Abstract: Forensic-ready software systems integrate preparedness for digital forensic investigation into their design. It includes ensuring the production of potential evidence with sufficient coverage and quality to improve the odds of successful investigation or admissibility. However, the design of such software systems is challenging without in-depth forensic readiness expertise. Thus, this paper presents a tool suite to help the designer. It includes a graphical editor for creating system models in BPMN4FRSS notation, an extended BPMN with forensic readiness constructs, and an analyser utilising Z3 solver for satisfiability checking of formulas derived from the models. It verifies the models’ validity, provides targeted hints to enhance forensic readiness capabilities, and allows for what-if analysis of potential evidence quality.
