  "account": "In this project, I aimed to enhance the security of an existing Ubuntu server by incorporating three security tools and observing their interactions. The first tool, UFW (Uncomplicated Firewall), was configured to regulate incoming network traffic and block unwanted connections. I allowed SSH traffic while blocking port 8088, verifying its effectiveness using Nmap scans and firewall logs. The second tool, Fail2Ban, was installed to automatically ban IP addresses after repeated failed SSH login attempts, which was tested by attempting multiple incorrect logins from Kali Linux. Finally, Logwatch was added to organize system logs into readable reports, making it simpler to review suspicious activity. Throughout the project, I tested each tool's interaction with the existing environment, learning that different security tools respond to various threats and that multiple tests are necessary to accurately evaluate their effectiveness.",
