An Emerging Technologies in Cloud Security

Cloud computing continues to evolve rapidly, and so do the security technologies designed to protect data, workloads, and access in cloud environments. This paper surveys the most influential emerging technologies shaping cloud security today: confidential computing, Secure Access Service Edge (SASE), Cloud Native Application Protection Platforms (CNAPP), AI/ML–driven threat detection and response, homomorphic encryption and secure multi-party computation, post-quantum cryptography, server less & runtime protection, and privacy-preserving analytics (including federated learning). For each technology we describe the underlying principles, current cloud-provider and industry implementations, security benefits, practical limitations, and open research problems. The paper concludes with recommendations for practitioners and a roadmap for future academic work. Key claims about standards adoption and provider initiatives are supported with recent sources.
