Open a newspaper, turn on the TV, head online for your daily dose of news, and there’s one subject that’s impossible to escape. And surprisingly, it’s nothing to do with a blonde, British Prime Minister. Instead, the tensions between Russia and Ukraine have taken over, with minute-by-minute news and commentary being relayed to us. As if the prospect of war…
Nexus Industrial Memory specialises in the provision of memory-based products designed especially for applications where commercial solutions are simply not secure enough, rugged enough or have no guaranteed long-term availability. Nexus Industrial Memory will be showcasing some of the electronics industry’s most secure embedded memory solutions on stand C75 at Southern Manufacturing & Electronics on 8-10th February in Farnborough and…
IoT-enabled devices used in industrial applications are vulnerable to many forms of cyberattack. Michael Barrett, managing director of Nexus Industrial Memory, outlines some ways in which devices might be attacked and suggests how they can be made more secure. Security is a growing concern for the IoT and its industrial counterpart (the IIoT) so I won’t recount any numbers,…
In an earlier blog I discussed how embedded memory might be attacked through a forced memory buffer overflow, and I indicated how to protect against such an attack. However, while the countermeasures I suggested are relatively simple ones, certainly at the engineering level, there are other methods of attack which are harder to thwart. Also, the bigger picture of implementing…
With more and more operational technology systems becoming IoT-enabled, the attack surface for cyberattacks is getting larger. Michael Barrett, Managing Director of Nexus Industrial Memory, discusses threats and solutions. In the world of consumer electronics, the internet of things (IoT) provides authorised users with remote access to a wealth of smart appliances. Similarly, the industrial IoT (IIoT) provides authorised users…
For many applications data collected in the field must be stored onto removable memory devices. Michael Barrett, MD of Nexus Industrial Memory, provides guidance on what to look for when selecting a drive for use in harsh environments. Data logging is at the heart of condition monitoring which, in the industrial sector, for example, is at the heart of predictive…
IIoT-enabled operating technology (OT) embedded systems are exposed to risks from the moment their comms ports open. In this blog we’ll ask and answer the question ‘How might an embedded system be attacked?’ by considering the two common types of attack. Historically, embedded systems have been relatively secure. To steal data or install a rogue program, a hacker would need…
SSDs are increasingly popular as a method for storing data, but they also open up the risk of cyberattacks. Secure erasing them is ideal for optimising PC performance, but also necessary for critical applications in case of attacks or data breaches. Thanks to an innovation from Flexxon, not only this security problem, but also multiple other issues created by using…
The modern world is heavily data-oriented and is reliant on technology that provides easy, fast and secure access to high volumes of data. In the past, hard disk drives (HDDs) were relied on for storage. Increasingly, Solid-State Drives (SSDs) are used. They provide much faster access than HDDs and, as they have no moving parts, reliability is much higher. Solid…
As Coronavirus COVID-19 continues to challenge our industry it’s important we don’t lower our guard against digital viruses. Michael Barrett, MD of Nexus Industrial Memory, explains how ‘going industrial’ can improve the security of applications that use removable memory devices. Cybersecurity is a growing concern in all sectors and the electronics industry is considered particularly at risk because it comprises…
