What factors influence the choice of authorization design in SaaS?

“Key factors influencing SaaS authorization design include system complexity, scalability requirements, and granularity of permissions needed. Simple systems may suit ACL; RBAC works well for role-based structures, while ABAC is ideal for context-sensitive, detailed permissions. Considerations like maintenance effort, business growth projections, and security requirements also play crucial roles in selecting an effective and sustainable authorization model.”
