Study Notes

Identity Pillar

Identity encompasses authentication, authorization, and privileged access management (PAM).
Centralized directories and onboarding strategies support effective identity management.
Federation between enterprises facilitates identity sharing and validation.
Policy Decision Point (PDP) enforces identity rules and validations, including risk assessments and device posture checks.
Identity Providers (IdP) can be internal or external, such as SaaS applications.

PDP Identity Management

PDP administrators create policies and manage zero trust architecture (ZTA) at the control plane.
Each administrator must maintain at least two identity profiles:
- A primary profile for daily activities without elevated permissions.
- A secondary profile for elevated access to manage ZTA and SDP policies.

Applications & Workloads

The ZT implementation team identifies IPs, applications, and workloads for access needs.
Configuration at the PDP is geared towards onboarding with organized access requirements.
User credentials undergo verification, followed by multifactor authentication (MFA) before PDP shares authorization data with the Policy Enforcement Point (PEP).
Secure communications between PDP and PEP involve strict network access configurations.

Decision Transmission

Critical for ZTA, decision transmission ensures access is based on context and user information.
Users receive the least amount of access necessary for their duties, minimizing unauthorized data access.
Secure transmission between PDP and PEP includes:
- Exclusive network access for PDP and PEP communications.
- Authentication setup between PDP and PEP.
- Regular re-authentication challenges.

Session Establishment or Termination

Organizations must handle client sessions that verify identities and validate session data.
Essential for preventing man-in-the-middle attacks, especially for privileged roles accessing from various machines.

Network Signal Considerations

Six types of network signals support the security framework:
- Initial client authentication request from agent to PEP.
- Authentication request validation from PEP to PDP.
- Decision transmission from PDP to PEP.
- Client resource session establishment and termination.
- Micro-segmentation.
- PEP installation and access configuration.

Initial Client Authentication Request

Secure connections must enable mutual authentication between applications and servers.
Positioning the PEP at the network perimeter is vital while isolating PDP and resources.
Protocols should allow agents to send authentication requests to PEP, which forwards requests to PDP.
Encrypted channels are essential for secure authentication request transmission.

Authentication Request/Validation Request

AR/VR prevents identity spoofing and ensures only authorized requests are processed.
User agents securely share credentials with PEP for validation by PDP, reinforcing the authentication process.
