How to Layer Secure Docker Containers with Hardened Images

Containerized applications are becoming increasingly popular for enterprises due to their portability, faster application launches, and high efficiency. However, using innovative solutions like Docker containers also comes with increased risk. Therefore, it’s crucial for cloud security professionals to consider secure container environments and the use of hardened images to mitigate the risk. In this article, we’ll provide guidelines on how to layer secure Docker containers with hardened images.

How to Layer Secure Docker Containers With Hardened Images

Secure Docker containers provide a cost-effective, flexible, and easy-to-use solution for enterprises. DevOps and testing processes are also more streamlined with quick build and test applications. Additionally, containerized applications are easily interchangeable, providing greater convenience.

The Center for Internet Security (CIS) offers several layered hardened images in secure Docker containers, such as Amazon Linux, Ubuntu Linux, NGINX, and PostgreSQL, among others. These containers are easy to deploy and patch, cost-effective, and lead to compliance with various regulatory frameworks like HIPAA or NIST.

Final Words

Docker container images should always be hardened to create a secure base image suitable for a specific environment. This process actively looks for known vulnerabilities and updates packages to ensure a secure environment. By layering secure Docker containers with hardened images, you help mitigate the risk of potential cyber threats to your cloud workloads, improving the reliability and safety of the system.

FAQs

1. Why are secure Docker containers important?

Secure Docker containers are essential as they provide a reliable and safe environment for cloud workloads. By using hardened images to create a secure base image for an environment, you help mitigate the risk of potential cyber threats. Good container security practices are a necessity in the current digital landscape.

2. What are the benefits of using secure Docker containers with hardened images?

Secure Docker containers with hardened images provide cost-effectiveness, flexibility, ease of use, quick build and test applications, and interchangeability of containerized applications. Additionally, the containers offer protection against malware, insufficient authorization, and remote cloud intrusion.

3. What is CIS?

The Center for Internet Security (CIS) is a nonprofit organization that provides cybersecurity solutions for preventing and responding to cyber threats. CIS offers several layered hardened images in secure Docker containers to help organizations work safely and affordably in the cloud.

4. How can I create hardened images of Docker containers?

The process of creating hardened images of Docker containers involves updating packages and actively looking for known vulnerabilities. Once this hardening process is complete, a new base image is created, which can be safely used in pipelines. It’s always a good idea to consult the latest recommendations from CIS to stay on top of best practices.
