What Is Cloud Infrastructure Security? Risks and Best Practices

Cloud infrastructure has become the backbone of modern businesses. From storing sensitive customer data to running critical applications, more organizations are shifting workloads to the cloud for its speed, scalability, and cost benefits. According to McKinsey, cloud adoption could generate $3 trillion USD in value by 2030 for Fortune 500 companies.

But with this growth comes risk. The more businesses rely on cloud platforms, the more attractive they become to attackers exploiting misconfigured storage, exposed credentials, weak access controls, or vulnerable workloads.
Understanding cloud infrastructure security and implementing best practices is essential to keep threats at bay and maintain business continuity.

What Is Cloud Infrastructure Security?

Cloud infrastructure security is the set of policies, tools, and practices designed to protect the physical and virtual components of cloud environments. This includes compute resources, storage, networking, and virtualization layers across IaaS, PaaS, and SaaS platforms.

Essentially, it’s a subset of cloud security focused on securing the systems that power cloud-based operations. Effective cloud infrastructure security also supports cloud security posture management (CSPM), giving organizations visibility and control as environments scale. Whether using AWS, Azure, Google Cloud, or private on-premise setups, securing the infrastructure you control is critical.

Why Cloud Infrastructure Security Matters

As more critical data moves to the cloud, risk exposure increases. The 2025 Thales Cloud Security Study found that 68% of organizations reported a rise in direct cloud infrastructure attacks targeting sensitive information.

Despite the growing volume of sensitive cloud data, only a fraction is fully protected. Approximately 54% of cloud data is sensitive, yet just 8% of organizations secure more than 80% of it. Mismanaged or unencrypted data makes cloud systems a prime target for cyberattacks.

Cloud security is further complicated by the rise of multi-cloud setups, fragmented identities, tool sprawl, and rapid AI adoption. Organizations need proactive strategies to stay ahead of threats and protect both data and operations.

Key Components of Cloud Security Infrastructure

1. Storage Solutions
Secure storage is essential for sensitive data. Encrypt data at rest and in transit, enforce role-based access controls (RBAC), and protect backups to ensure recovery if needed.
2. Databases
Cloud-hosted databases are high-value targets. Enforce encryption, limit privileges, rotate credentials, and secure connections to prevent unauthorized access.
3. Compute Resources
Protect virtual machines, containers, and other compute resources through secure configurations, runtime controls, and strict permission boundaries.
4. Networking
Network security starts at the edge. Isolate traffic, configure firewalls, monitor open ports, and secure APIs to prevent unauthorized entry.
5. Identity and Access Management (IAM)
Implement least privilege access, audit dormant accounts, and enable multi-factor authentication (MFA) to reduce the risk of lateral movement and service abuse.
6. Management and Monitoring Tools
Continuous monitoring and auditing are crucial. Cloud monitoring tools provide visibility, detect misconfigurations, and help maintain a strong security posture.

Cloud Infrastructure Security Risks

Common risks organizations face include:

• Lack of visibility: Difficulty tracking data flows and user access across dynamic cloud environments.
• Misconfigurations: Human errors like exposed storage or incorrect permissions cause a large share of breaches.
• Unsecured remote access: Poorly managed remote connections increase exposure.
• Incomplete logging: Without comprehensive audit trails, response and recovery efforts are slowed.

6 Best Practices for Cloud Infrastructure Security

1. Update and Patch Regularly – Keep VMs, containers, and applications updated to reduce vulnerability exposure.
2. Use Least Privilege Access – Limit user permissions to reduce attack surfaces.
3. Encrypt Data Everywhere – Secure data at rest, in transit, and in use with strong encryption protocols.
4. Monitor Continuously and Audit Regularly – Use real-time monitoring and audits to detect threats early.
5. Back Up and Test Recovery Processes – Schedule automated backups and test them to ensure reliable recovery.
6. Educate Employees – Train staff on phishing, access management, and cloud security best practices.
