This abstract provides an in-depth examination of the security challenges in cloud computing, focusing on the fundamental principles of the CIA triad: Confidentiality, Integrity, and Availability. Cloud computing's widespread adoption, driven by its scalability and cost-effectiveness, has introduced new vulnerabilities due to its centralized data storage, shared resources, and remote access1. This document explores both current and future security challenges, dissecting key vulnerabilities and strategies for safeguarding data.
Data Integrity is defined as the accuracy, consistency, and reliability of data throughout its lifecycle2. Threats to integrity include unauthorized access, human error, and hardware failures3. The paper discusses management strategies such as data encryption, digital signatures, access control mechanisms, and continuous auditing4.
Data Availability is the ability for users to access their data without interruption5. Threats to availability include Distributed Denial of Service (DDoS) attacks, natural disasters, system failures, and resource drain666666666. To ensure high availability, the paper highlights the importance of load balancing, redundancy, disaster recovery plans, and Service Level Agreements (SLAs)777777777.
Data Confidentiality involves protecting sensitive data from unauthorized access8. Challenges include insider threats, shared resources in multi-tenant architectures, and vulnerable APIs999999999. The document outlines key measures like data encryption, Multi-Factor Authentication (MFA), secure APIs, and network segmentation10101010101010101010101010101010. It also touches on advanced techniques like the zero-trust security model, homomorphic encryption, and Secure Access Service Edge (SASE) frameworks111111111111111111.
The paper concludes by emphasizing the intricate interrelation of the CIA triad, noting that a failure in one area can lead to broader security issues12. The success of cloud computing relies on proactive, layered, and adaptive security models13. This forward-looking perspective lays the foundation for future research and development to promote resilience against dynamic cloud threats14.
