Study Notes

User Credential Verification and MFA

User credentials are verified by the Policy Decision Point (PDP).
Multi-Factor Authentication (MFA) is initiated post-verification.
Authorization data is relayed to the Policy Enforcement Point (PEP).
Configure network access for secure incoming and outgoing communications between PDP and PEP.

Decision Transmission in Zero Trust Architecture (ZTA)

Decision transmission allows the PDP to make informed access decisions based on user and context data.
Ensures users receive minimal access necessary for job performance, enhancing data protection.
Secure data transmission requires network configurations that only accept communications from PDP and PEP.
Implement authentication between PDP and PEP and periodic re-authentication challenges.

Session Management and Security

Organizations must verify client identity during session establishment and termination.
Validation of session data is critical to prevent man-in-the-middle attacks.
Particular attention needed when privileged professionals log in from multiple devices.
Local device posture can be assessed using Network Access Control (NAC) or Unified Endpoint Management (UEM) solutions.

Regular Policy Evaluation and Update

Organizations need to regularly evaluate risk levels and transaction flows for alterations.
Adopt both macro- and micro-level approaches for access and authorization policies.
Updated policies should be re-applied to the policy engine in the PDP.

Transaction Flow Architecture Review

Maintain a transaction inventory to monitor behavior and detect abnormalities in data transactions.
Detailed mapping of transaction flows is necessary during the planning phase of ZTA.
Changes to transaction flows include adding ZT nodes and replacing legacy controls.
Focus on managing change at individual protective surfaces rather than the overall architecture.

Transaction Configuration Management Inventory

A sample table tracks transaction IDs, inputs, outputs, and service baselines for effective management.
Input and output data helps in troubleshooting and documenting fixes.
Transaction configuration can be documented using configuration management systems or UML tools.

Importance of Testing Post-Implementation

Develop policies and agile testing scripts to ensure consistent testing methodology across implementation stages.
Conduct testing in both non-production and production environments to validate ZT implementation.
Isolate problems to determine if they stem from the new implementation or previous system weaknesses.
