The rapidly evolving cyber threat landscape has necessitated the development of sophisticated frameworks and methodologies to protect organizational information assets. This research explores integrative approaches to cyber threat intelligence (CTI) and intrusion analysis, emphasizing the functional deployment of cybersecurity situation centers, the diamond model of intrusion analysis, and the cyber kill chain framework. The study synthesizes contemporary literature and empirical insights to provide a comprehensive understanding of how intelligence-driven strategies enhance organizational cybersecurity resilience. A detailed examination of threat intelligence gathering, contextualization, and application is conducted, highlighting cognitive, technical, and operational considerations in detecting, analyzing, and mitigating cyber attacks. Furthermore, the research explores unified approaches to kill chain modeling, emphasizing how such integration can inform real-time threat detection, prioritization, and response. The findings underscore the importance of combining structured analytical models with dynamic, context-aware intelligence to counter increasingly sophisticated cyber adversaries. The study concludes with recommendations for operationalizing these frameworks in organizational contexts, highlighting limitations and future research directions for enhancing proactive cybersecurity postures.
