Melissa George is a cloud security engineer in an IT company. Her organization has adopted cloud-based services. The integration of cloud services has become significantly complicated to be managed by her organization. Therefore, her organization requires a third-party to consult, mediate, and facilitate the selection of a solution. Which of the following NIST cloud deployment reference architecture actors manages cloud service usage, performance, and delivery, and maintains the relationship between the CSPs and cloud consumers?
Correct Answer: D
Cloud Service Integration: As cloud services become more complex, organizations like Melissa George's may require assistance in managing and integrating these services1. Third-Party Assistance: A third-party entity, known as a cloud broker, can provide the necessary consultation, mediation, and facilitation services to manage cloud service usage and performance1. Cloud Broker Role: The cloud broker manages the use, performance, and delivery of cloud services, and maintains the relationship between cloud service providers (CSPs) and cloud consumers1. NIST Reference Architecture: According to the NIST cloud deployment reference architecture, the cloud broker is an actor who helps consumers navigate the complexity of cloud services by offering management and orchestration between users and providers1. Other Actors: While cloud auditors, cloud carriers, and cloud providers play significant roles within the cloud ecosystem, they do not typically mediate between CSPs and consumers in the way that a cloud broker does1.

312-40 Exam Question 87
VenturiaCloud is a cloud service provider that offers robust and cost-effective cloud-based services to cloud consumers. The organization became a victim of a cybersecurity attack. An attacker performed a DDoS attack over the cloud that caused failure in the entire cloud environment. VenturiaCloud conducted a forensics investigation. Who among the following are the first line of defense against cloud security attacks with their primary role being responding against any type of security incident immediately?
Correct Answer: B
Incident Handlers are typically the first line of defense against cloud security attacks, with their primary role being to respond immediately to any type of security incident. In the context of a cybersecurity attack such as a DDoS (Distributed Denial of Service), incident handlers are responsible for the initial response, which includes identifying, managing, recording, and analyzing security threats or incidents in real-time. Here's how Incident Handlers function as the first line of defense: * Immediate Response: They are trained to respond quickly to security incidents to minimize impact and manage the situation. * Incident Analysis: Incident Handlers analyze the nature and scope of the incident, including the type of attack and its origin. * Mitigation Strategies: They implement strategies to mitigate the attack, such as rerouting traffic or isolating affected systems. * Communication: They communicate with relevant stakeholders, including IT professionals, management, and possibly law enforcement. * Forensics and Recovery: After an attack, they work on forensics to understand how the breach occurred and on recovery processes to restore services. References: * An ISACA journal article discussing the roles of various functions in information security, highlighting the first line of defense1. * An Australian Cyber Security Magazine article emphasizing the importance of identity and access management (IAM) as the first line of defense in securing the cloud2.
