Bjorn Erik Lomo enhanced security for the navikt/k9-punsj repository by implementing access policy configurations for the K9-los-api application. He focused on strengthening access control and compliance by updating deployment files and production environments within Google Cloud Platform. Using YAML and leveraging skills in Kubernetes and configuration management, Bjorn introduced policy-driven access controls that improved governance and reduced risk in production. His work involved modifying deployment configurations to enforce new access policies across both staging and production, ensuring consistent security standards. Over the month, he delivered targeted changes that addressed security hardening without introducing new features or resolving existing bugs.
