Troubleshooting & Diagnostic Fixes
1 SolutionsHow to Prevent IDOR and Broken Object Level Authorization
Symptom: Users can access other accounts’ private records simply by changing the ID in the API URL.
Solution: Enforce tenant-isolated database query filters (WHERE user_id = auth_id) on every request rather than trusting route parameters.
Architectural Comparisons (X vs Y)
1 DecisionsRBAC vs ABAC: Simplicity vs Granular Policy Matrix
Role-Based (RBAC)vsAttribute-Based (ABAC)
Architectural Verdict:RBAC is straightforward to implement for fixed role hierarchies; ABAC allows complex dynamic rules considering user, resource, action, and environment context.
Frequently Asked Questions (Q&A)
1 Direct AnswersQ:What is the fundamental difference between Authentication and Authorization?
Authentication verifies an identity (e.g., logging in with credentials), while Authorization determines the actions and resources that verified identity can access.
