The escalation of insider threats poses significant harm to organizations and businesses, necessitating a thorough understanding of their nature and the associated threat landscape to develop effective Insider Threat Programs (ITP). This paper delves into the pervasive issue of insider threats within the retail industry, examining the applicability of the Cyber Kill Chain (CKC) to comprehend these threats. The retail sector, with its diverse and dispersed workforce, faces unique vulnerabilities that require organized strategies and proactive measures. By strategically integrating the CKC framework, the ITP systematically identifies and prevents insider threats at every stage of their lifecycle. This comprehensive approach serves as an indispensable element in fortifying the security framework of both the retail industry and broader economic landscape.
