CVE Monitoring & Management: Timesys’ Akshay Bhat Offers Security Guidance for Embedded Open Source Systems Part 2
As discussed in last week’s posting, central to the device maintenance process and keeping devices secure after they’ve been deployed is the ongoing monitoring and managing of CVEs that affect your product components. Therefore, it’s essential to have a clear view of relevant CVEs because there are many moving parts that need to be managed.
Adam Boone: Along those lines, you mentioned monitoring patches and software upgrades as one of the moving parts to be managed in a security maintenance program. What’s the challenge there?
Akshay Bhat: Patch management alone is always challenging, especially if you have a large number of open source components. You need to evaluate when to apply a patch, how the patch affects other components, what testing needs to be conducted, whether a patched component can be backported to earlier versions, and so on.
