Until there are proper incentives for executives (e.g. full asset seizure and mandatory multi-year community service in roles such as junior janitor, junior hospice care specialist, live-in support for late stage alzheimer's patients) that require them to take ownership and responsibility for their actions (or lack of thereof), this will continue.

Just look at the 2017 Equifax breach in the US:

Wikipedia background:

An Equifax internal audit in 2015 showed that there was a large backlog of vulnerabilities to patch, that Equifax wasn't following its own timescales on patching them, that IT staff did not have a comprehensive asset inventory, that Equifax didn't consider how critical an IT asset was when prioritising patches, and that the patching process worked on an 'Honour system'. The report set out actions to improve the process, but the time of the breach, two years later, many of them had not been completed.

Equifax press release states that CIO and CSO can now enjoy retirement:

As part of the company's ongoing review of the cybersecurity incident announced September 7, 2017, Equifax Inc. (NYSE: EFX) today made personnel changes and released additional information regarding its preliminary findings about the incident.

The company announced that the Chief Information Officer and Chief Security Officer are retiring.

Richard Smith, the CEO under whose watch this happened, got to retire at the ripe old age of 57 and got a nice bonus of $90 M

Richard Smith, 57, is the third Equifax executive to retire under pressure following the company's massive data breach revealed earlier this month, putting the personal information of as many as 143 million people at risk.

But the CEO is still set to collect about $72 million this year alone (including nine months' worth of his $1,450,000 salary), plus another $17.9 million over the next few years. That's when the rest of Smith's stock compensation hits a few important milestones or "vests," allowing Smith to essentially put it in his bank account. Altogether, it adds up to a total potential paycheck of more than $90.1 million, according to Fortune's calculations based on Equifax securities filings.
