Minimal Kernels, Reduced Attack Surface, and Why Linux Optimization Still Matters

"While minimal kernels cannot prevent every vulnerability, reducing attack surface by removing unnecessary kernel features, drivers, and services can proactively mitigate many classes of security issues and reduce exploitability." For a long time, Linux optimization work was seen mostly as a performance exercise. Faster boot times. Smaller images. Lower RAM usage. Better cache behavior. But over the years, something interesting became increasingly obvious: Optimization and security are often deeply related. ...
