Cloud security in practice: A technical guide to confidentiality, integrity, and availability at scale

Cloud computing has revolutionized how businesses deploy and scale IT infrastructure. However, this shift introduces significant security challenges that require well-architected security techniques across the cloud ecosystem. This paper presents comprehensive techniques to ensure confidentiality, integrity, and availability of data and systems in cloud environments. Covered topics include data encryption, secure storage, key management, logging and monitoring, virtual private cloud (VPC) security, container security, DAST and SAST scanning, baseline imaging, configuration management, and change control practices. These are mapped to CSA's Cloud Controls Matrix (CCM) and CAIQ v4.0 domains to demonstrate holistic cloud risk management. Real-world examples, missteps, and best practices are discussed
