PCCSE Exam Dumps : Prisma Certified Cloud Security Engineer

The external ID plays a crucial role when onboarding a new Amazon Web Services (AWS) account in Prisma Cloud. It serves as a UUID (Universally Unique Identifier) that establishes a trust relationship between the Prisma Cloud account and the AWS account. This trust relationship is essential for allowing Prisma Cloud to securely extract data and perform security monitoring and compliance checks within the AWS environment. The use of an external ID ensures that Prisma Cloud can access the necessary information from the AWS account without compromising the security of the AWS account's credentials, adhering to the principle of least privilege and enhancing the overall security posture.

Enabling the "block" option under compliance checks on a host in Prisma Cloud signifies a strict enforcement policy, where any container that violates specified compliance checks will be prevented from starting on that host. This preventive measure is crucial for maintaining a secure and compliant cloud environment, ensuring that only containers that meet the organization's compliance and security standards are allowed to run. This approach aligns with Prisma Cloud's proactive security posture management, where potential risks are mitigated before they can impact the cloud environment​​.
