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.
