SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides vulnerability scanning, image hardening, and CIS benchmarks for container security.

Core Features & Use Cases

  • Vulnerability Scanning: Trivy for images and config.
  • Image Hardening: non-root users, read-only FS, minimal base images.
  • Secrets Management & CIS Benchmarks: secret handling and compliance.

Quick Start

Run a Trivy scan on your Docker image and harden the resulting Dockerfile.

FAQPage Schema
How do I scan Docker images for vulnerabilities?

Vulnerability scanning identifies security issues in container images using tools like Trivy. Run Trivy against your Docker image to detect exposed vulnerabilities, misconfigurations, and secrets before deployment to registries or Kubernetes environments.

What's the best way to harden a Dockerfile for security?

Image hardening reduces container attack surface by enforcing non-root users, read-only filesystems, and minimal base images. These practices eliminate unnecessary privileges and limit what an attacker can access or modify inside the running container.

How do I ensure containers meet CIS benchmark compliance?

CIS benchmarks define security standards for container configurations. Audit your images and runtimes against these benchmarks to verify compliance, then apply hardening controls and policy-based rules to close gaps and maintain security posture.

Can I integrate container scanning into CI/CD pipelines?

Yes. Container scanning tools integrate directly into CI/CD workflows to automatically audit images during builds and prevent vulnerable or misconfigured containers from reaching registries or production deployments.

How do I handle secrets in container images?

Secrets management prevents credentials and sensitive data from being embedded in container layers. Scan images for exposed secrets, use environment variables or secret stores, and apply policies to detect and block secret exposure before containers run.

Does container hardening work with Kubernetes deployments?

Yes. Hardened images and runtime protection apply across development, registries, and Kubernetes. CIS benchmark compliance and policy-based controls enforce security standards across the entire container lifecycle in orchestrated environments.
