Similarly, to iDRAC network interfaces, iDRAC protocols, and modes of communication should be disabled if they are not needed as a security best practice. In addition to disabling all unused features and methods of communication, below are the security recommendations for interfaces to disable based on known security limitations inherent in the protocols.

1. IPMI over LAN disabled
2. Serial Over LAN disabled
3. Telnet Disabled (Telnet is removed from iDRAC firmware 4.40.00.00 and forward)
