A Comprehensive Study on Data Storage Security Issues and Services in Cloud Computing

Abstract: Cloud computing has become an important platform for storing and managing data due to its scalability, flexibility, and cost effectiveness. However, outsourcing data to third-party cloud service providers introduces several security concerns, particularly related to confidentiality, integrity, and availability. This paper presents a study of data storage security issues in cloud computing and discusses cloud service models and deployment models from a storage perspective. It reviews existing security techniques such as encryption, identity-based authentication, and third-party auditing for ensuring data protection. The paper also examines major challenges including data privacy, data recoverability, media sanitization, insecure APIs, vendor lock-in, and network dependency. The study highlights the need for effective security mechanisms to improve trust and reliability in cloud storage environments.
