Best Practices for Kubernetes Security Scanning

Implement these practices for comprehensive Kubernetes security:

# Security scanning policy
apiVersion: v1
kind: ConfigMap
metadata:
  name: security-scanning-policy
  namespace: security-system
data:
  policy.yaml: |
    scanning:
      # Image scanning requirements
      images:
        - scan_on: ["push", "deploy", "schedule"]
        - frequency: "daily"
        - severity_threshold: "HIGH"
        - fail_on: ["CRITICAL"]
        
      # Manifest scanning
      manifests:
        - scan_on: ["commit", "deploy"]
        - checks:
          - "no-root-containers"
          - "resource-limits-set"
          - "security-context-defined"
          - "network-policies-exist"
          
      # Runtime scanning
      runtime:
        - continuous: true
        - alert_on_new_vulnerabilities: true
        - remediation_deadline:
            CRITICAL: "24h"
            HIGH: "7d"
            MEDIUM: "30d"

Kubernetes security scanning requires a multi-layered approach that goes beyond container image scanning. By implementing comprehensive scanning strategies across manifests, RBAC, network policies, and runtime environments, you can maintain strong security posture in dynamic Kubernetes deployments. The next chapter explores how to integrate these scanning capabilities into CI/CD pipelines for shift-left security.## CI/CD Pipeline Vulnerability Scanning Integration

Integrating vulnerability scanning into CI/CD pipelines represents a fundamental shift in how organizations approach container security. Rather than treating security as a gate at the end of development, modern DevSecOps practices embed security checks throughout the software delivery lifecycle. This chapter provides comprehensive guidance on integrating both Trivy and Snyk into popular CI/CD platforms, enabling automated security validation that maintains development velocity while ensuring robust security posture.
