CCZT Dumps with Practice Exam Questions Answers

The ZT tenet of assume breach is based on the notion that malicious actors reside inside and outside the network, and that any user, device, or service can be compromised at any time. Therefore, ZT requires continuous verification and validation of all entities and transactions, and does not rely on implicit trust or perimeter-based defenses

Micro-segmentation is a vital ZTA component that enhances network security and simplifies management by creating boundaries between resources in the same network zone. Micro-segmentation divides the network into smaller segments or zones based on the attributes and context of the resources, such as data sensitivity, application functionality, user roles, etc. Micro-segmentation helps to isolate and protect the resources from unauthorized access and lateral movement of attackers within the same network zone.

A common activity in the scope, priority, and business case steps of ZT planning is to determine the organization’s current state. This involves assessing the existing security posture, architecture, policies, processes, and capabilities of the organization, as well as identifying the key stakeholders, business drivers, and goals for the ZT initiative. Determining the current state helps to establish a baseline, identify gaps and risks, and define the scope and priority of the ZT transformation.

In a ZTA, policies should be created in the control plane, which is the logical component that defines and manages the policies for accessing resources. The control plane consists of policy entities, such as policy administrators, policy engines, and policy decision points, that are responsible for crafting, maintaining, evaluating, and enforcing the policies1. The control plane interacts with the data plane, which is the logical component that handles the data transmission and processing, and the network, which is the physical or virtual component that provides the connectivity and transport for the data plane1. The endpoint is the device or system that requests or provides access to a resource1.

In a Zero Trust Architecture, the Policy Decision Point (PDP) is the primary entity responsible for crafting and maintaining policies, especially those that enforce the principle of least privilege for network access. The PDP evaluates all relevant information about an access request—including the identity of the requester, the context of the request, and the requested resource—and makes a decision on whether to grant or deny access based on predefined policies. This process ensures that access rights are strictly aligned with the necessity of the role and the minimum access required to perform a function, thereby adhering to the principle of least privilege​​.
