Identity management at the organizational level is a key aspect of cybersecurity because it ensures that only authorized users can access specific resources, systems, or data. By controlling and managing user identities, roles, and permissions, identity management helps enforce security policies, preventing unauthorized access and potential breaches. This is a fundamental practice in maintaining confidentiality, integrity, and availability within an organization.

A Web Application Firewall (WAF) is primarily used to filter and monitor HTTP requests to protect web applications from various types of attacks, including SQL injection and cross-site scripting (XSS). WAFs work by analyzing incoming traffic and blocking malicious requests based on predefined rules or patterns, thus preventing attackers from exploiting vulnerabilities in web applications.

CSP firewall is more focused on general network security, not specifically on application layer attacks like SQL injection or XSS. Virtual Appliance refers to a virtualized instance of a security appliance, but it is not specifically designedfor protecting against SQL injection and XSS attacks like a WAF. Intrusion Detection System (IDS) is used for detecting suspicious network activity and potential intrusions, but it is not focused on filtering web application traffic like a WAF.

In multi-tenant technologies, the fundamental security requirement issegmented and segregated customer environments. Multi-tenancy means that multiple customers (tenants) share the same physical or virtual infrastructure while maintaining logical separation to prevent data leakage and unauthorized access between tenants.

To ensure security and compliance in multi-tenant environments, providers implement:

Network segmentation (VLANs, Virtual Private Clouds)

Isolation mechanisms (such as virtual firewalls and access control lists)

Data isolation through encryption and access controls

Hypervisor-based isolation in virtualized environments

The goal is to create stronglogical isolationbetween tenants to mitigate risks likedata leakage, guest-hopping attacks, and unauthorized access.

Why Other Options Are Incorrect:

B. Limited resource allocation:While resource limits may help performance management, they do not inherently ensure security in multi-tenant settings.

C. Resource pooling:Though fundamental to cloud computing, it does not address the isolation needed for secure multi-tenancy.

D. Abstraction and automation:These are key elements in cloud computing but do not directly address multi-tenant security.

Encryption in object storage is used to secure stored data and protect it from unauthorized access, ensuring confidentiality. Reference: [Security Guidance v5, Domain 9 - Data Security]

Thehybrid clouddeployment model involves integrating a private cloud (or on-premises datacenter) with a public cloud, bound together by technology that enablesdata and application portability. This allows workloads to move seamlessly between environments, leveraging the benefits of both private and public clouds.

From theCCSK v5.0 Study Guide, Domain 1 (Cloud Computing Concepts and Architectures), Section 1.3:

“A hybrid cloud combines on-premises infrastructure (or a private cloud) with a public cloud, integrated through technology that allows data and application portability. This model enables organizations to maintain sensitive workloads on-premises while leveraging the scalability of public cloud services.”

Option A (Hybrid cloud) is the correct answer.

Option B (Public cloud) is incorrect because it involves only cloud provider resources, not a datacenter.

Option C (Multi-cloud) is incorrect because it refers to using multiple public cloud providers, not a datacenter.

Option D (Private cloud) is incorrect because it does not inherently include integration with a public cloud.
