How does Splunk ensure data security?

Splunk ensures data security primarily through the use of role-based access control and encryption. Role-based access control (RBAC) allows administrators to define various roles within the organization, assigning different levels of access to data based on the responsibilities of each user. This means that sensitive data can be restricted to only those who need it for their job functions, minimizing the risk of unauthorized access.

Encryption further enhances security by protecting data both at rest and in transit. When data is encrypted, it becomes unreadable to anyone who does not have the appropriate decryption key, safeguarding it from potential breaches or unauthorized access during storage and transmission across networks. By implementing both of these strategies, Splunk provides a robust framework for protecting sensitive information from threats, ensuring that data remains confidential and secure within the organization.

Other options like limiting access to certain users might contribute to security, but it does not encompass the comprehensive approach of role-based access control and the added layer of encryption. Regular data backups are important for data recovery but do not inherently protect against unauthorized access. Compressing data, while beneficial for storage efficiency, does not relate to security measures in protecting data access or integrity.
