ITGSS Certified DevOps Engineer Practice Test

What aspect should be evaluated in Kubernetes to ensure security during deployment?

1. The type of operating system used

2. Which programming language the application is written in

3. The confidentiality of secrets and volumes accessed

4. The age of the container images

The correct answer is: The confidentiality of secrets and volumes accessed

Evaluating the confidentiality of secrets and volumes accessed is critical in Kubernetes to ensure security during deployment. In Kubernetes, secrets are used to manage sensitive information such as passwords, OAuth tokens, and SSH keys. Protecting this data requires careful management and access control to prevent unauthorized access or leaks. Additionally, the configuration of volumes, which are used to store persistent data, should also be considered to ensure that any sensitive data stored is adequately secured. This involves implementing proper permissions and encryption where necessary, as well as ensuring that sensitive data is not exposed in logs or inadvertently shared with services that shouldn't have access. In contrast, while the type of operating system, the programming language, and the age of container images are important aspects in their own right, they do not directly address the security of sensitive information within the Kubernetes environment. The operating system might influence the security posture indirectly, and the programming language can affect vulnerabilities in the code, but the immediate concern in a Kubernetes context revolves around the handling of confidential information, making the evaluation of secrets and volumes paramount for maintaining security during deployments.
