The given admission control policy is designed to evaluate pod creation requests in a Kubernetes environment, specifically targeting the creation of privileged pods, which can pose significant security risks.

• Option D: The policy will block the creation of a privileged pod is the correct answer when the effect of the policy is set to “block”. In this context, the policy's logic checks if a pod being created is set to run in privileged mode (a high-risk configuration that grants the pod extended system privileges). If such a configuration is detected, the policy triggers an action to block the pod's creation, thereby preventing the deployment of privileged pods that could undermine the security posture of the Kubernetes environment.

Configuring vulnerability policies within Prisma Cloud involves several options that cater to different aspects of vulnerability management and policy enforcement. Options A, C, and D are valid configurations for vulnerability policies:

A. Individual actions based on package type allow for tailored responses to vulnerabilities found in specific types of software packages, enabling more granular control over the remediation process.

C. Applying policies only when a vendor fix is available helps prioritize the remediation of vulnerabilities for which a patch or update has been released by the software vendor, ensuring efficient use of resources in addressing the most actionable security issues.

D. Setting individual grace periods for each severity level allows organizations to define different time frames for addressing vulnerabilities based on their severity, enabling a prioritized and risk-based approach to vulnerability management.

These configurations support a comprehensive vulnerability management strategy by allowing customization and prioritization based on the nature of the vulnerability, the availability of fixes, and the risk level associated with each vulnerability.

In Prisma Cloud, to notify the InfoSec team via email about misconfigured Security Groups, the appropriate tab to use is "Alert Rules." Alert rules in Prisma Cloud define the conditions under which alerts are generated and the notification channels, including email, where these alerts are sent. By configuring alert rules related to Security Group misconfigurations, the platform can automatically notify the team when such an event occurs, ensuring prompt awareness and response to potential security issues​​.
