Enhancing Cloud Security: A Comprehensive Framework for Real-Time Detection, Analysis and Cyber Threat Intelligence Sharing

Abstract

Cloud computing has emerged as a pivotal component of contemporary IT systems, affording organizations the agility and scalability required to meet the ever-changing demands of business. However, this technological evolution has introduced a new era of cybersecurity challenges, as attackers employ increasingly sophisticated strategies to breach cloud networks. Such breaches can have far-reaching consequences, including data loss, financial repercussions, reputational damage, and legal liabilities. In response to these challenges, developing a robust security framework is imperative for effectively safeguarding cloud infrastructure. This paper proposes a novel Hypervisor-based Virtual Machine Introspection (HVMI) for real-time detection and runtime forensic analysis of cyberattacks targeting cloud platforms. The framework proposed comprises several essential components, including a forensic application empowered by Virtual Machine Introspection (VMI) for real-time memory analysis, a centralized Cloud Forensic Tool (CFT) portal for streamlined incident management, and a data transmission and integration web service. Notably, this framework is founded upon a commitment to continuous optimization and enhancement. This iterative process is facilitated through a collaboration approach. It involves fine-tuning various aspects of the framework, such as adjusting settings for VMI, refining criteria for classifying incidents, and updating security controls. Enhancing the forensic application represents a proactive measure aimed at improving the efficiency and effectiveness of VMI and forensic analysis capabilities. The iterative refinement process integrates incident analysis, threat intelligence infusion, and collaborative efforts to adapt to emerging challenges. This dynamic approach fosters a flexible security posture capable of detecting, analyzing, and responding to emerging attacks within cloud platforms. In summary, the proposed framework embodies a comprehensive approach to cloud security, integrating advanced technology with continuous refinement to protect cloud infrastructure, mitigate risks, and navigate the everevolving cybersecurity threat landscape effectively.
