So if upstream Yocto or Buildroot has patched a vulnerability, a binary scanner shows it as “unfixed.” Similarly if a vulnerability affected only a driver or a platform not applicable to your product, they would still be reported.

False positives: The metadata (configurations enabled, patches applied, etc.) available in build systems is not part of the binary image.

However, below are the drawbacks of such an approach: This works fairly well where the SBOM and/or build sources are not available. Traditional IT approachīinary scanners: Generate an SBOM by analyzing uploaded target binary images based on file signatures.

With Vigiles, we created open source software to generate an SBOM with vulnerability data that directly integrates with Yocto ( meta-timesys) and Buildroot ( vigiles-buildroot) to address the needs of embedded systems. The two popular build systems supported by semiconductor vendors are Yocto and Buildroot, so your ideal tool of choice should integrate with these build systems. This additional metadata can be used by the vulnerability monitoring tool to reduce false positives by reporting “unfixed” vulnerabilities applicable to “your hardware platform” based on “enabled configurations.” In components like the Linux kernel, this can reduce the number of vulnerabilities by up to 75%, saving you investigation and remediation time. List of vulnerabilities already addressed based on applied patches.

Configurations enabled in the software (e.g., drivers enabled in the Linux kernel).

Build systems have all the information required to generate an SBOM along with additional metadata that can help improve the accuracy of vulnerability reports.

The best option for generating the SBOM is to extract the component information from the build system. There are a few different ways of generating the SBOM as discussed below: Build System based Software Composition Analysis (SCA) tools generate a software bill of materials (SBOM), which is a list of software components installed on your product, and then create a vulnerability report by comparing the components against a known vulnerability list. 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. After evaluating multiple IT cybersecurity tools, we at Timesys ended up creating a vulnerability management tool called Vigiles, which is optimized for embedded devices. 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.
