A cloud data breach can have devastating consequences, including financial losses, reputational damage, legal liabilities and operational disruptions. In fact, as IBM reported, 82% of breaches in 2024 involved data stored in the cloud and cost enterprises an average of $4.88 million.
Security management in cloud computing is becoming a top concern for most organizations, which is understandable given the 75% increase in incidents in the past year alone, according to CrowdStrike. [...] Cloud security management is the practice of securing cloud-based data, applications and infrastructure through coordinated policies, controls and continuous oversight.
Cloud environments introduce distinct security challenges such as misconfigurations, identity misuse and limited visibility that require approaches beyond traditional IT security models. [...] ### 1. Misconfigurations and poor access control
Misconfigurations in cloud resources are a leading cause of data breaches. Common misconfigurations include publicly accessible storage buckets, improperly configured security groups and overly permissive Identity and Access Management (IAM) policies.
### 2. Insider threats and unauthorized access

Cloud data security is a discipline, a market category, and a class of solutions, including Data Security Posture Management (DSPM), that encompasses the policies, controls, and technologies used to protect data stored in or transmitted through cloud environments from unauthorized access, data breaches, exfiltration, and accidental exposure.
This definition has three operational components. [...] Cloud data security protects data at rest, in transit, and in use across cloud storage and compute services through encryption with customer-managed keys, least-privilege Identity and Access Management (IAM) policies, and continuous monitoring. [...] The compliance challenge specific to cloud environments is that configuration drift can occur without any deliberate action by the security team. Auto-scaling events can create EC2 instances with default security group rules. Developers can modify S3 bucket policies through the console without triggering a change management process. Automated compliance assessment that runs continuously and alerts on configuration drift is the only operationally sustainable approach at cloud scale.

Data security in cloud computing involves combining technologies, procedures, and policies to protect cloud systems, applications, and data.
Data security is essential at all stages of the cloud computing process and data lifecycle, including development, deployment, migration, and management. Cloud environments pose various data security risks that your security strategy must address. The main risk is a data breach or attack. [...] Cloud computing introduces new threats in addition to those affecting on-premise infrastructure. Common data threats in the cloud include:
Another key consideration in cloud environments is the shared responsibility model. On-prem security is the organization’s sole responsibility, but in the cloud, you share security responsibilities with the vendor. Navigating shared security controls can be tricky, and the shared responsibility differs between cloud models.

### Shadow IT
Shadow IT—unvetted software or services implemented by employees without IT approval—introduces vulnerabilities that threat actors can exploit, making cloud data security even more challenging.
Key risks include:
Weak security controls: Unauthorized cloud services lack the same security measures as approved ones, increasing the risk of data breaches.
Human error: Employees may unintentionally share or expose sensitive data stored in unauthorized cloud services. [...] Data access within and outside the network may be invisible, which can significantly impact cloud security. With a clear view of who is accessing your data, from where, and how frequently, safeguarding your assets becomes more manageable, especially in multi-cloud and hybrid scenarios.
A lack of visibility can lead to:
Data breaches: Without visibility, you can't detect unauthorized access, leading to potential breaches. [...] # What is Cloud Data Security? Risks and Best Practices
##### Key takeaways
Cloud data security is about unifying visibility across fragmented environments where sensitive data moves unpredictably between services, regions, and identities.
The shared responsibility model creates a dangerous gray zone: Cloud providers secure infrastructure, but customers own data protection. Most breaches exploit this gap.

Misconfigurations in cloud environments are among the most common and critical security risks. These occur when cloud resources, such as storage buckets, databases, or virtual machines, are set up with weak security controls or improper access permissions. Examples include leaving storage buckets open to the public, not enabling encryption, or failing to configure identity and access management (IAM) settings correctly. These misconfigurations can expose sensitive data and cloud infrastructure [...] In cloud environments, IAM poses a major security risk by failing to properly control and monitor who has access to critical cloud resources. IAM is essential for defining user roles, permissions, and authentication protocols across cloud services. Weak IAM practices — such as insufficient role-based access controls (RBAC), lack of multi-factor authentication (MFA), or failure to enforce the principle of least privilege — can leave cloud systems vulnerable to unauthorized access. [...] In cloud environments, data breaches often occur when misconfigurations, weak access controls, or inadequate encryption expose sensitive information to unauthorized parties. Unlike traditional on-premise breaches, cloud data breaches can involve multiple layers of shared responsibility, where both the cloud provider and the user play a role in securing the environment.

1. Theft or loss of intellectual property
An outstanding 21% of data uploaded by companies to cloud-based file management services contain sensitive data. The analysis that was done by Skyhigh found that companies face the risk of having their intellectual property stolen. [...] Regardless of the great advantages, saving a firm’s workloads to a cloud service that is publicly hosted exposes the organization to new data security risks which cause unease for some firms’ IT departments and clients.
With more and more data and software moving to the cloud, unique info-security challenges crop up. Here are the top cloud computing security risks that every firm faces.
## Cloud Security Risks [...] To effectively mitigate the security risks brought by unmanaged cloud usage, firms need to understand the data that is being uploaded to cloud servers and who is uploading the data. The cloud storage and sharing services are here to stay, and firms must be able to balance the risks posed by using the service.
The following steps will aid business decision-makers and enterprise IT managers to analyze cloud security of company data;

Cloud security encompasses the technologies, applications, controls, and policies that protect people, data, and infrastructure from cyber-attacks and compliance risks on cloud computing platforms. It involves a comprehensive set of security measures designed to address both external and internal security threats to organizations, including controlling security, compliance, and other usage risks of cloud computing and data storage. [...] By focusing on these key best practices, organizations can significantly improve their cloud security posture and better protect their valuable assets and data in the cloud environment.
### Cloud Security Risks & Challenges
Even with modern advancements in today’s cloud security, these systems still face several risks, challenges, and limitations. Some of the most common challenges include: [...] Enterprises face growing cloud compliance risks in the face of ever-changing cybersecurity regulations. Government and industry regulations require you to know where your data is in the cloud and how it is being shared. The European Union General Data Protection Regulation (GDPR) affects millions of organizations. That’s why developing a plan to comply with the new rules is critical for all organizations.
