Doris User Authentication and Authorization (Role and Permission Management)

Introduction

User authentication and authorization are critical aspects of security management, focusing on how to ensure systems effectively identify and verify users and grant appropriate access permissions.

Why?

User authentication and authorization are crucial for ensuring system security. Incorrect access or authorization could lead to severe consequences, such as data leaks or system disruption. Therefore, user authentication and authorization must be carefully designed and implemented.

System Role Management

System roles are defined based on different types of system functions, operations, or permissions. They are typically categorized into the following roles:

1. super admin (Super Administrator)

Possesses the highest level of authority and can perform any operation on the system, including user authentication and authorization.

2. administrator (Administrator)

Responsible for managing and maintaining the system but does not possess the authority of a super administrator.

3. user (Regular User)

Can only access functions provided by the system and typically has no direct control over the system.

System Permission Management

Permissions are based on system roles and determine what operations a user can perform within the system. They are generally categorized into the following permissions:

1. read (Read)

Allows users to view information or data within the system.

2. write (Write)

Allows users to modify or add information or data within the system.

3. delete (Delete)

Allows users to remove information or data within the system.

4. execute (Execute)

Allows users to trigger system operations or functions, such as executing commands.

Implementation Methods

The following methods are commonly used to implement system role and permission management:

1. Manual Assignment

Manually add users to the system and assign them the corresponding roles and permissions.

2. Automatic Assignment

Automatically assign roles and permissions to users based on their behavior, operations, or attributes.

3. Configuration Files

Use configuration files to store definitions of system roles and permissions, facilitating management and maintenance.

Best Practices

The following are some best practices when implementing system role and permission management:

1. Multi-Factor Authentication

Enhance security by using multiple authentication methods (e.g., password, BIOMETRIC, etc.).

2. Random Assignment

After assigning roles and permissions, randomly assign users to roles to prevent attacks that favor the system.

3. Regular Updates

Regularly update system role and permission definitions to ensure system security and effectiveness.
