Cybersecurity Measures for Financial Institutions

This case study outlines the cybersecurity measures implemented by a financial institution to enhance its security posture against potential intrusions and unauthorized access. The institution, which guarantees deposits and removes insolvent banks, faced significant risks due to its large data holdings and the ongoing threat environment. The IT department was tasked with reducing these risks, leading to the deployment of an AdminVM and two WorkerVMs across different hypervisor clusters. The deployment included creating a network of decoys that imitated Windows hosts and simulated user behavior, effectively generating around 10,000 file decoys. This strategy improved the detection of man-in-the-middle (MiTM) attacks by providing numerous false targets that blended seamlessly with real systems. Additionally, decoys imitating VMware ESXi and various web services were established, complicating the attacker's ability to navigate the infrastructure unnoticed. The case study emphasizes the effectiveness of these measures in enhancing the institution's cybersecurity framework.
