Implement NIST Zero Trust Architecture (ZTA) Step by Step

Explore variations of zero trust architecture for enterprise workflows, and how a comprehensive solution integrates enhanced identity, governance driven, logical micro-segmentation, and network based segmentation.

Explore how enhanced identity governance builds zero trust policies from user identity and attributes, with MFA, device posture, and network context shaping access decisions.

Explore how zero trust architecture uses microsegmentation to place resources on unique segments protected by gateway policy enforcement points, with gateway and host-based controls and a robust identity governance program.

Apply a zero trust architecture using software defined perimeters and overlay networks, guided by a policy administrator and policy engines to enforce PEPs and TLS access.

Explore the flexible, logical nature of zero trust architecture components, where a single asset can fulfill multiple roles and deployment models can be mixed and matched to fit enterprise needs.

Describe a device agent gateway based zero trust deployment where a local device agent and gateway form dual policy enforcement, with a policy administrator and engine authorizing encrypted TLS access.

Deploy enclave-based zero trust by placing gateways at resource enclave boundaries to protect legacy systems and resources behind a private cloud, with device agents and policy engines coordinating secure access.

Learn how resource portal-based deployment in zero trust uses a policy enforcement point gateway to manage access to private clouds and legacy apps without client agents, enabling BYOD.

Implement device application sandboxing by running vetted apps in isolated environments (VMs and containers) to protect from compromised hosts, with access controlled by a policy enforcement point and TLS.

Explore how the trust algorithm powers the policy engine to evaluate inputs from subjects, assets, and threat intel, granting access only after MFA, country IP checks, and TLS session setup.

Explore variations of trust algorithms in a zero trust architecture, comparing binary decision and weighted score approaches with criteria-based, score-based, and contextual methods, thresholds, weights, and history-aware evaluations for access.

Explore how zero trust networks separate control and data planes, using the policy administrator, policy enforcement point, and policy engine to authenticate, authorize, and establish secure communication paths.

Explore deployment scenarios for zero trust architecture, including multi-cloud, remote workers, and hybrid perimeters, with policy enforcement points, a cloud-hosted policy engine and policy administrator enabling secure, authenticated access.

Assess threats in zero trust architecture, including policy engine and policy administrator misconfigurations. Mitigate with DDoS protection, MFA, contextual trust, encrypted traffic visibility, and robust monitoring.

Plan a gradual migration to a zero trust architecture by identifying assets, subjects, processes, and dependencies to build a baseline and enable incremental, hybrid security with perimeter controls.

Survey assets, data flows, workflows, and subjects to inform the policy engine in zero trust, address shadow IT, and map steps to the RMF for risk reduction.

Identify actors in zero-trust architecture via the policy engine, detailing human users and non-person entities, including service accounts, while applying stricter scrutiny for developers and admins with verification and audits.

Identify and manage enterprise assets and monitor non-enterprise devices to support policy decisions, with observable asset state from configuration management of physical, virtual assets including containers, and network locations.

Identify and rank business processes, data flows, and roles, evaluate access risks, and start with low-risk, cloud-based or remote-work processes to implement zero trust architecture with policy enforcement points.

Identify a zero trust architecture (zta) candidate, map upstream and downstream resources, and define policy criteria and weights using the nist risk management framework.

Identify candidate solutions for zero trust architecture by evaluating deployment models, client asset requirements, cloud versus on-prem resources, and logging for policy-driven access decisions.

Implement the zero trust deployment in reporting only mode using Palo Alto Networks for policy engine and Cisco DNA Center for policy administration, while monitoring with Splunk and refining policies.

expand the zero trust architecture by refining purchasing workflows, maintaining a steady operational phase with continuous monitoring and logging, and guiding the next deployment phase through stakeholder feedback and planning.

Implement a step-by-step approach to NIST zero trust architecture, evaluating candidate solutions, deploying ZTA, and refining policies with monitoring and logging tools across business processes.
