During the define requirements step of ZT planning, the organization will define its risk appetite, which is the amount and type of risk that it is willing to accept in pursuit of its objectives. Risk appetite reflects the organization's risk culture, tolerance, and strategy, and guides the development of the ZT policies and controls. Risk appetite should be aligned with the business priorities and needs, and communicated clearly to the stakeholders.

Business continuity and disaster recovery are the activities of the ZT implementation preparation phase that ensure the resiliency of the organization's operations in the event of disruption. Business continuity refers to the process of maintaining or restoring the essential functions of the organization during and after a crisis, such as a natural disaster, a cyberattack, or a pandemic. Disaster recovery refers to the process of recovering the IT systems, data, and infrastructure that support the business continuity. ZT implementation requires planning and testing the business continuity and disaster recovery strategies and procedures, as well as aligning them with the ZT policies and controls.

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.

Device validation helps establish a trusted connection based on certificate-based keys in a ZT deployment. Device validation is the process of verifying the identity and posture of the devices that request access to the protected resources. Device validation relies on the use of certificates, which are digital credentials that bind the device identity to a public key. Certificates are issued by a trusted authority and can be used to authenticate the device and encrypt the communication. Device validation helps to ensure that only healthy and compliant devices can access the resources, and that the connection is secure and confidential.

ZTA using enhanced identity governance is an approach to ZTA that strongly emphasizes proper governance of access privileges and entitlements for specific assets. This approach focuses on managing the identity lifecycle, enforcing granular and dynamic policies, and auditing and monitoring access activities. ZTA using enhanced identity governance helps to ensure that only authorized and verified entities can access the protected assets based on the principle of least privilege and the context of the request.

During the monitoring and analytics phase of ZT transaction flows, organizations should collect statistics and profile the behavior of transactions to support a continuous assessment of all transactions. A continuous assessment of all transactions means that the organization constantly evaluates the security posture, performance, and compliance of each transaction, and detects and responds to any anomalies, deviations, or threats. A continuous assessment of all transactions helps to maintain a high level of protection and resilience in the ZTA, and enables the organization to adjust and improve the policies and controls accordingly.

A critical product of the gap analysis process is the implementation's requirements, which are the specifications and criteria that define the desired outcomes, capabilities, and functionalities of the ZTA. The implementation's requirements are derived from the gap analysis, which identifies the current state, the target state, and the gaps between them. The implementation's requirements help to guide the design, development, testing, and deployment of the ZTA, as well as the evaluation of its effectiveness and alignment with the business objectives and needs.

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.
