Quota-Based Access Control

A method of controlling access to resources based on predefined usage limits or quotas.

Understanding:

Quota-Based Access Control (QBAC) is an access management model that limits user or system access based on predefined quotas. Instead of binary access permissions, QBAC restricts access based on usage limits, time windows, or transaction quotas.

Common Applications and Use Cases:

Cloud Resource Management – Limits API calls, compute usage, or data transfers per user.
Enterprise Security Policies – Enforces time-based or request-based access restrictions.
Fraud Prevention – Detects abnormal usage patterns exceeding preset thresholds.

Best Practices and Security Considerations:

Define Clear Quotas & Thresholds – Prevent resource abuse while ensuring legitimate access.
Monitor Usage in Real-Time – Use SIEM tools to track quota violations and generate alerts.
Implement Adaptive Quotas – Adjust access limits based on user behavior and risk assessment.
