Database Security Tips
Simple rules to keep your database safe.
Tip 1: Use Strong Passwords
Bad: password123 Good: aB9$mK2pQz#7
Tip 2: Give Minimum Permissions
Only give permissions people actually need.
-- Good: Read-only for viewers
GRANT SELECT ON products TO viewer;
-- Bad: Full access for everyone
GRANT ALL ON products TO everyone;Tip 3: Never Store Passwords in Plain Text
Wrong: password = "mypassword123" Correct: Use password hashing
Tip 4: Use Transactions for Important Operations
Always use BEGIN/COMMIT for money transfers, orders, etc.
Tip 5: Backup Your Database Regularly
Like backing up photos - if something goes wrong, you can restore.
