# iLO 5 Gen10 security states

When you add a Gen10 node to SUM, communication between the iLO and host operating system occurs over the CHIF interface. Depending on the iLO security state, the communication operates in the following modes:

Normal mode (Production mode)

  In normal mode, communication is not encrypted.

Secure mode
  In secure mode (High security and FIPS), communication between the iLO and host operating system is encrypted, authorized, and authenticated.
  NOTE:

  Gen10 servers configured in the CNSA SuiteB state cannot be added to and managed by SUM 8.3.7.

Provide iLO administrator credentials for SUM to perform scouting, inventory, or deployment updates to an iLO in secure mode.

For more information about Gen10 server security modes, see the HPE Gen10 Security Reference Guide at https://www.hpe.com/info/sum-docs.
