PCCSE Leak Questions

In the context of calculating net effective permissions for a resource in AWS, IPTables firewall rule is not used. Net effective permissions in AWS are determined by evaluating various AWS-specific mechanisms such as IAM policies, permission boundaries, and service control policies (SCPs). IAM policies define what actions are allowed or denied for various AWS resources. Permission boundaries provide a way to delegate administration for IAM entities, setting the maximum permissions that an IAM entity can have. SCPs are part of AWS Organizations and allow for central control over the maximum available permissions for all accounts within an organization. IPTables, on the other hand, is a Linux-based application for setting up firewall rules on individual hosts and is not directly related to AWS resource permissions. Therefore, IPTables firewall rules are not considered when calculating net effective permissions in AWS, making option C the correct answer.

In Prisma Cloud Enterprise Edition, Palo Alto Networks hosts and runs the Console component. The Console serves as the central management interface for Prisma Cloud, allowing customers to configure policies, view alerts, and manage their cloud security posture without the need to host this component themselves.

The question focuses on valid host compliance policies within a cloud environment. Among the given options, the most relevant to host compliance is ensuring compliant Docker daemon configuration. Docker daemon configurations are critical for securing the host environment where containers are run. A compliant Docker daemon configuration involves setting security-related options to ensure the Docker engine operates securely. This can include configurations related to TLS for secure communication, logging levels, authorization plugins, and user namespace remapping for isolation.

Ensuring functions are not overly permissive (Option A) and ensuring images are created with a non-root user (Option C) are more directly related to the security best practices for serverless functions and container images, respectively, rather than host-specific compliance checks. Ensuring host devices are not directly exposed to containers (Option B) is also important for security, but it falls under the broader category of container runtime security rather than host-specific compliance.

Thus, the most valid host compliance policy from the given options is to ensure a compliant Docker daemon configuration, as it directly impacts the security posture of the host environment in a containerized infrastructure. This aligns with best practices for securing Docker environments and is a common recommendation in container security guidelines, including those from Docker and cybersecurity frameworks.

In AWS, the net effective permissions are calculated based on various policy types and identities. The correct choices are:

• A. AWS service control policies (SCPs): SCPs are used in AWS Organizations to manage permissions for all accounts within the organization, affecting the net effective permissions.
• B. AWS IAM group: IAM groups define a set of permissions for a collection of users, influencing their effective permissions.
• C. AWS IAM role: IAM roles provide temporary security credentials to assume a set of permissions, impacting the net effective permissions. Option D (AWS IAM User) and E (AWS IAM tag policy) also play roles in defining permissions, but A, B, and C are the primary types used in calculating net effective permissions, making them the correct choices.
