Developed comprehensive compliance baseline support for KylinSec Server V6 within the ComplianceAsCode/content repository, focusing on integrating new product definitions, SCAP mappings, and OVAL rules. Leveraged Python, CMake, and YAML to wire the baseline into the existing build system and CI/CD pipeline, enabling automated validation and improving reliability. Adapted platform-specific security controls, including PAM faillock, IPv6 sysctl, emergency target authentication, SSH key exchange, and KASLR, to ensure enforceable compliance. Established reusable content patterns to streamline future baseline development for KylinSec platforms. The work enhanced infrastructure automation and security validation, reducing manual effort and accelerating compliance verification.
