1. A system for dynamically updating firewall rules for a vehicle network, the system comprising:
a processor; and
a memory in communication with the processor, the memory having a cyber health engine module including instructions that, when executed by the processor, cause the processor to:
request health status information from one or more nodes of the vehicle network when at least one of the following occurs: booting of the system, periodically determined by timer and/or event, and after observing an anomaly by the system or any other intrusion detection system,
receive the health status information from the one or more nodes of the vehicle network,
calculate a risk factor for the one or more nodes of the vehicle network based on the health status information, and
in response to determining that the risk factor for the one or more nodes of the vehicle network indicates increased risk, update the firewall rules to address the increased risk.
