Real-World Case Studies and Lessons Learned
Case studies provide valuable insights into how organizations have dealt with cybersecurity risks and the lessons they have learned. In this section, we will analyze several real-world examples of cyber incidents and the strategies that organizations implemented to manage and mitigate risks.
Case Study 1: Equifax Data Breach (2017):
The Equifax breach was one of the most significant cybersecurity events, impacting over 147 million people. The breach occurred due to the exploitation of an unpatched vulnerability in Apache Struts, a widely used web application framework. The case study will focus on risk identification and the failure to patch vulnerabilities in time. It will also discuss how Equifax’s response and communication strategies were criticized and the lessons learned about the importance of timely patch management and public communication during a breach.
Case Study 2: Target Data Breach (2013):
In this breach, attackers gained access to Target’s network through a third-party vendor, compromising 40 million credit and debit card accounts. The case will explore third-party risk management, emphasizing the importance of securing vendor relationships and monitoring their cybersecurity practices. It will also discuss Target’s response, how it addressed the breach, and the long-term effects on its brand reputation.
Case Study 3: WannaCry Ransomware Attack (2017):
The WannaCry ransomware attack affected hundreds of thousands of systems worldwide, exploiting a vulnerability in Microsoft Windows. The attack highlighted the risk of using unsupported software and the importance of regular patching. The case study will delve into the importance of proactive security measures, continuous monitoring, and the role of cybersecurity training for employees.
These case studies help learners understand the practical implications of cybersecurity risk management and provide concrete examples of the consequences of poor risk management.
