psad 2.4.5

psad is an intrusion detection system built around iptables log messages to detect, alert, and (optionally) block port scans and other suspect traffic. For TCP scans psad analyzes TCP flags to determine the scan type (syn, fin, xmas, etc.) and corresponding command line options that could be supplied to nmap to generate such a scan. In addition, psad makes use of many TCP, UDP, and ICMP signatures contained within the Snort intrusion detection system (see http://www.snort.org/) to detect suspi

Dowse 0.9

Dowse is a transparent proxy facilitating the awareness of ingoing and outgoing connections, from, to, and within a local area network. Dowse provides a central point of soft control for all local traffic: from ARP traffic (layer 2) to TCP/IP (layers 3 and 4) as well as application space, by chaining a firewall setup to a trasparent proxy setup. A core feature for Dowse is that of hiding all the complexity of such a setup.

IPTables::Parse 1.6

The IPTables::Parse package provides an interface to parse iptables or ip6tables rules on Linux systems through the direct execution of iptables/ip6tables commands, or from parsing a file that contains an iptables/ip6tables policy listing. Note that the 'firewalld' infrastructure on Fedora21 is also supported through execution of the 'firewall-cmd' binary. By default, the path to iptables is assumed to be '/sbin/iptables', but if the firewall is 'firewalld', then the '/usr/bin/firewall-cmd' is u
