Outbound notifications in Prisma Cloud refer to the integration with external systems or services for the purpose of alerting or incident management.

Option D: PagerDuty is an example of an outbound notification within Prisma Cloud. PagerDuty is a popular incident response and alerting service that teams use to manage, track, and respond to incidents in real-time. Prisma Cloud's integration with PagerDuty allows organizations to automatically forward alerts from Prisma Cloud to PagerDuty, enabling streamlined incident management and response workflows.

Prisma Cloud Integration Documentation: Provides instructions for integrating Prisma Cloud with various external services, including PagerDuty, to enhance alerting and incident management capabilities.

Incident Management Best Practices: Discusses strategies for effective incident management, highlighting the role of integrations with external alerting services like PagerDuty in improving response times and incident resolution.

To create a custom policy within a cloud security platform like Prisma Cloud, security teams have the flexibility to either add a new policy from scratch or clone an existing one to serve as a foundation for customization. Adding a new policy allows for the creation of a completely tailored rule set based on specific security requirements. Cloning an existing policy, on the other hand, provides a quick start by using the structure of an already established policy, which can then be modified to fit particular needs. This approach is beneficial for maintaining consistency with existing policies while addressing unique security scenarios. Disabling an out-of-the-box policy (option C) or editing the query in an out-of-the-box policy (option D) are actions that might be taken to customize policy enforcement but do not equate to the creation of a new custom policy.

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.

The Defender release image is built from the UBI8-minimal base image and on upgrade it is a full container image upgrade, which means that the old Defender container is replaced with a new container. Then, upgrade all other Prisma Cloud components, such as the Jenkins plugin.

The runtime audit message indicating 'DNS resolution of suspicious name wikipedia.com. type A' would appear as an audit because the DNS was not learned as part of the Container model or added to the DNS allow list (option A). In cloud security platforms like Prisma Cloud, runtime protection policies monitor the behavior of running containers and compare it against a learned model of expected behavior. If a container attempts to resolve a DNS name that was not observed during the learning phase or specifically allowed, it triggers an audit event to alert security teams of potentially malicious activity.

In the context of Kubernetes, an admission controller is a piece of code that intercepts requests to the Kubernetes API server before the persistence of the object, but after the request is authenticated and authorized. The admission controller lets you apply complex validation and policy controls to objects before they are created or updated.

The ValidatingWebhookConfiguration is a Kubernetes object that tells the API server to send an admission validation request to a service (the admission webhook) when a request to create, update, or delete a Kubernetes object matches the rules defined in the configuration. The webhook can then approve or deny the request based on custom logic.

The MutatingWebhookConfiguration is similar but is used to modify objects before they are created or updated, which is not the primary function of an admission controller acting in a protective or validating capacity.

DestinationRules are related to Istio service mesh and are not relevant to Kubernetes admission control.

PodSecurityPolicies (PSPs) are a type of admission controller in Kubernetes but they are predefined by Kubernetes and do not require a specific configuration object like ValidatingWebhookConfiguration. PSPs are also deprecated in recent versions of Kubernetes.

Therefore, the correct answer is C. ValidatingWebhookConfiguration, as it is the Kubernetes object used to configure admission webhooks for validating requests, which aligns with the role of Defender acting as an admission controller in Prisma Cloud.

Reference from the provided documents:

The documents uploaded do not contain specific details about Kubernetes objects or Prisma Cloud's integration with Kubernetes. However, this explanation aligns with general Kubernetes practices and Prisma Cloud's capabilities in securing Kubernetes environments.

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.

Both Console's API and web interfaces, served on port 8083 (HTTPS), require authentication over a different channel with different credentials (e.g. username and password, access key, and so on), none of which Defender holds. https://docs.paloaltonetworks.com/prisma/prisma-cloud/22-06/prisma-cloud-compute-edition-admin/technology_overviews/defender_architecture
