Unpredictability (or randomness) plays a critical role in securing connections between entities. Entropy is a generator of randomness. As a rule, entities with more randomness have a more secure connection. A lack of entropy can have a negative impact on security and performance.
Trellix devices must have adequate entropy to generate keys for secure SSL and SSH communication. Physical Trellix appliances have a built-in source of high-quality entropy. Virtual appliances do not have a built-in source, so they continually obtain entropy information from a centralized, upstream DTI entropy server.
