The SDN controller must be configured to encrypt all southbound Application Program Interface (API) management-plane messages using a FIPS-validated cryptographic module.
Description
Discussion Text
An SDN controller can manage and configure SDN-enabled devices using protocols such as SNMP and NETCONF. If an SDN-aware router or switch received erroneous configuration information that was altered by a malicious user, interfaces could be disabled, erroneous IP addresses configured, services removed—all resulting a network disruption or even an outage. Hence, it is imperative to secure the management plane by encrypting all southbound API management-plane traffic or deploying an out-of-band network for this traffic to traverse.
