SECURITY APPROACHES AND CHALLENGES IN CLOUD COMPUTING

encryption, privacy and access control

Abstract

This work investigates the approaches and challenges of security in cloud computing, with emphasis on cryptography, privacy, and access control. Firstly, the importance of cloud security and the main risks faced by users and service providers are explored. Next, cryptographic techniques used to protect data in transit and at rest are discussed, as well as the challenges associated with their implementation. Additionally, privacy issues related to data collection, storage, and processing in the cloud, including regulations and standards for sensitive data against unauthorized access, are addressed. It is concluded by highlighting the importance of integrated security approaches and suggesting areas for future research to enhance cloud computing security. Among the works that guide the analysis are “O Escudo da Privacidade na Era da Conectividade” (2023), by Juliane Ferreira, “What is identity and access management?” by Matthew Kosinski e Amber Forrest (2024) e “A survey on security issues in service delivery models of cloud computing” (2010), de S. Subashini and V. Kavitha.
