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.
