CCSK Exam Dumps - Cloud Security Alliance Cloud Security Knowledge Questions and Answers

Acentralized bastion or transit networkimproves hybrid cloud security by:

Reducing cloud sprawlthrough a unified security control point.

Centralizing firewall, logging, and security monitoringfor betterthreat detection and response.

Enforcing consistent security policiesacross different cloud platforms (AWS, Azure, on-premises data centers).

Minimizing unauthorized lateral movementwithin hybrid cloud environments.

This concept is extensively covered in:

CCSK v5 - Security Guidance v4.0, Domain 7 (Infrastructure Security)

Cloud Controls Matrix (CCM) - Network Security and Monitoring​.

An Identity Provider (IdP) is responsible for authentication and authorization, particularly by managing user identities and their roles across various systems and services. In a cloud environment, the IdP facilitates the management of user, group, and role mappings that determine which users have access to which resources, including deployments across different cloud providers. The IdP acts as the central authority for managing identities and ensuring that users are granted appropriate access based on their roles and credentials.

Load balancing is a key resilience strategy in both traditional and cloud environments. It evenly distributes network or application traffic across multiple servers to ensure no single server becomes a point of failure or overloaded, thereby improving system availability, performance, and fault tolerance.

In cloud infrastructure, load balancers may work at various OSI layers (Layer 4 or Layer 7) and are often integrated into cloud platforms as managed services (e.g., AWS Elastic Load Balancer or Azure Load Balancer). They play a critical role in mitigating risks like traffic spikes, system failure, or regional outages.

This technique is described in Domain 7: Infrastructure Security of the CCSK guidance, which highlights tools like load balancing, redundant systems, and failover mechanisms to support cloud resilience and availability.

According to the CIS AWS (Center for Internet Security AWS) benchmarks, unauthorized API calls should be closely monitored because they indicate potential security threats or malicious activity within the AWS environment. Monitoring unauthorized API calls helps detect unauthorized access, misconfigurations, or attempts to exploit cloud resources. It's a key part of maintaining a secure AWS environment and helps ensure compliance with security best practices.

Regular file backups are important but not specifically a focus of the CIS AWS benchmarks. Data encryption at rest is a security best practice but monitoring unauthorized API calls directly addresses access control and security within the environment. Successful login attempts are important but monitoring failed login attempts (as opposed to successful ones) is generally a better practice for identifying suspicious activity.

A cloud workload refers to the application software or services that are deployed and run on cloud infrastructure or platform. It can include a variety of computing tasks such as processing data, running applications, or performing computations, depending on the type of workload. Cloud workloads are typically virtualized and managed within cloud environments, utilizing resources like compute, storage, and networking provided by the cloud infrastructure or platform.

A network of servers connected to execute processes refers more to the underlying infrastructure, not the workload itself. A collection of physical hardware used to run applications describes the infrastructure, not the workload. A single software application hosted on the cloud is a partial description but doesn’t capture the broader concept of workloads, which could include multiple services or applications.

A key component of governance in cybersecurity is defining roles and responsibilities. Governance ensures that the right people within an organization are assigned specific duties related to security and that they are held accountable for those responsibilities. This helps establish clear lines of authority and accountability, ensuring that everyone knows what they are responsible for in terms of security practices, policies, and procedures.

While standardizing technical specifications, defining tools and technologies, and enforcing penetration testing are important elements of a cybersecurity strategy, defining roles and responsibilities is essential for overall governance to ensure that security practices are consistently followed.
