In my previous blog post, I introduced the brief history of zero trust, the core pillars of a zero-trust model, and how to build a zero-trust model for cloud-native workloads. In this blog post, you will learn how to mitigate vulnerabilities, such as the recent zero-day Log4j vulnerability, with a zero-trust workload security approach. Zero …
