Scenario: A security breach occurs in your Data Lake, resulting in unauthorized access to sensitive data. How would you respond to this incident and what measures would you implement to prevent similar incidents in the future?

In response to a security breach in a Data Lake, an organization should enact its incident response plan, implement data encryption to protect sensitive data, enforce access control policies to limit unauthorized access, and conduct security auditing to identify vulnerabilities. Preventative measures may include regular data backups, disaster recovery plans, and data masking techniques to obfuscate sensitive information.
