Cloud computing uses abstraction and automation to pool and distribute resources efficiently among multiple tenants. This allows dynamic allocation based on demand. Reference: [CCSK v5 Curriculum, Domain 1 - Cloud Computing Models]

The principle of Segregation of Duties (SoD) focuses on implementing multiple security layers by dividing responsibilities among different individuals or systems to ensure that no single entity has enough control to misuse or compromise access. This principle helps to prevent fraud, error, and misuse by ensuring that critical tasks are divided and that sensitive actions require multiple people or processes to perform, adding an extra layer of security.

Continuous Monitoring refers to the ongoing observation of activities to detect unusual behavior, but it is not directly about diluting access power. Federation involves linking multiple identity management systems together to allow access across different domains but does not specifically address limiting access power through multiple security layers. Principle of Least Privilege ensures that users have only the minimum necessary access to perform their tasks, but it does not directly involve dividing duties or responsibilities.

The principle of least privilege limits access to only necessary permissions, reducing the risk of misuse and exposure of sensitive data. Reference: [CCSK v5 Curriculum, Domain 5 - IAM]

InInfrastructure as a Service (IaaS), the customer has themost control and security responsibilitybecause:

The provider only secures physical infrastructure (data centers, networking, hardware).

Customers must configure and manage firewalls, network security, operating system patches, and IAM.

Data security, encryption, and application security are entirely the customer's responsibility.

In contrast:

PaaS (Platform as a Service)places some security responsibility on the provider (e.g., runtime environments, managed databases).

SaaS (Software as a Service)places most security responsibility on the provider, with customers mainly managingidentity and access controls.

This is extensively discussed in:

CCSK v5 - Security Guidance v4.0, Domain 1 (Cloud Computing Concepts and Architectures)

Cloud Controls Matrix (CCM) - Infrastructure and Application Security Controls​.

The primary benefit of implementing micro-segmentation within a Zero Trust Architecture is that it enhances security by isolating workloads from each other. Micro-segmentation involves dividing the network into smaller, isolated segments, so that even if an attacker gains access to one part of the network, they cannot easily move laterally to other parts. This is crucial in a Zero Trust model, which assumes that threats may exist both inside and outside the network, and security is enforced at a granular level for each workload.

Simplifying network design is not a benefit of micro-segmentation; in fact, it can add complexity due to the increased number of network segments. Increased network performance is not a primary outcome of micro-segmentation, which may introduce overhead. Reducing the need for encryption is incorrect because micro-segmentation doesn't eliminate the need for encryption; it works alongside encryption to provide better security.
