CCZT Online Practice Questions

Explanation:
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

Explanation:
(Configuring the security assertion markup language (SAML) service provider only to accept requests from the designated ZT gateway)
Configuring SAML to accept requests only from the designated ZT gateway ensures that all access requests are authenticated and authorized appropriately.

Explanation:
Data and asset classification should be based on the sensitivity of data, which is the degree to which the data requires protection from unauthorized access, modification, or disclosure. Data sensitivity is determined by the potential impact of data loss, theft, or corruption on the organization, its customers, and its partners. Data sensitivity can also be influenced by legal, regulatory, and contractual obligations.

Explanation:
The first step for an organization in defining priorities for ZT planning is to determine the current state of its network, security, and business environment. This involves conducting a comprehensive assessment of the existing IT infrastructure, systems, applications, data, and assets, as well as the threats, risks, and vulnerabilities that affect them. The current state analysis also involves identifying the gaps, challenges, and opportunities for improvement in the current security posture, as well as the business goals, objectives, and requirements for ZT implementation12. By determining the current state, the organization can establish a baseline for measuring the progress and impact of ZT, as well as prioritize the most critical and urgent areas for ZT adoption.

Explanation:
Network access control (NAC) typically operates at layer 2, the data link layer, of the open systems interconnection (OSI) model. The data link layer is responsible for transferring data between adjacent nodes on a network, such as switches and endpoints. NAC operates at this layer by inspecting and controlling the access of devices to the network based on their MAC addresses, device profiles, security posture, and compliance status.
