Cloud Security is the collection of tools, techniques and technologies that prevent unauthorized access to data, apps and infrastructure in cloud environments. It includes the use of cloud-native encryption tools to protect sensitive data in transit, and identity and access management (IAM) to ensure users only have the permissions they need. It also includes monitoring and securing the physical networks, routers, power and cabling that make up the cloud environment.

Since the cloud lacks traditional network perimeters, a new set of security challenges arises. Most of these threats are aimed at exploiting people, which is why strong cloud security is increasingly important for organizations. It can protect against expensive breaches, reputational damage and legal penalties. It can also improve employee productivity and reduce costs by making it easier to work from home or on the go.

In addition to a Zero Trust approach, which requires all access attempts — whether from the inside or outside — to be verified and validated, Cloud Security also includes techniques such as Least Privilege Access, which restricts user and device privileges to what is required for the task at hand, and Micro-Segmentation, which divides cloud environments into smaller segments to limit lateral movement by attackers should they gain access. Finally, it includes the use of security information and event management (SIEM) to monitor for anomalous activity and potential vulnerabilities. These are all part of a comprehensive cloud security strategy that should be implemented alongside a cloud deployment model (whether it’s Infrastructure as a Service, Platform as a Service or Software as a Service).
