When preparing to implement ZTA, some changes may be required.
Which of the following components should the organization
consider as part of their checklist to ensure a successful
implementation?
Governance: This refers to the establishment of a clear vision, strategy, and roadmap for ZTA, as well as the definition of roles, responsibilities, and authorities for ZTA stakeholders. Governance also involves the alignment of ZTA with the organization's mission, goals, and objectives, and the communication and collaboration among ZTA teams and other business units.
Compliance: This refers to the adherence to the relevant laws, regulations, standards, and policies that apply to the organization's ZTA. Compliance also involves the identification and mitigation of any legal or contractual risks or issues that may arise from ZTA implementation, such as data privacy, security, and sovereignty.
Risk management: This refers to the assessment and management of the risks associated with ZTA implementation, such as technical, operational, financial, or reputational risks. Risk management also involves the development and implementation of risk mitigation strategies, controls, and metrics, as well as the monitoring and reporting of risk status and performance.
Operations: This refers to the execution and maintenance of the ZTA processes, technologies, and services, as well as the integration and interoperability of ZTA with the existing IT infrastructure and systems. Operations also involve the optimization and improvement of ZTA efficiency and effectiveness, as well as the resolution of any operational issues or incidents.

To successfully implement ZT security, two crucial processes must
be planned and aligned with existing access procedures that the ZT
implementation might impact. What are these two processes?
Which of the following is a required concept of single packet
authorizations (SPAs)?
Which element of ZT focuses on the governance rules that define
the "who, what, when, how, and why" aspects of accessing target
resources?
Policy is the element of ZT that focuses on the governance rules that define the ''who, what, when, how, and why'' aspects of accessing target resources. Policy is the core component of a ZTA that determines the access decisions and controls for each request based on various attributes and factors, such as user identity, device posture, network location, resource sensitivity, and environmental context. Policy is also the element that enables the ZT principles of ''never trust, always verify'' and ''scrutinize explicitly'' by enforcing granular, dynamic, and data-driven rules for each access request.

ZT project implementation requires prioritization as part of the overall ZT project planning activities. One area to consider is prioritization based on risks, which means that the organization should identify and assess the potential threats, vulnerabilities, and impacts that could affect its assets, operations, and reputation, and prioritize the ZT initiatives that address the most critical and urgent risks. Prioritization based on risks helps to align the ZT project with the business objectives and needs, and optimize the use of resources and time.
