Description
The SDN controller is the backbone of the SDN infrastructure. If the server hosting the SDN controller is breached or if unauthorized changes are made to the device, the SDN controller may not have the appropriate resources to function properly or may even be disabled. A host intrusion detection system (HIDS) can monitor and report system configuration changes and prevent malicious or anomalous activity.

ℹ️ Check
Review all servers hosting an SDN controller and verify that an HIDS has been installed and enabled. If an HIDS has not been installed and enabled on all servers hosting an SDN controller, this is a finding.

✔️ Fix
Install and enable an HIDS on all servers hosting an SDN controller.
