When multiple policies apply to the same request, they might conflict. One policy says allow, another says deny. Policy engines need a conflict resolution strategy to decide which rule wins.
Common Strategies
Deny Overrides
If any policy says deny, access is denied. Most secure, least flexible.
Allow Overrides
If any policy says allow, access is granted. More permissive, less secure.
Priority-Based
Policies have priorities. Highest priority wins. Most flexible, more complex.

Role vs Resource Policy Conflict
User has admin role (allow all) but resource is marked confidential (deny access)

Choosing a Strategy
Security-First: Deny Overrides
Choose this when security is paramount. Any restriction blocks access. Best for regulated industries, financial systems, healthcare.
Flexibility: Priority-Based
Choose this when you need fine-grained control. Define policy hierarchies. Best for complex organizations with many policy sources.
Most production systems use deny overrides as the default strategy. It is the most secure and easiest to reason about. Use priority-based resolution only when you have clear policy hierarchies and need flexibility. Document your resolution strategy clearly so all policy authors understand how conflicts are handled.
