Implementations are directed to receiving analytical attack graph (AAG) data representative of one or more AAGs, each AAG representing one or more lateral paths between configuration items within an enterprise network, calculating, for each configuration item in a set of configuration items, a process risk value for each impact in a set of impacts achievable within the configuration item, for a first impact, a first process risk value being calculated based on a multi-path formula in response to determining that multiple paths in the AAG lead to the first impact, and, for a second impact, a second process risk value being calculated based on a single-path formula in response to determining that a single path in the AAG leads to the second impact, and determining that at least one process risk value exceeds a threshold process risk value, and in response, adjusting one or more security controls within the enterprise network.

Process risk calculation based on hardness of attack paths

Implementations of the present disclosure include providing a state graph representative of a set of action states within a network, each action state representing an attack that can be performed by an adversary within the network, determining a path stealthiness value for each attack path of a set of attack paths within the network, path stealthiness values being determined based on a mapping that maps each action state to one or more technique-tactic pairs and one or more security controls, determining a path hardness value for each attack path of the set of attack paths within the network, path hardness values being determined based on a state correlation matrix that correlates action states relative to each other, and a decay factor that represents a reduction in effort required to repeatedly perform an action of an action state, and selectively generating one or more alerts based on one or more of path stealthiness values and path hardness values.
