A cloud risk registry is primarily used to identify and manage risks associated with cloud services. It serves as a tool for documenting, tracking, and assessing potential risks to the organization that arise from using cloud services. This includes risks related to security, compliance, availability, and performance. The risk registry helps organizations prioritize and mitigate these risks effectively to ensure the security and resilience of their cloud infrastructure.

Establishing SLAs is related to cloud contract management but not the primary purpose of a risk registry. Monitoring real-time cloud performance is a performance monitoring task, not the focus of a risk registry. Managing cloudaccount credentials is an aspect of identity and access management, not related to risk registries.

Cloud adoption transforms how incident response (IR) is conducted. Unlike traditional IT environments, cloud environments involveshared responsibility,provider collaboration, andremote orchestration. This shift requires security teams to adjust response strategies, tools, and governance to effectively detect, analyze, and remediate incidents.

Cloud-specific tools (e.g., CSP logs, API calls, auto-scaling environments) must be incorporated into IR plans. Coordination with cloud service providers is often necessary to access logs, enforce controls, or conduct forensics.

This transformation is outlined inDomain 9: Incident Response, which stresses that effective IR in the cloud must be pre-planned and adapted to each provider and cloud model.

Immutable infrastructure maintains static configurations after deployment, ensuring consistency and preventing unauthorized changes. Reference: [Security Guidance v5, Domain 8 - Cloud Workload Security]

Integrating testing early helps identify security vulnerabilities and configuration issues before they reach production, reducing remediation costs and time. Reference: [Security Guidance v5, Domain 10 - Application Security]

TheManagement planein a network architecture is responsible for controlling all administrative actions, including configuration, management, monitoring, and maintenance of network devices and services. It provides the interface for administrators to interact with the network, perform system management tasks, and enforce policies.

The management plane typically includes functions such as:

Configuration management

Monitoring and logging

Administrative access control

Policy enforcement

In the context of cloud environments, the management plane also includes APIs and web-based consoles that allow administrators to manage virtual resources. Due to its critical role in controlling network and system settings, securing the management plane is of utmost importance to prevent unauthorized access and potential control over the entire network infrastructure.

Why Other Options Are Incorrect:

A. Forwarding plane:Responsible for the actual forwarding of data packets through the network based on predefined rules. It does not handle administrative functions.

C. Data plane:Responsible for data transmission and the forwarding of packets through the network but does not involve management tasks.

D. Application plane:This is not a commonly used term in network architecture, and it generally refers to application-specific functions rather than network administration.
