Cloud computing has reshaped cybersecurity by introducing complex access controls, heightened API security risks, and the challenges of managing multiple cloud environments. The scale and complexity of access control rules have increased significantly, making it easier for administrators to overlook important settings. Additionally, the proliferation of APIs in cloud environments has created new security vulnerabilities. Finally, multicloud architectures complicate monitoring and securing resources due to varying configurations and the sheer number of services involved.

Cloud computing has opened the door to new types of cybersecurity attacks, such as denial-of-wallet attacks, where attackers exploit cloud resources to inflate costs for their victims, and cryptojacking, where compromised infrastructure is used to mine cryptocurrency at the expense of the victim. These attacks leverage the scalable nature of cloud environments, making them potentially more damaging than similar attacks in traditional on-premises settings.

Managing security in cloud environments is more complex due to the lack of a defined network perimeter, the need to monitor multiple cloud platforms, and the diverse security tools required for different services. Unlike traditional setups where applications were housed on on-premises servers with clear boundaries, cloud environments expose workloads to the internet, increasing vulnerability. Additionally, the differences in configurations across cloud providers complicate the identification and management of security risks.
