Cloud Security encompasses the strategies, technologies, and best practices used to protect data, applications, and infrastructure hosted in cloud environments such as AWS, Azure, and Google Cloud. It addresses unique challenges like shared responsibility, dynamic scaling, and multi-tenancy by implementing robust access controls, encryption, monitoring, and compliance measures. Cloud security solutions help organizations detect and mitigate threats, prevent unauthorized access, and ensure the confidentiality, integrity, and availability of cloud-based resources. As businesses increasingly rely on cloud services, maintaining strong cloud security is essential for operational resilience and regulatory compliance.
