University Health Network Ransomware Attack Prevention Case Study

This case study details the cybersecurity measures implemented by the University Health Network (UHN) to enhance visibility and prevent ransomware attacks. The document outlines the challenges faced by UHN, particularly in gaining East-West visibility within a resource-constrained public sector environment. It describes the solutions adopted, including the GigaVUE HC and TA Series, which facilitate improved traffic visibility and support the integration of various security tools without affecting network performance. The case study highlights the effectiveness of these tools in identifying potential ransomware attacks, with specific incidents documented where threats were caught within an hour, preventing significant damage. Additionally, it discusses the benefits of using Gigamon, such as extending the life of existing hardware and simplifying the pilot process for new security tools. The document emphasizes the importance of visibility in cybersecurity and outlines future plans for utilizing SSL decryption features to further enhance security measures.
