Cloud Security Alliance CCZT Exam Dumps - Valid Questions Answers

A comprehensive catalogue of all transactions, dependencies, and services with associated IDs is a potential outcome of an effective ZT implementation because it helps to map the data flows and interactions among the assets and entities in the ZTA. This catalogue enables the ZTA to enforce granular and dynamic policies based on the context and attributes of the transactions, dependencies, and services. It also facilitates the monitoring and auditing of the ZTA activities and performance.

ABAC is an access control method that uses attributes of the requester, the resource, the environment, and the action to evaluate and enforce policies. ABAC allows for fine-grained and dynamic access control based on the context of the request, rather than predefined roles or privileges. ABAC is suitable for SaaS and PaaS, where the features within a service may vary depending on the customer’s needs, preferences, and subscription level. ABAC can help implement ZT by enforcing the principle of least privilege and verifying every request based on multiple factors.

According to NIST, the key mechanisms for defining, managing, and enforcing policies in a ZTA are the policy decision point (PDP), the policy enforcement point (PEP), and the policy information point (PIP). The PDP is the component that evaluates the policies and the contextual data collected from various sources and generates an access decision. The PEP is the component that enforces the access decision on the resource. The PIP is the component that provides the contextual data to the PDP, such as the user identity, the device posture, the network location, the resource attributes, and the environmental factors.
