Authorization in software systems is like getting a specific wristband at a festival that allows you access to certain areas. It's about granting or denying permissions to do something after your identity is verified.

• After Authentication: Authorization always comes after authentication. First, the system recognizes you (like the club knows who you are), and then it decides what you are allowed to do (like what areas of the club you can enter).

• Roles and Permissions:

  • Roles: These are like different types of wristbands or badges. For example, an 'Admin' might have access to everything, while a 'User' has limited access.
  • Permissions: Specific actions you're allowed to perform, like viewing, editing, or deleting information. If you're at a festival, it's like being allowed to enter backstage areas, VIP sections, or just the general area.

• Importance:

  • Security: It prevents users from accessing data or actions that they shouldn't. Like keeping regular festival-goers out of VIP areas.
  • Data Integrity: Helps ensure that data isn't wrongly modified or deleted.
  • Compliance: Many industries have regulations about who can access or modify certain data.

• Examples:

  • File System Permissions: Like on your computer, where some files are only accessible by the administrator.
  • Database Roles: In a company's database, different employees have different levels of access based on their job.
  • Web Application Privileges: On a website, a regular user might only view content, while an editor can create and edit content, and an administrator can access user data and site settings.

Authorization is about having the right level of access to resources in a software system. It's crucial for maintaining order and security, much like different access levels are important in a well-organized event or facility.
