ACL system for user permissions in Redis - Mini Project: Build & Apply

ACL System for User Permissions in Redis

📖 Scenario: You are building a simple Access Control List (ACL) system using Redis to manage user permissions for a small web application. This system will store users and their allowed commands.

🎯 Goal: Create a Redis ACL setup where you add users with specific permissions, configure a default user, and verify the permissions setup.

📋 What You'll Learn

Create a user with a specific username and password

Assign command permissions to the user

Set a default user with limited permissions

Verify the ACL rules are correctly set

💡 Why This Matters

🌍 Real World

Managing user permissions securely in Redis is essential for protecting data and controlling access in real-world applications.

💼 Career

Understanding Redis ACLs is valuable for roles like backend developers, system administrators, and DevOps engineers who manage database security.

1

Create a user with username and password

Use the Redis ACL command ACL SETUSER to create a user called alice with password password123. The user should have no permissions.

Redis

# Your Redis command here to create user alice with password password123 and no permissions

Need a hint?

Use ACL SETUSER alice on >password123 nopass to create the user with no permissions.

2

Assign command permissions to the user

Add permissions for the user alice to allow the commands GET and SET using the ACL SETUSER command.

Redis

ACL SETUSER alice on >password123 +GET +SET
# Your code here to add permissions for alice

Need a hint?

Use +GET and +SET to grant command permissions.

3

Set a default user with limited permissions

Configure the default Redis user to be enabled with only the INFO command allowed and no password required.

Redis

ACL SETUSER default on +INFO nopass
# Your code here to configure default user

Need a hint?

Use ACL SETUSER default on +INFO nopass to configure the default user.

4

Verify the ACL rules are correctly set

Use the ACL LIST command to check that the users alice and default have the correct permissions set.

Redis

ACL LIST
# Your code here to verify ACL rules

Need a hint?

Use ACL LIST to display all users and their permissions.
