Container Security - OWASP Top 10

1. Introduction

Container security is a critical aspect of modern software development and deployment strategies, particularly in cloud environments. This lesson focuses on the vulnerabilities associated with containerized applications and provides insights on how to secure them effectively.

2. Key Concepts

3. Best Practices

1. Use minimal base images to reduce attack surface.
2. Regularly update and patch container images.
3. Implement role-based access control (RBAC) for container orchestration.
4. Scan images for vulnerabilities before deployment.
5. Enforce network segmentation and least privilege access.
6. Log and monitor container activity for anomalies.

4. Code Examples

Below is an example of how to scan a Docker image for vulnerabilities using trivy:

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock \
    aquasec/trivy image --severity HIGH,CRITICAL myapp:latest
