Every week, security teams around the world discover cloud environments with improperly configured access—a problem known as cloud misconfiguration or Shadow IT. These aren't usually the work of seasoned hackers; they're just simple errors with massive consequences.
A recent example that caught headlines was a major financial services firm, Ernst & Young (EY). Their simple cloud storage misconfiguration left a 4-terabyte SQL server backup file exposed to the public internet. This event proves that even organizations with multi-million dollar security budgets are vulnerable when human error enters the equation. It's an industry-wide headache, showing us that the easiest mistakes are often the ones that cause the most damage.
The issue boils down to this: internal complexity and Shadow IT can be just as dangerous as an external adversary. In this blog, we'll explore how a "one-click" mistake happens and how to implement continuous security posture management to prevent it.
The vulnerability in the recent high-profile case was a misconfigured Access Control List (ACL) on a cloud storage container, which rendered a sensitive file public. This basic mistake clearly shows us the core issues behind almost all cloud misconfigurations: the Complexity Gap and the Visibility Gap.
The "Complexity Gap" explains how the "one-click" mistake happened. This is a classic breakdown in the Cloud Shared Responsibility Model.
While the cloud provider secures the physical infrastructure, the customer retains full, non-negotiable responsibility for securing their own data, configurations, and access management within that cloud.
In the race for agility, a quick choice by an engineer to make a file public, even temporarily, can instantly bypass all strategic corporate security controls. The relentless pace of development and the sheer number of settings will always move too fast for people to manually check everything on time. That’s why relying on human review alone for cloud security is failing.
A technical mistake is dangerous, but it becomes a crisis when it happens in a blind spot. This is where the "Visibility Gap" becomes the primary accelerator.
The misconfigured asset was found to be "unconnected" to the organization's global security systems—the textbook definition of Shadow Infrastructure. Whether it's an inherited asset from an M&A deal, a forgotten test environment, or an unauthorized cloud account, invisibility makes the mistake worse. If an asset isn't reporting to the Security Operations Center (SOC) or in the central inventory, the human error can sit there forever. This proves a fundamental rule of infrastructure security: if you can't see it, you can't protect it.
CISOs must take steps today to ensure a similar exposure does not occur. The answer isn't just writing more rules; it's building automated enforcement into your operations and backing it up with security experts.
The shift to security requires automated cloud security management—a practice often referred to as adopting Cloud-Native Application Protection (CNAP) principles. This modern approach relies on key capabilities to stop human error from escalating:
Even when organizations own the necessary security technology (like Microsoft E5 suites), the human resource challenge remains. Because a simple oversight in policy configuration can still lead to exposure, expert management and dedicated staff are crucial.
SecureOps Co-owned Managed Detection and Response (MDR) provides immense value in this area. An MDR partner provides the staff and expertise to continuously run and tune your security tools—ensuring 'one-click' errors are detected and fixed fast, not days later. We eliminate the reliance on manual oversight that creates the Complexity Gap.

The only true defense against human error is automation backed by expert management.
For organizations running a Microsoft E5 license, you already own the core components for security automation within Microsoft Defender XDR (including XDR, VM, and posture management capabilities). SecureOps specializes in leveraging your existing investment—tuning and managing your E5 stack to provide immediate, robust protection.
If your organization is a Microsoft-dedicated environment, there is a substantial business case to consolidate your security technology stack on the E5 suite of solutions. Learn how this consolidation can reduce vendor sprawl and maximize your license investment on our dedicated blog post.
