Step-by-step guide to set up a secure read-only PostgreSQL user
This guide will walk you through the process of creating a secure, read-only PostgreSQL user specifically for connecting to the application.
Creating a dedicated read-only user ensures:
Follow these steps to create your PostgreSQL read-only user:
First, connect to your PostgreSQL server as a superuser (usually ‘postgres’):
Create a new user with a secure password:
Replace ‘your_secure_password’ with a strong, unique password. Consider using a password manager to generate and store this securely.
Grant the user the ability to connect to the database:
Grant usage on the schema(s) you want the user to access:
Grant SELECT privileges on all tables in the schema:
For the application to function correctly, grant a few more privileges:
These permissions allow the user to:
To confirm that the user has been set up correctly:
Connect to PostgreSQL as the new read-only user:
Try to select data from a table:
Attempt to modify data (this should fail):
If you can select data but not modify it, your read-only user is set up correctly!
When setting up your connection in your application:
For additional security, consider using SSL connections and restricting the ‘readonly’ user to specific IP addresses if your application connects from known IP ranges.
If you encounter issues:
For further assistance, consult your database administrator or refer to the official PostgreSQL documentation.
By following this guide, you’ve created a secure, read-only PostgreSQL user that’s perfectly suited for connecting to your application. This setup ensures that your data remains protected while allowing your application to perform necessary read operations effectively.
