Study Notes
User Verification and MFA Process
- The Policy Decision Point (PDP) verifies user credentials and initiates additional Multi-Factor Authentication (MFA).
- Upon successful verification, authorization data is sent to the Policy Enforcement Point (PEP).
- Secure communication requires network access to be limited to transmissions between PDP and PEP only.
Decision Transmission in Zero Trust Architecture (ZTA)
- Decision transmission is vital for granting minimal access necessary for job performance, protecting data from unauthorized access.
- Implementations must include incoming and outgoing transmissions solely between PDP and PEP, authentication between them, and periodic re-authentication challenges.
Session Management
- Organizations need to establish and terminate sessions by verifying client identity, validating session data, and preventing man-in-the-middle attacks.
- Session termination is critical for privileged users logging on from various machines.
Network Signals for Secure Access
- Key network signal components include:
- Initial client authentication request from agent to PEP.
- Authentication request validation from PEP to PDP.
- Decision transmission from PDP to PEP.
- Session establishment and termination with resources.
- Micro-segmentation strategies.
- PEP installation and access configurations.
Initial Client Authentication Request
- Ensures mutual authentication for secure connections between applications and servers.
- Position PEP at the network perimeter while keeping PDP and resources on isolated segments.
- Utilize encrypted channels for secure transmission of authentication requests.
Authentication Request/Validation Request (AR/VR)
- AR/VR processes are crucial for preventing identity spoofing and ensuring only authorized requests are processed.
- User agents securely share credentials with PEP, which forwards them to PDP for validation.
Acronyms Related to ZTA
- API: Application Programming Interface
- MFA: Multi-Factor Authentication
- PDP: Policy Decision Point
- PEP: Policy Enforcement Point
- ZTA: Zero Trust Architecture
- NAC: Network Access Control
- SIEM: Security Information and Event Management
Importance of Secure Communication Channels
- Establishing secure, authenticated channels between PDP and PEP is essential for maintaining data integrity and security.
- Regular authentication and monitoring ensure ongoing compliance with access policies and safeguard against potential breaches.
