System hardening benchmarksThe information security policy should reference security benchmarks the organization will use to harden mission critical systems, such as the Center for Information Security (CIS) benchmarks for Linux, Windows Server, AWS, and Kubernetes. 12. References to regulations and compliance standardsThe information security policy should reference regulations and compliance standards that impact the organization, such as GDPR, CCPA, PCI DSS, SOX, and HIPAA. 9 best practices for successful information security policies
