Study Notes

Client Session Management

Configure Policy Enforcement Points (PEPs) to respond exclusively to initial authentication requests.
Manage client sessions based on authorization decisions made by the Policy Decision Point (PDP).

Micro-Segmentation

Micro-segmentation enhances network security and simplifies management within Zero Trust Architecture (ZTA) solutions.
Identity-based policies provide effective segmentation instead of relying solely on address-based rules.
Resources are divided into distinct segments using network devices (switches, routers) or host-based micro-segmentation (software agents, endpoint firewalls).
Security gateways grant access based on identity attributes, requiring PEP management to prevent unauthorized access.
The primary goal is to define boundaries between resources within a network zone, allowing only authorized entities to access secured assets.

PEP Installation & Access Configuration

Post-PEP installation checks include implementing security measures like port knocking and single packet authorization (SPA) for obfuscation.
Assess device accessibility to both the PDP and network edge endpoints.
The PDP verifies user credentials and may invoke a Multi-Factor Authentication (MFA) process.
After verification, authorization data is sent to the PEP to facilitate secure communication.
Network configurations must permit only incoming and outgoing transmissions between the PEP and PDP.

Decision Transmission

Decision transmission is critical in ZTA, allowing the PDP to make access decisions based on user and contextual information.
Ensures users receive the minimum access necessary for their duties to protect sensitive data.
Secure data transmission between the PDP and PEPs requires:
- Configured network access for incoming/outgoing communications exclusively for PDP and PEPs.
- Established authentication between the two entities.
- Regular re-authentication challenges to maintain security.

Session Establishment and Termination

Establishing and terminating client sessions is vital to verify client identity, validate session data, and guard against man-in-the-middle attacks.
Session termination is crucial for protecting access for privileged users, such as company directors or medical professionals.
Centralized authentication, authorization, and monitoring are necessary, alongside application group segmentation.
High-level access policies are defined at the policy administrator level, evolving with ZTA stages from traditional to optimal practices.
Access organization should be based on specific access needs rather than job function or role to enhance security.

Networks & Environments Security

Implement Zero Trust Architecture (ZTA) best practices to defend networks from unauthorized visibility and access.
Key practices include identity-based policies, effective session management, micro-segmentation, installation of PDPs, and PEPs.
Redundant PEPs ensure failover and load balancing, maintaining service continuity in case of component failures.
ZTA structures security components by differentiating between control plane and data plane functions for improved security management.

Session Management

Proper configuration of Policy Enforcement Points (PEPs) requires responding solely to initial authentication requests.
Management of client sessions must align with authorizations provided by the Policy Decision Point (PDP).

Micro-Segmentation

Micro-segmentation enhances security and simplifies the management of network segments.
Identity-based policies, rather than traditional address-based rules, are preferred for securing network segments.
Resources are divided into distinct segments using network devices (switches, routers) or host-based methods (software agents, endpoint firewalls).
Access granted by security gateways is based on identity attributes, managed by PEPs to prevent unauthorized access.

PEP Installation & Access Configuration

Security checks post-PEP installation should include port knocking and single packet authorization for obfuscation.
Verify accessibility to both PDP and network endpoints.
A Multi-Factor Authentication (MFA) process verifies user credentials before sharing authorization data with PEPs.
Secure communication channels must be established exclusively between PEPs and PDPs, ensuring authentication and valid data transmission.

Decision Transmission

PDP makes access decisions based on user and context information, ensuring minimum access rights.
Secure data transmission between PDPs and PEPs requires limiting network access to inbound/outbound communications between these components.
Continuous re-authentication challenges help maintain a secure environment.

Session Establishment and Termination

Secure client session management involves identity verification and session data validation to prevent man-in-the-middle attacks.
Centralized authentication, authorization, and monitoring are critical for privileged users accessing the network.
Policies at the administrator level determine access based on job functions or roles, transitioning to need-based access in mature Zero Trust Architecture (ZTA).

Networks & Environments

ZTA emphasizes identity-centric policies, effective session management, micro-segmentation, and proper installation of PDPs and PEPs.
Redundant PEPs ensure failover and load balancing, maintaining service continuity.
Key objectives include successful phase completion, adequate funding for progress, and risk assessment before advancing.

ZT Policies

ZT policies align business missions with risk management requirements, documented within the ZT planning framework.
Near real-time communication between PDPs and PEPs enables the enforcement of access decisions based on established policies.
Access conditions depend on various parameters like user location and device approval during the onboarding process.

Transaction Configuration Management

A structured transaction inventory can be maintained, providing useful data for troubleshooting and documentation.
Tools may include configuration management systems or unified modeling language software for improved data management.

Testing

Post-implementation requires developing policies and agile testing scripts for consistent ZT testing processes.
Testing cycles must confirm that ZTA meets intended service levels while isolating problems originating from the new implementation or legacy systems.
