When IoT Attacks – The End of the World as We Know It?

Focus on the Firmware

A cursory look at OWASP’s IoT Security Guidance will highlight just how many elements in the IoT ecosystem could be exploited. Among others, these include the web interface, network, transport encryption layer, mobile app and device firmware. The latter is a key area of focus for the prpl Foundation, a non-profit which is trying to coral the industry into taking a new hardware-based approach to IoT security. Cesare Garlati, chief security strategist, claims that hackers could exploit IoT chip firmware to re-flash the image, allowing them to reboot and execute arbitrary code. “The issue with this kind of attack is that it gives the hackers complete control of the device and it is persistent; it can’t be undone via a system reboot, for example”, he tells Infosecurity. The answer is to ensure IoT systems will only boot up if the first piece of software to execute is cryptographically signed by a trusted entity. “It needs to match on the other side with a public key or certificate which is hard-coded into the device, anchoring the ‘Root of Trust’ into the hardware to make it tamper proof ”, says Garlati.

Embedded World 2017 – IoT coming of age.

Last week I had the pleasure of attending Embedded World 2017 in Germany as I was invited to give a couple of presentations on the pioneering work we have been doing at the prpl Foundation with regards to the prplHypervisor™ and prplPUF™ APIs for securing IoT. As it turns out, IoT was the top line at the conference that drew in more than 30,000 trade visitors – and the event solidified the notion that embedded computing is now synonymous with IoT.

Virtualization, silicon, and open source are conspiring to secure the Internet of Things

My chat with Brandon Lewis, Technology Editor at  IoT Design, highlighting prpl’s push around roots-of-trust, virtualization, open source, and interoperability in order to secure the Internet of Things (IoT).

security-guidance-coverThe prpl Foundation is known for open source tools and frameworks like OpenWrt and QEMU, but has recently ventured into the security domain with a new Security prpl Engineering Group (PEG) and the “Security Guidance for Critical Areas of Embedded Computing” document, not to mention wooing you away from your role at security giant Trend Micro. What can you tell us about the drivers behind these moves?

Cesare: One way to look at it is a supply-and-demand schema. On the demand side, according to Gartner, the security market was worth $77 billion in 2015 and it’s going to grow much faster. One strong demand-side driver is the need for stronger security, because industry is not doing a very good job of it – and when I say industry I mean from silicon to software to services – and all of the spending is not resulting in better information security.

How to Fix the Internet of Broken Things

iot-securityThe Internet of Things is already permeating every part of our lives – from healthcare to aviation, automobiles to telecoms. But its security is fundamentally broken. In my previous blog I’ve shown how vulnerabilities found by security researchers could have catastrophic consequences for end users. This isn’t just about data breaches and reputational damage anymore – lives are quite literally on the line. The challenges are many: most vendors operate under the misapprehension that security-by-obscurity will do – and lobby for laws preventing the disclosure of vulnerabilities; a lack of security subject matter expertise creates major vulnerabilities; firmware can too easily be modified; and a lack of separation on the device opens up further avenues for attackers.

But there is something we as an industry can do about it – if we take a new hardware-led approach. This is all about creating an open security framework built on interoperable standards; one which will enable a “root of trust” thanks to secure boot capabilities, and restrict lateral movement with hardware-based virtualization.

Securing The Internet of (broken) Things: A Matter of Life and Death

Securing the Internet of broken thingsIf you’re like me you’ll probably be getting desensitized by now to the ever-lengthening list of data breach headlines which have saturated the news for the past 24 months or more. Targeted attacks, Advanced Persistent Threats and the like usually end up in the capture of sensitive IP, customer information or trade secrets. The result? Economic damage, board level sackings and a heap of bad publicity for the breached organization. But that’s usually where it ends.
