What are security considerations for federated tables?

When using federated tables in MySQL, there are several security considerations to keep in mind. Federated tables allow you to access tables from a remote MySQL server, but they can open potential vulnerabilities if not configured properly. Here are some key security considerations:

  • Authentication: Ensure that robust authentication mechanisms are in place for the remote MySQL server to prevent unauthorized access.
  • Data Encryption: Use SSL/TLS to encrypt data transmission between the federated table and the remote server, protecting sensitive information from eavesdropping.
  • Access Controls: Implement strict access controls on both the local and remote databases, ensuring users have the least privileges necessary.
  • Query Limitations: Be aware that federated tables might allow execution of potentially harmful queries on the remote server, which could affect its performance.
  • Data Integrity: Regularly verify the integrity of the data in federated tables, as issues on the remote server can impact your local database.
