Process Modelling and Analysis Case study 3

Extract from Office of Victorian Information Commissioner, (2020), Risk Scenario 2 Legacy System-Case Study, Available at: https://ovic.vic.gov.au/data-protection/risk-scenario-2-legacy-systems-case-study/ , Accessed 27 July 2022

The Department of Innovation was using a legacy system to extract data and produce reports that provided mission critical information about the innovation projects the department was managing. Workers had been complaining about a number of faults with the legacy reporting system. IT claimed that vendor support was no longer available for the system, and patches were infrequent and costly. The system is a key dependency to the critical business activity of reporting, despite being known as out of date by the user base. No integration between the source data systems and the reporting capability currently existed.

Furthermore, there was only one person in the organisation who knew how to manage the system. The legacy system was difficult to backup and recover. Ransomware hit the department and the data residing on the legacy system was no longer accessible. With no redundancy options, no way to recover and the only person who understood the environment away, the department found itself in a bind.
