The Port Scan Attack Detector (psad) is a collection of three system daemons that are designed to work with the Linux iptables firewalling code to detect port scans and other suspect traffic. It features a set of highly configurable danger thresholds (with sensible defaults), verbose alert messages, email alerting, DShield reporting, and automatic blocking of offending IP addresses. Psad incorporates many of the packet signatures included in Snort to detect various kinds of suspicious scans, and implements the same passive OS fingerprinting algorithm used by p0f.

eurephia is an authentication plug-in for OpenVPN. It enhances the OpenVPN authentication process by using user name and password authentication in addition to SSL certificates. If too many failed attempts are registered, the user account and/or IP address will be blocked. For Linux servers, iptables support is also included, which can be used to restrict each user's network access through the VPN channel. OpenVPN 2.2 or later is required.
