Abstract
Cloud computing has emerged as a transformative technology that enables on-demand access to shared computing resources, including networks, servers, storage, applications, and services. By shifting data storage and processing responsibilities from local machines to remote cloud infrastructures, organizations can reduce capital expenditure, improve scalability, and enhance operational efficiency. Cloud services are typically delivered through three primary modelsInfrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)and deployed using private, public, hybrid, or community clouds. However, the rapid adoption of cloud computing introduces significant security challenges related to data protection, privacy, trust, compliance, and system vulnerabilities. Ensuring secure cloud environments requires robust security policies, cryptographic algorithms, and threat-mitigation strategies. Various encryption techniques, such as symmetric-key ciphers (DES, AES, Blowfish), asymmetric-key algorithms (RSA, DiffieHellman), and hashing methods (SHA, MD5), play a crucial role in safeguarding data stored in or transmitted through the cloud. Despite advancements, issues such as privileged access, data segregation, DDoS attacks, and inadequate recovery mechanisms remain critical concerns. This paper provides an overview of cloud computing concepts, service models, security architectures, cryptographic algorithms, and existing threats, highlighting the need for comprehensive security frameworks to enhance trust and encourage broader adoption of cloud technologies.
