Abstract

Embodiments provide a system and method for constructing a graph-based model for optimizing the security posture of a composed system. During operation, the system constructs a multi-layer graph for a system with a plurality of components, wherein the multi-layer graph comprises a configuration subgraph, a vulnerability subgraph, and a dependency subgraph. The system constructs the multi-layer graph by the following. The system generates nodes in the configuration subgraph, including: nodes in a first class which encode information associated with a configuration parameter for a respective component, wherein the encoded information includes a name, a default value, a range of values, and a data type; and nodes in a second class which encode value assignments for configuration parameters and relationships between configuration parameters. The system generates nodes in the vulnerability subgraph based on known vulnerabilities associated with a component, bad security practices, and best security practices.
