SOLVE-IT: A proposed digital forensic knowledge base inspired by MITRE ATT&CK

This work presents SOLVE-IT (Systematic Objective-based Listing of Various Established (Digital) Investigation Techniques), a digital forensics knowledge base inspired by the MITRE ATT&CK cybersecurity resource. Several applications of the knowledge-base are demonstrated: strengthening tool testing by scoping error-focused data sets for a technique, reinforcing digital forensic techniques by cataloguing available mitigations for weaknesses (a systematic approach to performing Error Mitigation Analysis), bolstering quality assurance by identifying potential weaknesses in a specific digital forensic investigation or standard processes, structured consideration of potential uses of AI in digital forensics, augmenting automation by highlighting relevant CASE ontology classes and identifying ontology gaps, and prioritizing innovation by identifying academic research opportunities. The paper provides the structure and partial implementation of a knowledge base that includes an organised set of 104 digital forensic techniques, organised over 17 objectives, with detailed descriptions, errors, and mitigations provided for 33 of them. The knowledge base is hosted on an open platform (GitHub) to allow crowdsourced contributions to evolve the contents. Tools are also provided to export the machine readable back-end data into usable formats such as spreadsheets to support many applications, including systematic error mitigation and quality assurance documentation.
