Securing the industrial internet

GE’s acquistion of Wurldtech is another example of just how seriously engineering companies are taking security in the internet of things, hopefully those building consumer systems are paying attention too.

One of the big concerns with connecting devices to the public internet is security, particularly when equipment that was never intended to be on the net is suddenly wired up.

When the world’s computers started to be connected to the Internet in the mid-1990s it became apparent very quickly that most of the operating systems then in use were hopelessly vulnerable to security problems.

The worry is the same thing will happen today with the Internet of Things, particularly with household equipment which – if the PC industry’s experience is anything to go by – will open up whole new fields of risk to homeowners.

While having your kettle or home networked hacked could be painful, it’s nothing compared to the risks of infrastructure or vital equipment being compromised.

So GE’s acquisition of security company Wurldtech is an important development as it focuses on the software aspects of its products and the Industrial Internet – GE’s own term for the internet of things.

Techcrunch’s Ron Miller has a good run down on GE’s purchase of Wurldtech where Neil McDonnell, the CEO of the acquired business, describes the company’s two pronged approach to security.

First, they do testing to discover vulnerabilities in the system and they certify sites that are secure. Secondly, they provide specific security solutions around a system such as a substation or pump.

For GE, Wurldtech will help them secure existing infrastructure and equipment that’s being connected to the net, what they learn should also help designers of the next generation of equipment build security into their products.

GE’s acquistion of Wurldtech is another example of just how seriously engineering companies are taking security in the internet of things, hopefully those building consumer systems are paying attention too.

Heartbleed, kettles and design – ABC 702 Mornings

The Heartbleed bug and the connected kettle are the topics of today’s 702 Sydney segment with Linda Mottram

This morning from 10.20am on 702 Sydney I’m talking to Linda Mottram about the Heartbleed bug, connected kettles and dropping off the grid. It’s crowded twenty minutes and I’m not sure how much we’ll cover.

Heartbleed is the main topic of the segment and it’s a big issue that not only exposes a weakness in secure computing but also points out problems with the Internet of Things and the open source model of developing software.

One of the quirky stories of the last few weeks has been the iKettle, a connected kitchen appliance. Do we need one and what happens to your cup of tea if the internet drops out.

3D printing is changing the world of manufacturing but designers are now looking at 4D printing, what is it and how might it change the world of design.

If we get time we’ll also look at the possibilities of dropping off the all seeing grid with the story of a security researcher who tried to hide her pregnancy from the Internet.

We’d love to hear your views so join the conversation with your on-air questions, ideas or comments; phone in on 1300 222 702 or post a question on ABC702 Sydney’s Facebook page.

If you’re a social media users, you can also follow the show through twitter to @paulwallbank and @702Sydney.

Bleeding hearts and internet security

No technological revolution is simply or without problems, securing information is one of the great challenges of today’s revolution and Heartbleed is a reminder of that.

The big tech news story of the last two days has been the Heartbleed security flaw, that might have compromised users’ passwords and other details.

Given the nature of the bug where a server can tricked into giving away bits of what’s stored in its memory, it’s hard to say exactly what has been compromised – on most sites you’d be very unlucky to have your password on banking details in the system at the precise millisecond a malicious attacker exploited the bug – but the risks are still real.

While webmasters and system admins around the world are frantically patching their systems, for the average user the best advice is to wait before changing your passwords as if the bad guys already have your details you’d have probably used them by now and changing your logins on a vulnerable server might actually increase the risk of crooks stealing your information.

The Internet of Things

The longer term risks with Heartbleed are actually in embedded systems and the Internet of Things; many systems will have hard coded implementations of the buggy software which may never be patched and these devices may be give up much richer data than a web server would.

It’s another illustration of how difficult the task of keeping embedded technologies up to date and how to secure the Internet of Things.

Open source blues

While there’s no shortage of similar security lapses in commercial software, the Heartbleed saga is going to concentrate the minds of open source community on how to tighten peer review and audit version updates.

Most open source projects are staffed by small groups of time poor volunteers, making auditing and quality control harder. That key parts of the internet and computer industries rely on these underfunded, and often unappreciated groups is a weakness for the entire sector.

No technological change is simple or without problems and securing information is one of the great challenges of today’s tech revolution and Heartbleed is a strong reminder of that, hopefully we’ll learn some lessons about building robust systems.

Windows XP and patches

The Heartbleed security certificate bug is an illustration of how tough life is going to become for Windows XP users in the near future.

It’s notable that the long flagged end of Microsoft’s support for Windows XP happened the day before the Heartbleed bug, one of the most worrying security flaws we’ve seen was publicly revealed.

One of the questions that has bugged many of us in the industry – pardon the pun – is whether Microsoft would back down on its insistence they would not issue security patches for Windows XP when a major exploit became public.

With between 15 and 30% of the world’s desktop computers still running XP and  6,000 websites  reportedly running on the superseded system, it’s hard not to see how Microsoft could justify not sending out an update should an exploit the size of the Heartbleed bug become apparent.

As it is, there may be some argument for updating some of the security certificates in the Windows XP and the older versions of Internet Explorer in the light of the Heartbleed bug, we’ll wait to see on that.

While Heartbleed doesn’t directly affect Windows XP computers, it’s still a reminder that life is going to get tough for those running an unpatchable operating system.

Can the community secure the Internet of Things?

Can the community secure the internet of things? Cisco’s Christopher Young believes so.

As more devices become connected Cisco Systems hopes the security issues can be addressed by the developer community.

“The Internet of Everything is not only turn every company into a technology company but its going to force every company to truly become a company that delivers security,” says Christopher Young, Senior Vice President of Cisco’s Security Business Group.

Speaking at the Australian Cisco Live! Conference in Melbourne today, Young described how business is going to have to change the way it treats the data it collects from sensors.

“Not just in consumer security,” continues Young. “If I’m using technology or I’m delivering a service that’s leveraging technologies like cloud or connected devices and creating information about individuals or organisations through these connected devices then a consumer or enterprise is going to expect a level of security.”

Young sees three major ways that security is becoming more challenging for organisations; changing business models, a dynamic threat landscape and increasing complexity.

The latter point is the area that focuses many executive’s attention in Young’s experience with audiences he speaks to nominating complexity and fragmentation as their greatest concern.

“They get so many products and so many devices and so many tools and so much complexity they really don’t know, in so many cases, where to focus their efforts.”

Young cites Cisco’s Chief Security Officer, John Stewart, that the most fundamental security defence is getting the basics right.

Earlier this year at the release of the company’s 2014 security report, Stewart spoke to Networked Globe on how businesses are struggling with the complexity they face.

“Even the most sophisticated and well funded security teams are struggling to keep on top of what’s happening,” Stewart said.

This problem ties into the other areas that Young identifies, particularly the ‘industrialisation’ of the malware world.

“We have more well funded, more innovated, more determined adversaries than we’ve ever had as an industry.

“It used to be some high school kid in his room trying to infect a bunch of machines with viruses or some guy from Nigeria sending you an email asking you for a hundred bucks and he’ll give you a thousand bucks later.

“The world we live in today has nation states and criminal syndicates and very well funded, very sophisticated attackers so hacking has become an industrialised activity.” Young says, “here’s supply chains involved, there’s support agreements written; the bad guys will even sell each other a contract.”

Young’s views echo those of Sophos Labs’ Vice President Simon Reed who said last year that “now there’s money involved, there’s serious effort, the quality of malware has gone up.”

Part of the solution Young sees involves getting the community involved which is the motivation behind the Cisco Security Challenge announced last week.

“You can only just guess and imagine what all the different security challenges will look like in a world that’s just starting to get formed.”

“Let’s get the community involved in trying to solve some of the problems that we know are going to be inherently introduced by IoE.”

Using data laws to create an economic advantage

Will the EU data laws give European business a competitive advantage?

Yesterday I posted piece on Business Spectator about Australia’s new privacy regulations, little did I know that the European Union Parliament was about to release its own.

The EU regulations look interesting and certainly seem on  first look to be far more comprehensive than Australia’s effort that I describe as a toothless, box ticking exercise.

A notable aspect of the EU’s announcement of the new rules is its claim that the updated regulations are expected to generate €2.3 billion in economic benefits each year.

Whether the EU’s rules prove to be an economic cost – as Australia’s effort will almost certainly turn out to be – or a competitive advantage remains to be seen, however the European Parliament is certainly making a case for data security and privacy protection as being an important selling point in a highly competitive digital world.

The competitive advantages between countries and continents in the 21st Century will be vary different to those that determined the economic winners of the previous two centuries.

Accountability and security

Experian’s massive data breach shows why we, and our governments, have to start taking security seriously.

Security writer Brian Krebs has followed up last year’s story that US credit reporting agency Experian had been selling personal data to Singaporean based identity thieves with the guilty plea from the scheme’s architect.

Krebs points out that the leader of the identity thieves, Vietnamese national Hieu Minh Ngo, could access up to 200 million consumers’ records.

It’s almost impossible to say how much theft, fraud and misery was inflicted on innocent Americans who had their personal details misused by Ngo’s customers.

The amazing thing is it appears that Experian’s executives or shareholders will not suffer any sort of penalty – civil or criminal.

In an age where companies are collecting masses of data on everyone, it’s inconceivable that those trusted to store and protect that information – particularly credit reporting agencies – seem beyond any accountability for failing in their core responsibilities.

There’s also the aspect of undermining the US credit system; if merchants and consumers find they can’t trust credit reporting agencies, then offering or getting credit becomes far more difficult and risky.

Until the management of companies like Experian are held accountable for their incompetence, any talk of safeguarding privacy is empty. It’s why we should treat claims that our data is held safely by government agencies or businesses with a great deal of caution.
