I think to prevent future breaches of confidential data in SQL databases, consider implementing the following measures: Strong Access Controls: Limit database access to only those who need it. Use role-based access control (RBAC) to enforce permissions. Data Encryption: Encrypt sensitive data both at rest and in transit to protect it from unauthorized access. Regular Monitoring and Auditing: Continuously monitor database activity and conduct regular audits to detect any suspicious behavior. Update and Patch: Keep your database software up to date with the latest security patches to mitigate vulnerabilities. Security Training: Provide ongoing training for team members on data security best practices to raise awareness and reduce error.

To prevent future data breaches, start by addressing the root cause. Implement clear policies on handling confidential data and ensure all team members are well-trained on them. Use database security measures like access controls, encryption, and activity monitoring to restrict and track access. Regular audits can help identify vulnerabilities early. Foster a culture of accountability and awareness so team members understand the importance of protecting data. Finally, have a clear incident response plan to act quickly if breaches occur, ensuring lessons learned are applied to prevent similar issues in the future.
