Hardening a Server in Two Steps: Fail2ban for the Host, SafeLine for the App

说明与用途

服务器通过 Fail2ban 和 SafeLine 保护免受 SSH 暴力破解和 Web 攻击。

问题

Attackers target both the host (SSH brute force) and the web application (SQLi, XSS, bots).

结果

The server is hardened against SSH brute force and web application attacks with minimal configuration.

工作流

• Install Fail2ban via package manager and enable service
• Verify sshd jail is active
• Install SafeLine WAF using provided script
• Configure SafeLine to proxy traffic to the web app
• Test a malicious payload to confirm it is blocked
• Review logs for bans and blocks

证据

Fail2ban watches your service logs and bans IPs that show hostile behavior — most usefully, repeated failed SSH logins.

来源

SafeLine is a self-hosted WAF that runs as a reverse proxy and inspects every HTTP request.
