A number of major carriers have suffered high-impact IT events in the past several months. Estimates of losses in these cases have exceeded £100m. This is on top of (no doubt significant) remedial costs, reductions in share price and reputational damage.
Such high-impact events are, in theory, unlikely to occur—the result of a series of unlikely events which when taken together have a catastrophic impact. Unfortunately for corporates, the probability of a high impact IT event is increasing. This is partly due to the increasingly interconnected and complex nature of IT infrastructures but also due to heightened cybersecurity risks. Failures tend not to be not localised to a particular geography or business but have global reach.
We advise airlines to consider and revisit their current business continuity and disaster recovery (BCDR) arrangements. In our experience, the reality of BCDR arrangements often falls below the stated requirements or capabilities of such solutions, whether provided by third-party IT providers or in-house.
