Built-In Security for the Internet of Things


With the number of devices being connected to the Internet increasing daily, bringing the vision of the Internet of Things (IoT) or Internet of Everything (IoE) to reality, we hear about securing the IoT with almost the same frequency.

The reality is that securing the disparate ‘things’ is going to be a real problem; one certainly can’t use traditional enterprise and network security methods like anti-virus, as the things are not all running the same operating system (if an operating system is used at all), and the likely types of cyber threats will be very targeted to the specific system being attacked, which really nullifies any AV like approaches. Network protection is not any easier, as most of the networks that things are connected […]

Now Any Embedded System Can Be Hi-Reliability


The distinction between ‘hi-reliability’ and ‘standard’ embedded software design is being blurred as the commercial and human consequences of embedded system failure escalate. Whether in avionics, medical, automotive, or SCADA systems, the slightest flaw can ripple down to a system failure and potential injury or loss of life.

Technology integrated into these systems must be highly scrutinised to ensure system reliability is preserved. While robustness is a primary concern, these systems are constantly evolving to increase functionality, reduce footprint, and save operational cost.

In order to meet these demands systems become more software intensive and more complex, making robustness difficult to achieve.

At the same time, the increasingly connected world of commercial embedded systems leaves them vulnerable to threats from the outside, leading to increased demand […]
