What security mechanism is used in the OneFS API to encrypt communications?

The OneFS Platform API is a RESTful interface that relies on standard, secure web protocols for communication. It uses HTTPS (HTTP over Transport Layer Security/TLS) to encrypt the data in transit between an API client and the PowerScale cluster. This ensures the confidentiality and integrity of all API requests and responses, protecting sensitive information and configuration commands from eavesdropping or tampering.

A. SED (Self-Encrypting Drives) is a technology for data-at-rest encryption on the physical drives within the nodes, not for network communication.
B. RBAC (Role-Based Access Control) is an authorization framework that defines user permissions; it does not encrypt communication channels.
D. OpenSSH provides secure command-line (shell) access to the cluster; it is a separate protocol and not used for the web-based REST API.

2. Dell PowerScale OneFS 9.5.0.0 Security Configuration Guide, Page 10, Section: "Platform API (PAPI)". It specifies that PAPI access is secured using TLS and that only secure TLS protocols should be enabled.
