Just like a physical lock, a mistake when setting up a cloud service is usually hidden. You will typically only become aware of the mistake after a security incident. The provider is not responsible for the customer’s mistakes. This is called the ‘shared responsibility model.’ AWS, Azure, and Google Cloud all provide a secure operation, network, and storage infrastructure. Configuration mistakes continue to be one of the main causes of breaches in 2026. An incorrectly configured storage bucket or exposed API can give attackers the keys to the data. As Cloud deployments continue to grow in their size and in their complexity, so do the potential for configuration errors. This article will analyze the persistent issues caused by cloud misconfigurations, the common configuration errors made by organizations, and how organizations can improve their cloud security.

What Is Cloud Misconfiguration?

A Cloud misconfiguration is a security mistake made by the team deploying the configuration that exposes data, systems, or control mechanisms. These mistakes occur at the configuration level and are not bugs in Cloud services. Consider the office front door. The lock works perfectly. The cloud misconfiguration occurred because the lock was never engaged.

Due to the widespread cloud configuration mistakes resulting in sensitive data exposure, CISA mandated all federal agencies to secure their cloud environments by 2025. If these agencies, who are required to be the most secure, have configuration issues, then we know how difficult and widespread the problem can be.

Common Cloud Configuration Mistakes Resulting in Data Breaches

Configuration mistakes can be due to many factors, but these days the most common are velocity and the complex nature of configuration.

The Cloud Is Faster than Security

Thanks to the ease of cloud computing, development teams can spin up new services, databases, and storage quickly. These often take just minutes. Resources are provisioned automatically based on the needs of the business, but not of security. IT-unsophisticated insiders are capable of implementing embarrassingly open or overly permissive roles and buckets.

Configuration shift is the natural result of this. The settings applied to a system at the time of deployment are initially correct, but quickly become incorrect or in violation of applicable policies. The system, team, and the environment evolve. Eventually, no one checks back.

Growing Complexity of Cloud Environments

Modern organizations typically implement a vast array of Cloud services, including AWS, Azure, GCP, as well as a Private Cloud. A cloud vulnerability assessment helps organizations maintain visibility into security weaknesses across cloud assets.

Each Cloud Service has:

• Different security settings 
• Unique access control models 
• Separate monitoring tools 
• Platform-specific configurations

Managing security in multiple environments is virtually impossible. When the infrastructure of a Cloud Service provider grows, administrators may ignore important security settings or implement incorrect configurations. The complex hybrid and multi-cloud architectures create opportunities for oversights.

Default Settings Remain Insecure

Cloud providers offer defaults to facilitate and expedite the developer and user experience, not to secure their services. AWS S3 buckets were previously set to be completely public by default. Until a public misconfiguration was fixed in 2021, Microsoft’s Power Apps left table permissions set to the public, exposing 38 million records across 30+ organizations. Most IT professionals are not specialists in security. They are satisfied with defaults, and leave the settings alone. They deploy as quickly as possible and move on.

Multi-Cloud Compounds Complexity

Over three-fourths of organizations have more than one cloud provider. This increases the risks of misconfiguration. Each cloud provider- AWS, Azure, Google Cloud- has its own unique user interface and set of terminology and permission models. A security engineer with extensive knowledge of AWS may make configuration errors when setting up Azure for the first time. This is due to the inherent differences in the cloud services.

Two-thirds of the organizations surveyed said maintaining consistent security controls across cloud services is difficult, and just over 45% said they lack adequate staff to address the challenges of a multi-cloud environment. The effect of multiplying complexity across three cloud services does not increase risk by a factor of three; it increases the risk exponentially.

Excess User Permissions

A lot of organizations have broad user permissions. Employees, contractors, and service accounts are all provided permissions beyond what is needed to perform their job responsibilities. These accounts are gold mines for attackers.

Common issues include:

• Shared administrator accounts 
• Unused privileged credentials 
• Overly permissive IAM roles 
• Lack of role-based access controls

Role-based access controls (RBACs) are lacking in many organizations. When RBACs are inappropriate and permissive, the resources are left at risk.

Nobody Is Keeping an Eye on Everything

32% of cloud resources go unmonitored and have a significantly high average of 115 vulnerabilities.

In cloud environments with thousands of resources, many are left unused and forgotten. These resources remain exposed unless they are monitored continuously. An average configuration issue takes 180 days for detection. In that time, an attacker can manipulate your environment, take your data, and disguise their tracks, all before you know there is a problem. Here cloud pentesting should be used to figure out the risks. Cloud penetration testing emulates real-world attack scenarios to evaluate how attackers might exploit weaknesses within a cloud environment.

Real Breaches Caused by Cloud Misconfiguration

Cloud misconfigurations have been behind many major data breaches in recent years.

Automotive Industry: 2.15 Million Users Exposed for Almost 10 Years

An automotive manufacturer exposed the personal data of 2.15 million connected vehicle users due to cloud configuration issues. User information, personal data, and location details remained publicly accessible for nearly a decade before the issue was discovered. The incident highlighted how unnoticed cloud misconfigurations can persist for years.

Enterprise Software Industry: 38 Million Personal Records Exposed Across 47 Organizations

A cloud application platform exposed more than 38 million personal records after a configuration error made sensitive data publicly accessible by default. The affected data included names, email addresses, and phone numbers across 47 organizations, including government agencies and large enterprises.

Cloud Data Platform Industry: 165 Organizations Impacted by a Single Security Gap

A leading cloud data platform provider experienced a large-scale security incident that affected 165 organizations. The breach was not caused by a major cloud misconfiguration but by missing foundational security controls, particularly multi-factor authentication (MFA). Attackers used stolen credentials to access customer environments, demonstrating that missing protections can be just as dangerous as incorrect configurations.

These incidents show that security risks can arise from missing protections, not just incorrect settings. 

AutoSecT: How it Helps Find Cloud Misconfigurations

Modern cloud environments require continuous monitoring and automated security validation. AutoSecT, Kratikal’s AI-powered vulnerability management platform, helps organizations strengthen cloud security through Cloud Security Posture Management (CSPM). The platform also enables automated vulnerability scanning with scheduled assessments across web, mobile, API, and cloud assets.
