Compliance in Kubernetes
Regulatory compliance is no longer optional for organizations running production workloads on Kubernetes. Whether you're handling financial transactions (PCI-DSS), healthcare data (HIPAA), or providing SaaS services (SOC2), your Kubernetes infrastructure must meet specific security and operational requirements.
The good news is that many compliance controls overlap, and with the right approach, you can satisfy multiple frameworks simultaneously.
Understanding the Frameworks
SOC 2
Service Organization Control 2 focuses on five trust service criteria:
- Security — Protection against unauthorized access
- Availability — System uptime and performance monitoring
- Processing Integrity — Accurate and complete data processing
- Confidentiality — Protection of sensitive information
- Privacy — Personal information handling
For Kubernetes, SOC 2 primarily concerns itself with access controls, audit logging, and change management.
HIPAA
The Health Insurance Portability and Accountability Act applies to organizations handling Protected Health Information (PHI). In Kubernetes environments, HIPAA requires:
- Encryption of data at rest and in transit
- Access controls and audit trails
- Regular risk assessments
- Incident response procedures
PCI-DSS
The Payment Card Industry Data Security Standard applies to organizations handling credit card data. Key Kubernetes requirements include:
- Network segmentation and access restrictions
- Vulnerability management and patching
- Logging and monitoring of all access
- Regular security testing
CIS Kubernetes Benchmark
The CIS (Center for Internet Security) Kubernetes Benchmark provides over 200 security controls organized into categories:
- Control Plane Components
- etcd Configuration
- Control Plane Configuration
- Worker Nodes
- Policies (RBAC, PSP, Network Policies, Secrets)
Automating Compliance
Manual compliance checks are error-prone and time-consuming. Automate your compliance posture with these strategies:
- Continuous Scanning — Run CIS benchmark checks on every cluster change, not just quarterly
- Policy Enforcement — Use admission controllers to prevent non-compliant resources from being deployed
- Audit Trail — Maintain immutable logs of all cluster changes for auditor review
- Evidence Collection — Automatically generate compliance reports with screenshots and data exports
Mapping Controls to Frameworks
Many CIS controls map directly to compliance framework requirements:
- CIS 1.2.1 (API Server auth) maps to SOC2 CC6.1, HIPAA 164.312(d), PCI-DSS 8.2
- CIS 4.2.1 (Kubelet auth) maps to SOC2 CC6.3, HIPAA 164.312(a)(1)
- CIS 5.2.1 (Pod Security) maps to SOC2 CC6.8, PCI-DSS 2.2
