Abstract: The node exposure score generator and the attack path modeling component are configured to cooperate to analyze the actual detected vulnerabilities that exist for that network node in the network, the importance of network nodes in the network compared to other network nodes in the network, and the key pathways within the network and the vulnerable network nodes in the network that a cyber-attack would use during the cyber-attack in order to provide an intelligent prioritization of remediation actions to remediate the actual detected vulnerabilities for each network node from the network protected by a cyber security appliance.
