Apa itu ConfigServer Security & Firewall (csf)?
ConfigServer Security & Firewall (csf) adalah salah satu aplikasi Firewall untuk mengamankan Server Linux Anda yang sudah memiliki kemampuan Stateful Packet Inspection (SPI). SPI ini bertugas untuk memisahkan paket-paket data yang boleh masuk dengan paket data yang tidak boleh masuk kedalam server, seperti port mana saja yang akan dibuka dan ditutup, dari mana saja IP yang boleh mengakses server dan sebagainya, sehingga keamanan server linux akan tetap terjaga.

  18. Easy upgrade between versions from shell
  19. Pre-configured to work on a cPanel server with all the standard cPanel ports open
  20. Pre-configured to work on a DirectAdmin server with all the standard DirectAdmin ports open
  21. Auto-configures the SSH port if it's non-standard on installation
  22. Block traffic on unused server IP addresses - helps reduce the risk to your server
  23. Alert when end-user scripts sending excessive emails per hour - for identifying spamming scripts
  24. Suspicious process reporting - reports potential exploits running on the server
  25. Excessive user processes reporting
  26. Excessive user process usage reporting and optional termination
  27. Suspicious file reporting - reports potential exploit files in /tmp and similar directories
  28. Directory and file watching - reports if a watched directory or a file changes
  29. Block traffic on a variety of Block Lists including DShield Block List and Spamhaus DROP List
  30. BOGON packet protection
  31. Pre-configured settings for Low, Medium or High firewall security (cPanel servers only)

  35. Alert sent if server load average remains high for a specified length of time
  36. mod_security log reporting (if installed)
  37. Email relay tracking - tracks all email sent through the server and issues alerts for excessive usage (cPanel servers only)
