designing a secure IoT ecosystem

Ensuring the next generation of IoT devices is secure will be one of the challenges facing the next generations of designers.

Ensuring the next generation of IoT devices is secure and a good citizen of the wider ecosystem will be one of the challenges facing the next generations of designers.

Diego Tamburini, Manufacturing Industry Strategist of design software company Autodesk, spoke to Decoding The New Economy about how the IoT will change the design industry. “We’ve been designing equipment to connect to the internet for a generation,” he said. “What’s changing is that now the addition of software, electronics, networking and communication is breeding into objects that were purely mechanical.”

Melding the physical and software worlds doesn’t come without risks however, something that worries Internet pioneer Vint Cerf who foresees headlines like ‘100,000 fridges hack the Bank of America’ in an interview with Matthew Braga of Motherboard Canada.

Apart from the fact it could be a hundred million, Cerf has good reason to be worried. Most consumer IoT devices are hopelessly insecure and the recent stories of hacked cars only emphasises the weaknesses with connected household items.

Cerf and Braga make the point the ‘I Love You’ worm of the year 2000 became a crisis because the world had reached the point where personal computers were ubiquitous. A similar piece of malware in a world where everything from kettles to wristwatches are vulnerable would be exponentially worse.

These risks put a great onus on product designers, even more so given much of the functionality is based upon those devices communicating with others across the internet and cloud services, something that Tamburini emphasised.

“One important thing that is happening with thing being connected is we are not just designing things that function in a vacuum, we’re increasingly designing members of a larger ecosystem.” Tamburini states, “now we have to think of how the product will have to connect to other products and how they will collectively perform a function.”

Part of that risk is that should those devices malfunction, either deliberately as part of a botnet or malware attack, or accidentally as we saw with the connected home being disabled due to a defective smart lightbulb flooding the network with error messages, then the wider community may be affected in ways we may not expect.

Cerf believes it’s going to take a big, catastrophic hack on a grand, connected scale before a shift in security begins to happen, and before people begin to even consider that such a vulnerabilities even exist.

If that’s the case, it will be that society has ignored the clear warning signs we’ve seen from events like the Jeep hack and the Stuxnet worm, not to mention the massive privacy breaches at Target and Sony. For designers of these systems hardening them is going to be an essential part of making them fit for today and the future.

Apple CEO Tim Cook on Privacy and Profits

Apple CEO Tim Cook discusses privacy, profits and cars with NPR’s All Things Considered

“Privacy is a fundamental human right”. A short, but sweet and fascinating, NPR interview with Apple CEO Tim Cook.

Cook goes onto to avoid discussing the likelihood of Apple Cars and expounds the advantages of repatriating corporate profits back to the US, something we can expect cash rich companies like Apple to start agitating for after the next Presidential election.

The interview, which is only eight minutes long, is well worth a listen as Apple positions itself against competing internet giants Google and Facebook over the topic of privacy.

Experian, T-Mobile and third party security risk

T-Mobile’s security woes at the hands of Experian show trust cannot be outsourced

Another day, another corporate security breach (or six). This time telco T-Mobile has revealed up to 15 million customers’ data has been compromised.

Notable in this story is that T-Mobile are firmly putting the blame on credit monitoring company Experian.

For both companies this is extremely embarrassing with T-Mobile stating, “our vendors are contractually obligated to abide by stringent privacy and security practices, and we are extremely disappointed that hackers could access the Experian network.”

T-Mobile, like most telcos, sees a major opportunity in being a trusted provider of security services and this setback hurts them in a key market.

Experian on the other hand have shown their slack attitude to user data previously, having been caught selling consumer details to identity thieves.

That a company in such a privileged position as Experian can be constantly caught this way will almost certainly increase the push to see penalties for corporate data breaches start to get real teeth and the United States’ cavalier attitude to public privacy and online security will take another dent.

For T-Mobile and most other companies, the lesson is start and clear. Trust starts with your own contractors and business partners, it cannot be outsourced.

Volkwagen shows the IoT’s data weakness

The Volkswagen emissions scandal shows the data weakness in the internet of things

The Volkswagen emissions scandal has rocked the company and cost its CEO his job, but the implications of the company falsifying data to past regulators’ test has serious implications for the Internet of Things.

As the Los Angeles Times explains, Volkswagen designed software to detect when its cars were being tested. During test the software would modify the car’s performance to give a false result.

This is similar to the Stuxnet worm which sent Iranian operators false information indicating the uranium enrichment centrifuges were operating normally when in truth they were running at speeds well outside their design.

Both the Volkswagen fraud and the Stuxnet worm show how software can be used to tell lies about data. For processes and businesses relying on that data, it’s critical to know that information is reliable and correct.

Data is the raw material of the internet of things and all the value derived comes from analysing that information. If the information is false, then there’s no value in the IoT. Designing systems that guarantee the integrity of data is going to be essential as devices become more connected.
