Cloud Platform and Infrastructure Security refers to the comprehensive set of practices, policies, and technologies designed to protect cloud computing environments and the underlying infrastructure from threats. It encompasses securing the network, data, applications, and identity and access management within cloud services like AWS, Azure, or Google Cloud. This security model operates by implementing layered defenses, continuous monitoring, and robust access controls to safeguard sensitive information and maintain service availability. Adhering to these principles is crucial for preventing data breaches, ensuring compliance, and building trust with users and stakeholders. For instance, configuring security groups to restrict network traffic to only necessary ports is a fundamental aspect of infrastructure security. Unlike general cybersecurity, cloud platform security specifically addresses the shared responsibility model inherent in cloud deployments. This concept is a core component of certifications such as CompTIA Security+, CySA+, and the CISSP.
