Kubernetes hardening: Drilling down on the NSA/CISA guidance
NSA/CISA Kubernetes hardening guidance offers a solid foundation for securing Kubernetes environments. Here are the key components and why they're important.
Kubernetes has become the de facto choice for container orchestration. Some studies report that up to 88% of organizations are using Kubernetes for their container orchestration needs and 74% of that occurring in production environments. That said, security remains a critical concern with as many as 94% of organizations reporting at least one security incident in their Kubernetes environments in the last 12 months.
As organizations continue to adopt Kubernetes, it is crucial that they follow industry best practices and guidance to ensure they are using Kubernetes securely. One great resource is the Kubernetes Hardening Guidance recently published by the US National Security Agency (NSA) and Cybersecurity and Infrastructure Security Agency (CISA).
