For FOX61x NE related security deployment guidelines refer to [1KHW028641] FOX61x Cybersecurity Deployment Guideline published on Hitachi Energy Publisher via https://publisher.hitachienergy.com (registration required).

When connecting the FOX61x NEs with NE authentication enabled using fingerprint, a finger print verification can be done to make sure the fingerprint used to connect to the NE is correct. If the fingerprint configured in the NMS differs from the fingerprint provided by the NE, the client will warn the operator via a security alert. Such an alert may indicate that a man-in-the-middle attack is being carried out.
