A recent blog post by Kees Cook, a Linux security expert and Google security engineer, illustrates the challenges in maintaining the security of the Linux kernel. One of the main takeaways from the blog is: “If you’re not using the latest kernel, you don’t have the most recently added security defenses (including bug fixes).”
Going the “upstream first” route is the absolute best way of keeping the kernel secure. However, it is only part of the story.
Monitoring and managing vulnerabilities in embedded Linux devices presents a unique set of needs that traditional IT vulnerability tools fail to address and result in wasted efforts chasing false positives and inefficiencies due to cumbersome workflows. After evaluating multiple IT cybersecurity tools, we at Timesys ended up creating a vulnerability management tool called Vigiles, which is optimized for embedded devices. This blog aims to share the lessons learned and how the right tool can bring your security maintenance cost down while improving the security posture of the device.
Best practices for triaging Common Vulnerabilities & Exposures (CVEs) in embedded systems: Top Three Questions Answered

Stop Chasing Vulnerability Ghosts: Why efficient vulnerability detection is essential to medical device security
To detect and correct vulnerabilities, eliminate false positives and prioritize the rest.
Every embedded system device maker should want to make security a selling point, preventing breaches or exploits, not an embarrassment if a security problem occurs. But nothing equals the liability and regulatory risk associated with medical devices.
Reducing cybersecurity risks to medical devices is essential. Regulators like the US Food and Drug Administration (FDA) have made improving medical device security a critical focus in recent years.
This means many in the medical device manufacturing community are now rethinking how the software components of their products are secured throughout their product lifecycles.
This is a summary of a blog post published in full on NXP.com.
Connecting and being connected makes us vulnerable to hackers. With the number of IoT devices forecasted to reach 20.4 billion by 2020, the need for product security becomes even more pressing.
Every week, hundreds of new vulnerabilities are …
