7. Securing unstructured data: Traditional relational databases are well-equipped to handle structured data but struggle with unstructured data such as images, videos, social media posts, etc. Securing this type of data poses unique challenges that need to be addressed as its volume grows.

8. Data backups and disaster recovery: With larger volumes of data, it becomes increasingly important to have a robust backup strategy in place. Organizations must also consider disaster recovery plans in case of system failures, natural disasters, or other events that could compromise the security of their databases.

9. Employee training: As databases become more complex, it will be crucial for organizations to train their employees on data security best practices. This includes understanding how to properly handle and protect sensitive data, as well as identifying and responding to potential security threats.

10. Compliance with industry regulations: Different industries have specific regulations and standards for data security that must be adhered to. As databases grow larger and more complex, it may become more challenging for organizations to comply with these regulations.
