PodSecurityPolicy is a critical Kubernetes security concept that helps control the security-sensitive aspects of pod configuration. One of its primary roles is to define the conditions under which a pod can be run in a cluster. This includes specifying what users can do within the pod and what resources the pod can access, which is essential for ensuring that sensitive files are not improperly accessed or read inside a container.

With PodSecurityPolicies, administrators can enforce rules that restrict the use of certain features or capabilities, such as the ability to use hostPath volumes that could expose sensitive information from the host filesystem to a pod. By enforcing policies that limit how containers can be configured and run, sensitive data can be better protected from unauthorized access within the container environment, thus enhancing the overall security posture of the Kubernetes deployment.

In contrast, other options like Network Policies focus on controlling the network traffic between pods, Resource Limits manage the compute resources a pod can use, and Service Mesh relates to service-to-service communication intricacies, none of which directly address the issue of sensitive files being exposed or read within a container.
