Cloud network security refers to the tools, policies, and practices used to protect data, applications, and services that operate in cloud environments. As organizations increasingly rely on cloud computing for storage and processing, securing cloud networks has become a critical priority.

Unlike traditional on-premises networks, cloud networks are highly dynamic. Resources can be created, moved, or removed in minutes, which means security must be flexible and automated. Key elements of cloud network security include identity and access management (IAM), encryption, firewalls, intrusion detection systems, and continuous monitoring. These controls help ensure that only authorized users can access resources and that data remains protected both in transit and at rest.

A shared responsibility model is central to cloud security. Cloud service providers secure the underlying infrastructure, while customers are responsible for protecting their data, configurations, and user access. Misconfigurations, such as open storage or weak permissions, are among the most common security risks.

Effective cloud network security combines strong technical controls with good practices, including regular audits, updates, and employee awareness. When done correctly, it enables organizations to benefit from the scalability and efficiency of the cloud without sacrificing safety.
