Helping Organizations to Secure Google Cloud Container Data

Containers, in simple terms, offer a packaging mechanism which lets application to be kept in a different environment in which they actually run, so developers can focus on deployment and management without bothering with internal details such as software versions and configurations specific to the app. Sometimes, containers are compared with VMs, containers allow you to package your application together with libraries and other dependencies, providing isolated environments for running your software services.

Why we need containers?

The reason why you need containers is that instead of virtualizing the hardware devices with virtual machines, the containers virtualize at the operating system level, with multiple containers running on the OS kernel directly. As a result, containers are much more lightweight, because they share the OS kernel, boot much faster and use less memory.

The majority of attacks on containers usually takes place on drives, where the attacker looks for any kind of vulnerabilities.To protect these containers against this kind of attacks is to patch the base image, packages, application code and almost everything. The moment you connect to google cloud service your data is encrypted in transit to a google cloud data center, where security is at its highest level. 

As you can see, containerization helps to deploy much faster and efficiently, thereby integrating security at every stage. The three stages of container security are Infrastructure security, software supply chain and runtime security.

Infrastructure security:

Infrastructure security ensures that the tools which they are given are securely built. These features are typically built into the Kubernetes itself. In addition to other features of Google Cloud, these capabilities are typically built into the container orchestrator, like Kubernetes. If you use Kubernetes Engine, this functionality is surfaced natively, in addition to other features of Google Cloud. Kubernetes engine users use network policy to manage pod to pod communications in your cluster. Kubernetes Engine uses container optimized OS by default and optimized for running containers. This is maintained by Google in open source.

Software supply chain:

The software supply chain is about knowing exactly what’s being deployed in your environment. The main fields to look into are controlling your applications and deployment. These features are usually built into your CI/CD pipeline and container registry, in this case, Google Container Registry. It provides both a Debian and Ubuntu base image, maintained by Google with regular patching and testing.

Google container registry also provides vulnerability scanning to scan your images and packages for any vulnerabilities. Latest patches are regularly rolled where containers can be rebuilt and redeployed.

Runtime security:

Container runtime security ensures that the security response team can detect and respond to threats to containers running in this environment. These capabilities are typically built into your security operations tooling. Google containers are monitored all the time. Kubernetes engine is integrated with stackdriver (cloud management service by Google) for easy log analysis. Another great feature is that it prevents one malicious container from affecting another. This feature also gives the user to monitor for attacks and view results in cloud SCC (security command centres).

Last but not least, the most important objective of Google is protecting data. Safeguarding the user’s online identities and unique credentials are very important. The organizations are protected by their employees’ identities and to further safeguard the company’s sensitive data Google also offers physical security key, which is unique for every employee and user as a result, the end-users need not think about any threats and vulnerabilities at all.
