When you log in to the NIOS appliance, your computer makes an HTTPS (Hypertext Transfer Protocol over Secure Sockets Layer protocol) connection to the NIOS appliance. HTTPS is the secure version of HTTP, the client-server protocol used to send and receive communications throughout the Web. HTTPS uses SSL (Secure Sockets Layer) and/or TLS (Transport Layer Security) protocols to secure the connection between a client and server. SSL/TLS provides server authentication and encryption. The NIOS appliance supports TLS versions 1.0, 1.1, and 1.2. TLS provides cipher suites that are used to negotiate the security settings for the secure connection. Infoblox has provided a few CLI commands so you can enable and disable specific cipher suites. For detailed information about these CLI commands, refer to see Using the Infoblox NIOS CLI Guide.
Note that enabling or disabling the TLS ciphers will enable or disable the equivalent SSHd cipher. The following table lists the TLS suite name and the corresponding OpenSSL suite name, SSHd cipher name, and SSHd MAC name:
