The PsychologIcal Security System (P.I.S.S.) is the last barrier and desperate security system for the lazy trusted system administrator. It's based on a deep investigation process trying to find the most generalized psychological system intrusion profile. The protection scheme is included both in English and Spanish.
Firegate Server is a self-managing server operating system designed for small and mid-sized businesses. It securely connects offices to the Internet and to each other, protecting valuable electronic information. Office staff can surf the Web, send and receive email, host the company Web site, share files, host a customer database, and more. It is controlled through a simple Web browser or mobile telephone interface and managed by an artificial intelligence-based administration service.
rpfcd (Remote packet filter control daemon) allows remote control and monitoring of OpenBSD's packet filter. It communicates with clients using the RPFC protocol running on top of SSL. The protocol is designed to be relatively forgiving and easy to use. Its goal is to provide a common framework for pf control and monitoring. Instead of running pfctl/tcpdump/pflogd, writing ad-hoc parsing scripts, and sending the results by mail, rpfcd will provide the same and much more via a transparent server-client interface. Together with a decent CLI/GUI client, pf firewall monitoring becomes rather easy. This is especially interesting if you have several pf firewalls to control and monitor.
mfw allows multiple firewall configurations to be managed from the commandline on Mac OS X. Multiple firewall modes (and easy means of selecting between them) are useful on laptops, where one may want a default paranoid firewall, a mode for network scanning with nmap, modes for various networked games, or to run a software Network Address Translation (NAT) wireless base station.
trollhunter offers various tools to either analyze existing logfiles or monitor firewall activity in real time. Currently standard log messages generated by a Linux 2.4 kernel netfilter/iptables firewall are supported. You can choose from a Perl/Tk interface or run in commandline standard ASCII color TTY terminal.
connect-tunnel is a simple Perl script that lets you tunnel anything through a CONNECT-aware HTTP proxy. It supports multiple tunnels and multiple connections to those tunnels, and all of the authentication methods that libwww-perl supports (Basic, Digest, and NTLM). It works under Unix and Windows.
Extensible Messaging Platform is a spam-filtering firewall server application. It protects any SMTP mail server from spam, email- orne viruses (including dangerous auto-launch viruses) and other objectionable content. It filters mail using complex contextual signatures (not simple keyword lists). The use of contextual signatures results in high success and extremely low false-positive rates. Additional features include automatic XML extraction/database insertion, optional POP3 retrieval, comprehensive user-definable contextual filtering, content-based message routing and developer API.
