User authorization in Low Level Design (LLD)
When implementing authorization in the Low-Level Design (LLD) phase of software development, you’re basically figuring out how the system decides who can do what. Here’s how you do it:
Below is the explanation of the steps mentioned above:
- Create an Authorization Module: Design a special part of the system that handles who gets permission to do certain things.
- Decide on Permission Structure: Figure out how permissions are structured—like who can access what—and how users or roles get these permissions.
- Choose Access Control Method: Decide whether you’re using Access Control Lists (ACLs) or Role-Based Access Control (RBAC) to manage access.
- Protect Resources: Plan how to safeguard important stuff (data, functions) based on who is allowed to access it.
- Context and Conditions: If needed, think about situations where access might change based on specific conditions, like the time of day or user location.
- Hierarchy and Roles: If applicable, design a system where higher-ups have control over permissions for those lower down in the hierarchy.
- Dynamic Changes: Plan for situations where permissions might change while the system is running.
- Keep Track of Actions: Design a way to keep a record of who accessed what, especially for security monitoring.
- Connect with Authentication: Make sure that the authorization part works closely with the authentication (login) system.
- Handle Errors: Decide what happens when someone tries to do something they’re not allowed to do—how does the system respond?
- Check Everything Works: Test the authorization system thoroughly to make sure it allows the right people to do the right things.
Difference between Authentication and Authorization in LLD | System Design
When building computer programs, especially when designing complex systems, it’s super important to understand two key things: authentication and authorization. Even though these words sound similar, they do different jobs to keep our systems safe.
