Cybersecurity threat modeling and analysis with text miner and data flow diagram editor

A computing method, comprising:

• at one or more processors of a cybersecurity computing system:
• mining unstructured data from unstructured text sources to extract features of a target computer system;
• processing the extracted features to identify system elements of the target computer system and interrelationships between the identified system elements, and to identify candidate system-related candidate properties of the system elements;
• populating a system element template for each identified system element with the system-related candidate properties for that element;
• facilitating a display of the system-related candidate properties for each system element in a data flow diagram region;
• receiving a system property adoption user input for each system-related candidate property of each identified system element;
• generating data flow diagrams comprising each identified system element having the system-related candidate properties adopted according to the system property adoption user input;
• and
• facilitating a presentation of the generated data flow diagrams in a graphical user interface.

A computing method, comprising:

• at one or more processors of a cybersecurity computing system:
• mining unstructured text sources to extract features of one or more cybersecurity threats;
• processing the extracted features to identify cybersecurity threats associated with the extracted features and interrelationships between the cybersecurity threats and system elements of a target computer system;
• populating a threat template for each identified cybersecurity threat with threat-specific candidate properties for that threat;
• displaying the threat-specific candidate properties in a threat template editor region of a graphical user interface;
• receiving a threat property adoption user input for each of the threat-specific candidate properties for each identified cybersecurity threat;
• generating a set of cybersecurity threat characteristics comprising a list of cybersecurity threats and the cybersecurity threat characteristics for each of the cybersecurity threats based on the threat property adoption user input;
• and
• displaying the list of cybersecurity threats having the cybersecurity threat characteristics in the graphical user interface.
