Study Notes

User Behavior Monitoring

Malicious user actions are logged in a Security Information and Event Management (SIEM) platform.
Actions processed by analytics and forwarded to a Security Orchestration, Automation and Response (SOAR) platform for real-time policy decisions.

Compliance Improvement through Zero Trust Architecture (ZTA)

ZTA mandates frequent access policy reviews, ensuring alignment with evolving IT environments.
Policies are essential for security governance, interpreting organizational goals into actionable security rules.
Compliance with both external regulations and internal company policies is enhanced by strict access controls.
Continuous monitoring allows ongoing alignment of policy definitions with enforcement measures for better compliance.

Micro-segmentation and Access Control

Micro-segmentation enforces fine-grained authorization for each resource, assessing the user’s trustworthiness before granting access.
Access levels are dictated by policies based on user attributes, the requesting device, and user behavior.
Policy Enforcement Point (PEP) supports the principle of least privilege by enforcing Identity and Access Management (IAM) policies.
Multi-Factor Authentication (MFA) is commonly employed prior to establishing secure transport layer sessions (mTLS) for data transfers.

Identity Governance and Access Management

Enhanced identity governance establishes enterprise access policies based on user identity and attributes.
Access requirements include not only identity privileges but also device status and environmental factors.
Authentication processes involve user credentials validating the device, which then authenticates to the network and accesses resources through a policy engine.

Components of Zero Trust Architecture

Key logical components of ZTA as defined by NIST include Policy Decision Point (PDP) and Policy Enforcement Point (PEP).
PDP acts as the control plane, collecting and analyzing data to create access rules.
PEP functions as the data plane, enforcing rules and providing access to resources based on PDP inputs.
Data sources are crucial for maintaining up-to-date rules and aiding the policy engine in access decision-making.

Application in Real-World Scenarios

Examples include IEEE 802.1x network access control (NAC) using Lightweight Directory Access Protocol (LDAP) for authenticating corporate laptops to the network.
Resource access requests are verified through NAC, LDAP, and additional access management systems to ensure security.

Dynamic Policy Management

Contextual information is utilized to keep policies dynamically updated, optimizing security measures.
The effectiveness of ZTA components varies based on specific use cases and deployment models.
