Abstract The pervasive integration of information technology (IT) into the fabric of modern society, from critical national infrastructure to personal consumer devices, has created an expanded and complex digital landscape. This digital transformation, while driving unprecedented innovation and efficiency, has concurrently introduced a sophisticated and evolving array of cyber security threats. This research article provides a comprehensive analysis of the contemporary cyber security threat landscape and evaluates the corresponding frameworks for risk management within modern IT environments. The study begins with an examination of the evolution of threats, moving from simple malware to advanced persistent threats (APTs), ransomware-as-a-service (RaaS), supply chain attacks, and the emerging risks associated with artificial intelligence (AI) and the Internet of Things (IoT). Through a systematic literature review, this paper synthesizes existing academic and industry knowledge on threat vectors, vulnerability management, and the principles of risk assessment. The methodology section outlines a qualitative approach, leveraging case study analysis of major security incidents and a critical review of established risk management frameworks, including the NIST Cybersecurity Framework (CSF) and ISO/IEC 27001. The results and discussion section presents key findings, highlighting a significant gap between the rapid proliferation of threats and the often-siloed, reactive nature of traditional risk management practices. It argues for a paradigm shift towards a proactive, continuous, and integrated risk management strategy that embeds security into the DevOps lifecycle (DevSecOps) and leverages predictive analytics. The article concludes that effective cyber security in the modern era is not merely a technical challenge but a fundamental business risk that requires strategic alignment, continuous adaptation, and a culture of shared responsibility to ensure organizational resilience.
