The security of the block producing node is paramount. We operate a security program that spans the entire organization. We strive to follow NIST best practices so that the entire organization provides a robust front against threats of all kinds.
Our infrastructure uses Google Load Balancer which protects our nodes from DDoS and allows TCP termination on hardware devices. The connections are terminated at the edge and only valid connections are allowed to connect to the core. A whitelist firewall only allows traffic passing through the core network if it is explicitly allowed. We periodically conduct penetration tests against our own infrastructure so that we maintain the highest level of security for you, the token-holder.
