READ THIS WRITEUP

In this GHW Init challenge, I learned all about cybersecurity. It was such an eye-opening experience, and I realized how vulnerable my application really was. That's why I made 2 big changes to my application:

  • Instead of storing the files on an unsafe server, I immediately sent the data to Hedera, without creating any temporary file on the disk.
  • I switched the server to run on a Rasberry Pi so that everything would be offline. This gave me a sense of safety because I managed the whole physical server.
