How can data security be enhanced in Splunk?

Enhancing data security in Splunk involves implementing role-based access controls and user authentication. This approach ensures that users only have access to the data and functionalities that are necessary for their specific roles within the organization. By defining roles with finely tuned permissions, the system can restrict access to sensitive information, thereby preventing unauthorized users from viewing, modifying, or deleting critical data.

User authentication further strengthens security by verifying the identities of those accessing the system, ensuring that only legitimate users are allowed entry. Together, these practices create a secure environment that upholds data integrity and confidentiality, especially in organizations dealing with sensitive or regulated data.

While other options may touch on aspects of security, they do not encompass the comprehensive strategies needed to create a secure data environment in Splunk. For instance, file encryption alone does not manage user access or authentication, limiting its effectiveness. Limiting the number of user accounts can be a management tactic but doesn't directly enhance security layers like role-based controls can. Moreover, avoiding data backups poses significant risk rather than enhancing security, as it leaves data vulnerable to loss or corruption.
