Generating attack graphs in agile security platforms
Implementations of the present disclosure include providing graph data defining a graph that is representative of an enterprise network, the graph including nodes and edges between nodes, each node representing an asset within the enterprise network, and each edge representing one or more lateral attack paths between assets in the enterprise network, determining, for each node, an incoming value based on attributes of a set of incoming edges and an outgoing value based on attributes of a set of outgoing edges, the attributes including a number of edges and semantic types of the edges, at least one cardinality value of each node being determined based on one or more of the incoming value and the outgoing value of the node, receiving input representative of filter parameters, generating a sub-graph based on attributes of the nodes and the filter parameters, and displaying, by the visualization platform, the sub-graph in a display.

determining, for each node, an incoming value based on attributes of a set of incoming edges and an outgoing value based on attributes of a set of outgoing edges;
generating, by the visualization platform, a sub-graph representing at least a portion of the graph based on attributes of the nodes and one or more filter parameters; and
displaying, by the visualization platform, the sub-graph in a display.

10. The method of claim 1 , wherein each graph is associated with a target within the enterprise network, the target being selected based on a disruption occurring in response to an attack on the target.
11. The method of claim 10 , wherein the disruption is based on one or more metrics, the one or more metrics comprising loss of technical resources, physical losses, disruption in services, and financial losses.
12. A non-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for security of enterprise networks, the operations comprising:
providing, by a visualization platform, graph data defining a graph that is representative of an enterprise network, the graph comprising nodes and edges between nodes, each node representing an asset within the enterprise network, and each edge representing at least a portion of one or more lateral attack paths between assets in the enterprise network;
