Many office and web based applications, both commercial and bespoke use SQL servers of varying flavours – you or your cyber security consultant should know if your organisation is dependent on a Microsoft SQL server and what actions have been taken to protect it.

My advice: Either you or your IT support need to check whether these issues impact your systems. You need to have a master document that details your systems, hardware, software, online, networks, back-ups, suppliers etc – so when cyber security (or operational) issues arise you and your support teams can quickly check if you are affected. From there you can take fast, effective action.
