Claim 14:
15. A system comprising:
a plurality of nodes within an internal network, each comprising one or more hardware processor and configured to receive external network traffic from an outside network;
an operator node of the internal network, the operator node configured to:
determine whether external traffic received by the internal network introduces an above-threshold level of risk of malicious action to the internal network;
responsive to determining that the external traffic introduces the above-threshold level of risk of malicious action to the internal network:
identifying a set of the plurality of nodes corresponding to the external network traffic that introduces the above-threshold level of risk of malicious action; and
isolating the set of nodes by instructing a DNS server of the internal network to prevent resolution of DNS requests for IP addresses corresponding to the set of nodes until a simulation of external network traffic indicates that the external network traffic introduces a below-threshold level of risk of malicious action to the internal network.
