“When integrating third-party APIs with FaaS, each connection potentially increases the attack surface by exposing additional authentication, authorization, and data access points.”

The multi-tenant nature of cloud computing refers to the model where multiple cloud customers share a common pool of resources (such as computing power, storage, etc.), but each customer's data and applications are segregated and isolated from the others to ensure privacy, security, and independent performance. This approach allows cloud providers to efficiently use resources while ensuring that each tenant's environment is protected and operates independently.

During the Detection and Analysis phase of incident response, the primary objective is to validate alerts to determine whether they represent a genuine security incident, and to estimate the scope of the incident to understand the potential impact on the organization. This phase involves analyzing evidence, confirming the nature of the incident, and gathering the necessary information to move forward with containment and remediation.

Developing and updating incident response policies is important but occurs more during the preparation phase, not during the detection and analysis of an active incident. Performing detailed forensic investigations typically takes place during later phases, such as Containment, Eradication, & Recovery or Post-Incident Analysis. Implementing network segmentation and isolation may be part of the Containment phase but is not the primary focus during the Detection and Analysis phase.

Consulting with stakeholders is crucial for ensuring that the cloud security strategy aligns with the overall business objectives and needs. Stakeholders — such as business leaders, IT teams, legal, and compliance officers — bring unique perspectives on what the cloud strategy needs to accomplish, from security to compliance, scalability, and performance. By involving stakeholders, organizations can ensure that the security strategy supports business goals, addresses various concerns, and is comprehensive.

Simplifying the cloud platform selection process is a potential benefit but not the primary reason for consulting stakeholders. Selecting the right cloud platform is part of the broader strategy. Reducing the overall cost of cloud services is not necessarily the outcome of involving stakeholders, although cost considerations may be part of the discussion. Ensuring compliance with technical standards only is too narrow; stakeholders help ensure compliance with both technical and business requirements.

Correct Option: A. Failure to update access controls after employee role changes

This falls under one of the most common risk factors related to cloud misconfiguration and poor change management. Misconfiguration errors often stem from insufficient change control, especially in dynamic environments like the cloud. According to CSA’s Security Guidance v4.0, poor governance of identity and access management (IAM) changes — such as not updating access privileges when user roles change — introduces serious security risks.

"Cloud computing is dynamic by nature. This places more importance on automation and proper governance, especially for identity and access control. Failure to remove or update access permissions after personnel changes leads to orphaned or over-permissioned accounts, which are prime targets for attackers."

Also highlighted in ENISA’s Cloud Risk Assessment:

"Loss of governance includes failing to maintain proper control over access privileges and role assignments. Poor change management and inadequate configuration reviews can leave systems open to unauthorized access."

Why the Other Options Are Incorrect:

B. Lack of sensitive data encryption: While encryption is critical, it is not directly tied to change control or misconfiguration, but rather falls under Data Security and Encryption domain.

C. Lack of 3rd party service provider specialized in patch management procedures: This refers more to vendor management and Security-as-a-Service, not internal change control or misconfigurations.

D. Excessive SBOM focus: Software Bill of Materials (SBOM) is important for supply chain transparency, but excessive focus on it isn’t a typical misconfiguration or change control risk.

TheShared Responsibility Modelin cloud computing establishes that:

Cloud providersare responsible for securing the underlyinginfrastructure, networking, and hardware.

Customers (organizations)are responsible for securingdata, identity and access management (IAM), encryption, and complianceobligations.

Data ownershipremainswith the customer, even though visibility into cloud infrastructure may belimited.

The major security challenge in cloud computing is thatorganizations lack full control over cloud infrastructurebut must still ensure that security policies align withregulatory requirements (e.g., GDPR, HIPAA, PCI DSS).

This principle is outlined in:
