What is cloud security?
Cloud security refers to the cybersecurity policies, best practices, controls, and technologies used to secure applications, data, and infrastructure in cloud environments. In particular, cloud security works to provide storage and network protection against internal and external threats, access management, data governance and compliance, and disaster recovery.
Cloud computing has become the technology of choice for companies looking to gain the agility and flexibility needed to accelerate innovation and meet the expectations of today’s modern consumers. But migrating to more dynamic cloud environments requires new approaches to security to ensure that data remains secure across online infrastructure, applications, and platforms.

Cloud security is the set of cybersecurity measures used to protect cloud-based applications, data, and infrastructure. This includes applying security policies, practices, controls, and other technologies like identity and access management and data loss prevention tools to help secure cloud environments against unauthorized access, online attacks, and insider threats.
How does cloud security work?
Here’s a look at how this typically works:
Why is cloud security important?
Cloud security risks and challenges
Lack of visibility
Only an integrated cloud-based security stack is capable of providing the centralized visibility of cloud resources and data that is vital for defending against breaches and other potential threats. Cloud security can provide the tools, technologies, and processes to log, monitor, and analyze events for understanding exactly what’s happening in your cloud environments.
Cloud security allows you to consolidate protection of cloud-based networks for streamlined, continuous monitoring and analysis of numerous devices, endpoints, and systems. It also enables you to centrally manage software updates and policies from one place and even implement and action disaster recovery plans.
With cloud security, you don’t have to pay for dedicated hardware to upgrade your security or use valuable resources to handle security updates and configurations. CSPs provide advanced security features that allow for automated protection capabilities with little to no human intervention.
The best cloud computing providers will provide data security by design, offering strong access controls, encryption for data at rest and in transit, and data loss prevention (DLP) to secure your cloud data wherever it’s located or managed.
Cloud providers go to great lengths to comply with both international and industry compliance standards, often undergoing rigorous independent verifications of their security, privacy, and compliance controls.
Advanced threat detection
Reputable CSPs also invest in cutting-edge technologies and highly skilled experts to provide real–time global threat intelligence that can detect both known and unknown threats in the wild and in your networks for faster remediation.
