In order to host this website I used my VPS I own on <a href="https://www.ionos.de/">IONOS</a>. As someone who has spent a lot of time in the Cybersecurity world, I gave my best to secure the VPS as well as possible. Login via SSH is enabled only via Private/Public Key Authentification and <a href="https://github.com/fail2ban/fail2ban">Fail2Ban</a> is setup to ban anyone who tries to login more than 5 Times. Once this was setup I created a way to &ldquo;pull&rdquo; the logs from nginx and fail2ban onto my private ProxMox server and Process these into Grafana. As I was doing this, I noticed that the fail2ban logfile has over 31.000 rows. Nothing suspicious for a public IP Address, yet a interesting amount of data.</p> <p>After getting my hands on these files I decided that I will try to parse and analyse these bruteforce attacks. Furthermore this will be written in go, because I am trying to hone my skills in it and it allows us to write extremely efficient, fast and lightweight code.</p>
