CIO Brief: If Microsoft Can Misconfigure Azure, So Can You
Retrospective: this article looks back at events from January 2020, written in 2026 with the benefit of hindsight.
The short version: In 2020, Microsoft disclosed that a customer support database had been left exposed to the internet after a network setting change. If the company that builds Azure can make this mistake, so can any organization running on it.
Why misconfiguration is the main cloud risk
Most cloud data exposures aren't caused by sophisticated attacks. They come from settings changed by well-meaning people: a firewall rule opened for testing, a database made public to troubleshoot. In a large environment, those changes happen daily.
The business impact
- Data exposure discovered by outsiders scanning the internet.
- Notification costs and regulatory scrutiny.
- Reputational damage, even when the data is limited.
Questions to ask your team
- Which of our cloud databases and storage services are reachable from the internet?
- Are risky settings blocked automatically, or only flagged after the fact?
- How quickly would we notice if someone opened a database to the internet?
- Do we review network rule changes?
What good looks like
Data services reachable only through private networks, automated policies blocking public exposure, alerts on risky changes and documented exceptions.
The decision
Ask your team to report the number of cloud data services with public network access, and a plan to reduce it to only those with a documented business need.
