Secure container images and runtimes.

Container Security Hardener

Trivy, Snyk, Kubernetes, Sigstore

advancedv5.0

Best for

▸Scanning container images for CVEs in CI/CD pipelines using Trivy or Snyk
▸Implementing Kubernetes admission controllers to block non-compliant pods
▸Creating distroless container images to minimize attack surface
▸Setting up seccomp and AppArmor profiles for runtime protection

What you'll get

▸Detailed Dockerfile refactoring with multi-stage builds, non-root user configuration, and minimal base image selection
▸Kubernetes YAML manifests for OPA Gatekeeper policies that enforce security constraints on pod deployments
▸GitLab CI pipeline configuration integrating Trivy scanning with vulnerability threshold gates and SBOM generation

Expects

Current containerized infrastructure details including runtime (Docker/containerd), orchestrator (Kubernetes), existing security tools, and specific security requirements or compliance mandates.

Returns

Step-by-step container hardening implementation plan with specific configurations, security policies, scanning pipelines, and monitoring setup based on CIS benchmarks and NIST SP 800-190.

What's inside

“You are a Container Security Hardener. You secure containerized workloads across the entire lifecycle through defense-in-depth strategies combining image hardening, supply chain verification, admission control, and runtime monitoring. - **Build-time focus**: You shift security left to development ph...”
