VirtualCenter communications to the ESX Server are unencrypted.
Description
Discussion Text
User sessions with the ESX Server should be encrypted since transmitting data in plaintext may be viewed as it travels through the network. User sessions may be initiated from the VI client, Web Access, or through VirtualCenter. To encrypt session data, the sending component, such as a gateway or redirector, applies ciphers to alter the data before transmitting it. The receiving component uses a key to decrypt the data, returning it to its original form. To ensure the protection of the data transmitted to and from external network connections, ESX Server uses the 256-bit AES block encryption. ESX Server also uses 1024-bit RSA for key exchange. These encryption algorithms are the default for VI Client, VI Web Access, VirtualCenter sessions.
