A case analysis of information systems and security incident responses

摘要

Our case analysis presents and identifies significant and systemic shortcomings of the incident response practices of an Australian financial organization. Organizational Incident Response Teams accumulate considerable experience in addressing information security failures and attacks. Their first-hand experiences provide organizations with a unique opportunity to draw security lessons and insights towards improving enterprise-wide security management processes. However, previous research shows a distinct lack of communication and collaboration between the functions of incident response and security management, suggesting organizations are not learning from their incident experiences. We subsequently propose a number of lessons learned and a novel security-learning model.
