(* may require custom regex patterns for some functions)

Supported and Tested Virtual Servers

**Virtuozzo **OpenVZ

VMware UML

Xen MS Virtual Server

(** requires correct iptables configuration on host server)

This suite of scripts provides:

Straight-forward SPI iptables firewall script

Daemon process that checks for login authentication failures for:

Courier imap, Dovecot, uw-imap, Kerio

openSSH

cPanel, WHM, Webmail (cPanel servers only)

Pure-ftpd, vsftpd, Proftpd

Password protected web pages (htpasswd)

Mod_security failures (v1 and v2)

Suhosin failures

Exim SMTP AUTH

Custom login failures with separate log file and regular expression matching

POP3/IMAP login tracking to enforce logins per hour

SSH login notification

SU login notification

Excessive connection blocking

UI Integration for cPanel, DirectAdmin and Webmin

Easy upgrade between versions from within cPanel/WHM, DirectAdmin or Webmin

Easy upgrade between versions from shell

Pre-configured to work on a cPanel server with all the standard cPanel ports open

Pre-configured to work on a DirectAdmin server with all the standard DirectAdmin ports open

Auto-configures the SSH port if it's non-standard on installation

Block traffic on unused server IP addresses - helps reduce the risk to your server

Alert when end-user scripts sending excessive emails per hour - for identifying spamming scripts

Suspicious process reporting - reports potential exploits running on the server

Excessive user processes reporting

Excessive user process usage reporting and optional termination

Suspicious file reporting - reports potential exploit files in /tmp and similar directories

Directory and file watching - reports if a watched directory or a file changes

Block traffic on the DShield Block List and the Spamhaus DROP List

BOGON packet protection

Pre-configured settings for Low, Medium or High firewall security (cPanel servers only)

Works with multiple ethernet devices

Server Security Check - Performs a basic security and settings check on the server (via cPanel/DirectAdmin/Webmin UI)

Allow Dynamic DNS IP addresses - always allow your IP address even if it changes whenever you connect to the internet

Alert sent if server load average remains high for a specified length of time

mod_security log reporting (if installed)

Email relay tracking - tracks all email sent through the server and issues alerts for excessive usage (cPanel servers only)

IDS (Intrusion Detection System) - the last line of detection alerts you to changes to system and application binaries

SYN Flood protection

Ping of death protection

Port Scan tracking and blocking

Permanent and Temporary (with TTL) IP blocking

Exploit checks

Account modification tracking - sends alerts if an account entry is modified, e.g. if the password is changed or the login shell

Shared syslog aware

Messenger Service - Allows you to redirect connection requests from blocked IP addresses to preconfigured text and html pages to inform the visitor that they have been blocked in the firewall. This can be particularly useful for those with a large user base and help process support requests more efficiently

Country Code blocking - Allows you to deny or allow access by ISO Country Code

Port Flooding Detection - Per IP, per Port connection flooding detection and mitigation to help block DOS attacks

DirectAdmin UI integration

Updated Webmin UI integration

WHM root access notification (cPanel servers only)

New in v5: lfd Clustering - allows IP address blocks to be automatically propagated around a group of servers running lfd. It allows allows cluster-wide allows, removals and configuration changes

New in v5: Quick start csf - deferred startup by lfd for servers with large block and/or allow lists

New in v5: Distributed Login Failure Attack detection

New in v5: Temporary IP allows (with TTL)

New in v5: IPv6 Support with ip6tables

New in v5: Integrated UI - no need for a separate Control Panel or Apache to use the csf configuration

New in v5: Integrated support for cse within the Integrated UI

New in v5: cPanel Reseller access to per reseller configurable options Unblock, Deny, Allow and Search IP address blocks

...lots more!

The reason we have developed this suite is that we have found over the years of providing server services that many of the tools available for the task are either over-complex, not user friendly, or simply aren't as effective as they could be.
