10 iDRAC Service Module – OS based capabilities for Out-of-band management with iDRAC9 | 469
executable links and loads. This ensures only an authentic iSM executable can get installed, adding to
security.
3.3.3 TLS layer encryption between iSM and iDRAC
To further enhance the security, the data communication between iSM and iDRAC happens through TLS
protected USBNIC INET sockets. This ensures protection of all the data that transports from iDRAC to iSM
over USBNIC.
iSM and iDRAC use self-signed certificates to control authentication. The self-signed certificates have 10
years of validity. Fresh self-signed certificates are generated while installing iSM every time. Reinstall or
upgrade iSM if the certificates expire.
