SYSTEM AND METHOD FOR MODELING A SHARED RESOURCE IN A MULTI-LAYER REASONING GRAPH BASED ON CONFIGURATION SECURITY

Embodiments provide a system and method for modeling a shared resource in a multi-layer reasoning graph based on configuration security. During operation, the system can obtain a multi-layer graph for a system with a plurality of components that can include a set of subgroups of components. The system can generate, based on the multi-layer graph, an abstract component to represent a shared resource model for a respective subgroup of components. The shared resource model can be associated with a set of resource constraints. The system can generate a set of values for resource configuration parameters that satisfy the resource constraints. The system can map the shared resource model to a respective component and can then determine, based on the mapping and the set of values for the resource configuration parameters, a set of values for the component configuration parameters thereby facilitating optimization of a security objective function.
