Access control and permission management are core components of any Identity and Access Management (IAM) system and IT infrastructure. They define roles across your organization — from regular users to administrators and financial auditors — and govern who can access internal and external services.
Core principles of permission management
Principle of least privilege
Grant each user only the minimum permissions required to do their job. Applying this principle helps you:
Prevent permission abuse before it happens
Maintain security and minimize the impact on productivity
Reduce user confusion from permissions that don't apply to their role
Permission change tracking
Track permission changes in real time. Any additions or removals must take effect immediately in a user's permission list. Real-time tracking keeps permissions synchronized with user levels and statuses, and prevents permission mismatches when users change teams or leave the organization.
Fine-grained permission assignment
Assign permissions based on user duties and actual needs — not broad roles. For example:
Regular users can access specific applications (such as Application A) but not others (such as miniapp B).
Phone support agents can view user accounts and make limited edits — changing phone numbers, resetting passwords, or unlocking accounts — but cannot create or delete accounts.
Regional administrators can manage accounts in a specific region (such as North China) with no access to accounts in other regions.
Choose an authorization model
Alibaba Cloud IDaaS offers various authorization models, such as role-based, group-based, and attribute-based authorization. Select the one that fits your organization's structure and access patterns.
| Model | Best for | Example |
|---|---|---|
| Role-based | Organizations with clearly defined job functions | Assign an "Agent" role with read and limited edit permissions to all phone support staff |
| Group-based | Teams or departments that share the same access needs | Grant the North China admin group access to regional accounts |
| Attribute-based | Dynamic or context-sensitive access requirements | Allow access only during business hours, or only from specific locations |
These models can be combined into an authorization matrix, giving you fine-grained control over complex permission scenarios and multiple authorization flows.
Compliance and performance
Alibaba Cloud IDaaS has passed authoritative assessments, such as Level 3 Protection Certification and the ISO series, ensuring legal compliance for your information system development.
IDaaS handles demanding workloads — including batch authorization and high-frequency authentication — without compromising usability or flexibility.
