Embedded memory must be secured to protect data from unauthorised access, made by hackers with the intent of stealing or corrupting it.  Click above to read our detailed guide to securing your embedded memory.

SSDs are increasingly popular for storing data, but they 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. Find out how this security problem and other issues created by using an embedded SSD can be eliminated by reading our guide.

NAND flash is a common type of non-volatile memory (NVM). Unlike a volatile memory type, such as DRAM, NAND flash retains data when power is removed and so has many applications. But what is NAND memory and how does it work? In this guide we will explore everything you need to know.

This popular memory type is architecturally optimized for high-density data storage. There are two grades of NAND, consumer and industrial – with the latter having an operating temperature of -40 to 85^oC and suitable for harsh environment applications.  Consumer grade, which has an operating temperature of 0 to 70^oC, is typically found in consumer electronics, and we’ll discuss both types in this guide.

In an earlier blog I discussed the security challenges for embedded memory and stressed that making products, such as IoT-enabled devices, more secure should be taking a much higher priority than it currently is. And in another blog, I outlined how embedded memory might be attacked and offered some simple solutions. Now, it’s time to discuss how to secure embedded…

One key focus for the majority of engineers is Security. And these days it’s even more of a danger, with threats increasing in number and sophistication.

If you design embedded systems, and security is at the forefront of your mind, you’ll find our latest blog useful.  In it we discuss:

• Exactly how your embedded system might be attacked
• How IIoT can make embedded systems more vulnerable
• The two most common types of embedded system attacks
• Two recent embedded system attacks and what we can learn from them

In an previous 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 which is discussed here.

There is a security risk inherent in using removable memory devices such as USB Sticks. The wide availability of USB drives makes them attractive to hackers and an ideal vehicle for introducing malware into a company from within its IT Firewall. Read in our technical blog how moving to industrial removable memory devices could make your environment cyber safe

Powerloss protection (PLP) protects your local system from experiencing data corruption or loss, in turn reducing the risk of corrupted data being stored.  To get the full story on PLP and decide whether it could be valuable for you, have a read of our technical blog

Flexxon X-PHY really is incredibly effective against ransomware attacks, as you can see from this video – – but it’s also equally brilliant at counteracting physical threats. 

If you’d like a live demonstration contact us and we’ll arrange one for you either live or via zoom.

To ensure your data is completely gone, you need to securely erase your SSD.  While this can be done in a variety of ways, traditional third-party services for secure erase come with a series of pain points. this technical blog explores the various solutions for securely wiping sensitive data.

Professional Cyber Security expert states “No threat can get past the X-PHY SSD”, read Flexxon’s exclusive interview to find out how the X-PHY fared against rigorous independent testing.
