Abstract: To analyze open-source code at a large scale, a security domain graph language (“SGL”) has been created that functions as a vulnerability description language and facilitates program analysis queries. The SGL facilitates building and maintaining a graph database to catalogue vulnerabilities found in open-source components. This graphical database can be accessed via a database interface directly or accessed by an agent that interacts with the database interface. To build the graph database, a database interface processes an open-source component and creates graph structures which represent relationships present in the open-source component. The database interface transforms a vulnerability description into a canonical form based on a schema for the graph database and updates the database based on a determination of whether the vulnerability is a duplicate. This ensures quality and consistency of the vulnerability dataset maintained in the graph database.

Abstract: To analyze open-source code at a large scale, a security domain graph language (“SGL”) has been created that functions as a vulnerability description language and facilitates program analysis queries. The SGL facilitates building and maintaining a graph database to catalogue vulnerabilities found in open-source components. This vulnerability database generated with SGL is used for analysis of software projects which use open source components. An agent which interacts with the vulnerability database can perform a scan of a software project to identify open-source components used in the project and submit queries to the vulnerability database to identify vulnerabilities which may affect the open-source components in the project. Results of the scan are presented to a user in the form of a vulnerability report which indicates vulnerabilities that have been discovered and which open-source components the vulnerabilities affect.
