Preparing for the Next Worldwide Tech Outage

CIOs can take steps now to reduce risks associated with today’s IT landscape
As tech leaders race to bring Windows systems back online after Friday’s software update by cybersecurity company CrowdStrike crashed around 8.5 million machines worldwide, experts share with CIO Journal their takeaways for preparing for the next major information technology outage.
IT leaders should hold vendors deeply integrated within IT systems, such as CrowdStrike , to a “very high standard” of development, release quality and assurance, said Neil MacDonald , a Gartner vice president.
“Any security vendor has a responsibility to do extensive regression testing on all versions of Windows before an update is rolled out,” he said.
That involves asking existing vendors to explain how they write software, what testing they do and whether customers may choose how quickly to roll out an update.
“Incidents like this remind all of us in the CIO community of the importance of ensuring availability, reliability and security by prioritizing guardrails such as deployment and testing procedures and practices,” said Amy Farrow, chief information officer of IT automation and security company Infoblox.
While automatically accepting software updates has become the norm—and a recommended security practice—the CrowdStrike outage is a reminder to take a pause, some CIOs said.
“We still should be doing the full testing of packages and upgrades and new features,” said Paul Davis, a field chief information security officer at software development platform maker JFrog . undefined undefined Though it’s not feasible to test every update, especially for as many as hundreds of software vendors, Davis said he makes it a priority to test software patches according to their potential severity and size.
Automation, and maybe even artificial intelligence-based IT tools, can help.
“Humans are not very good at catching errors in thousands of lines of code,” said Jack Hidary, chief executive of AI and quantum company SandboxAQ. “We need AI trained to look for the interdependence of new software updates with the existing stack of software.”
An incident rendering Windows computers unusable is similar to a natural disaster with systems knocked offline, said Gartner’s MacDonald. That’s why businesses should consider natural disaster recovery plans for maintaining the resiliency of their operations.
One way to do that is to set up a “clean room,” or an environment isolated from other systems, to use to bring critical systems back online, according to Chirag Mehta, a cybersecurity analyst at Constellation Research.
Businesses should also hold tabletop exercises to simulate risk scenarios, including IT outages and potential cyber threats, Mehta said.
Companies that back up data regularly were likely less impacted by the CrowdStrike outage, according to Victor Zyamzin, chief business officer of security company Qrator Labs. “Another suggestion for companies, and we’ve been saying that again and again for decades, is that you should have some backup procedure applied, running and regularly tested,” he said.
For any vendor with a significant impact on company operations , MacDonald said companies can review their contracts and look for clauses indicating the vendors must provide reliable and stable software.
“That’s where you may have an advantage to say, if an update causes an outage, is there a clause in the contract that would cover that?” he said.
If it doesn’t, tech leaders can aim to negotiate a discount serving as a form of compensation at renewal time, MacDonald added.
The outage also highlights the importance of insurance in providing companies with bottom-line protection against cyber risks, said Peter Halprin, a partner with law firm Haynes Boone focused on cyber insurance.
This coverage can include protection against business income losses, such as those associated with an outage, whether caused by the insured company or a service provider, Halprin said.
The CrowdStrike update affected only devices running Microsoft Windows-based systems , prompting fresh questions over whether enterprises should rely on Windows computers.
CrowdStrike runs on Windows devices through access to the kernel, the part of an operating system containing a computer’s core functions. That’s not the same for Apple ’s Mac operating system and Linux, which don’t allow the same level of access, said Mehta.
Some businesses have converted to Chromebooks , simple laptops developed by Alphabet -owned Google that run on the Chrome operating system . “Not all of them require deeper access to things,” Mehta said. “What are you doing on your laptop that actually requires Windows?”

The bank posted unaudited cash earnings for the quarter of A$1.7 billion, down 2% on the average of its prior two quarters
National Australia Bank said that higher credit impairments against business loans contributed to a small fall in its unaudited December quarter cash earnings.
NAB , which is Australia’s second-largest bank by market capitalization, on Wednesday posted unaudited cash earnings for its fiscal first quarter of 1.74 billion Australian dollars, equivalent to about US$1.11 billion.
That was down 2% on the average of its prior two fiscal quarters. NAB did not give a year-earlier comparison.
The lender said that revenue grew by 3% compared with the average of its prior two fiscal quarters. Underlying profit growth of 4% over the same period was offset by higher credit impairment charges and income tax expenses, it added.
NAB, which posted an unaudited quarterly statutory profit of A$1.70 billion, said the A$267 million credit impairment charge included A$152 million of individually assessed charges. Those were mainly against Australian businesses and unsecured retail portfolios, it said.
The individual charges were up by 54% compared with a year earlier. NAB said that it had not altered its economic assumptions and scenario weightings.
“The economic outlook is improving but cost of living and interest rate challenges persisted,” Chief Executive Andrew Irvine said. “While most customers are proving resilient, we have maintained prudent balance sheet settings.”
NAB said it had seen a small decline in net interest margin due to funding costs, lending competition and deposits, partially offset by the benefit of higher interest rates.
On Tuesday, the Reserve Bank of Australia cut the country’s cash rate for the first time since 2020 but warned against expecting subsequent near-term cuts.
NAB is still targeting full fiscal-year productivity savings of more than A$400 million, and for operating expenses to grow by less than 4.5%, Irvine said.
