Security Challenges and Mitigation Strategies in Cloud Computing Environments

Abstract

Cloud computing has emerged as a fundamental paradigm shift in information technology, enabling
organizations to access scalable, on-demand computing resources over the internet. Despite its numerous
advantages, cloud computing introduces significant security challenges that threaten data confidentiality,
integrity, and availability. This paper provides a comprehensive review of the major security threats prevalent
in cloud environments, including data breaches, insider threats, insecure interfaces, account hijacking, and
denial-of-service attacks. We examine existing mitigation strategies such as encryption mechanisms, identity
and access management frameworks, intrusion detection systems, and multi-factor authentication protocols.
Additionally, this paper proposes an integrated security framework that combines proactive threat monitoring
with automated incident response to enhance the overall security posture of cloud deployments. The findings
suggest that a layered security approach, combining technical controls with organizational policies,
significantly reduces vulnerability exposure in cloud infrastructures
