"I previously worked for a fintech startup that provided investment research and recommendations to retail investors. As the security analyst for the company, I was responsible for the security of the company's network, which housed all of the billing and contact information for our subscribers. Well, several years in, our server was breached, and the hackers captured this sensitive subscriber information. Obviously, this had the potential to be devasting for the company in terms of its reputation, as well as financially. I jumped into action. First, I investigated how the breach had happened in the first place. In this case, it appeared that the hackers had exploited an outdated version of Windows that was still being used by one of the company's key tech employees. The attackers gained full control of his computer, which allowed them to install a keylogger and steal all of his passwords, including his SSH credentials. The lesson I learned from this was that I needed to create a structured process to ensure that all employees were continually updating the various programs on their computers, including their anti-virus software and operating system. I collaborated with management and other IT colleagues to communicate with subscribers and set up credit monitoring for them, in addition to examining and strengthening all of our security methods so this would never happen again. Let me tell you, this was a huge learning experience for me, and to this day, I never rest on my laurels when it comes to network security because I am well aware that hackers are always out there looking to take advantage in any way they can."
