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.
