LINUX (thanks to DogMeat): Quote from: DogMeat;160115Having used various distros of Linux/BSD over the years for firewalling and routing duties, recently I've been trying security/AV/router sentry systems.
The PC
All you need is an old PC and a couple of NICs - my current box has 128MB of memory and a 4GB HD. I'm sure most people's upgrades have left them with enough bits lying around to build one. With 3 NICs, you have the option to set up a DMZ - a network segment available on the Internet (web, mail ftp, etc.) but isolated from the rest of your home network - probably overkill for the average non-geek though...
The Distros
IPCop - http://www.ipcop.org (http://www.ipcop.org/)
"IPCop Linux is a complete Linux Distribution whose sole purpose is to protect the networks it is installed on. By implementing existing technology, outstanding new technology and secure programming practices IPCop is the Linux Distribution for those wanting to keep their computers/networks safe."
Endian Firewall Community Edition - http://www.endian.it/en/community
"Endian Firewall Community is a "turn-key" linux security distribution that turns every system into a full featured security appliance. The software has been designed with "usability in mind" and is very easy to install, use and manage, without losing its flexibility. The features include a stateful packet inspection firewall, application-level proxies for various protocols (HTTP, FTP, POP3, SMTP) with antivirus support, virus and spamfiltering for email traffic (POP and SMTP), content filtering of Web traffic and a "hassle free" VPN solution (based on OpenVPN). The main advantage of Endian Firewall is that it is a pure "Open Source" solution."
Smoothwall - http://www.smoothwall.org (http://www.smoothwall.org/)
"SmoothWall Express is an open source firewall distribution based on the GNU/Linux operating system. Linux is the ideal choice for security systems; it is well proven, secure, highly configurable and freely available as open source code. SmoothWall includes a hardened subset of the GNU/Linux operating system, so there is no separate OS to install. Designed for ease of use, SmoothWall is configured via a web-based GUI, and requires absolutely no knowledge of Linux to install or use."
RedWall - http://www.redwall-firewall.com (http://www.redwall-firewall.com/)
- Configuration is currenty stored on a floppy/USB Memory Stick/Harddrive or sent by email
- Most reporting functionality is done via mysql (except for the squid reports)
- based on gentoo
- bridging support
- Mail Virus scanning, spamfiltering and gateway functionality
- /etc is writable (tmpfs) feeded by the configuration medium
- /var is writable (ramdisk or harddisk) (you are not going to run squid on a ramdisk... aren't you ?)
- The cd will (at least it should) detect all your network cards during the initial boot"
m0n0wall - http://m0n0.ch/wall/
"m0n0wall is a project aimed at creating a complete, embedded firewall software package that, when used together with an embedded PC, provides all the important features of commercial firewall boxes (including ease of use) at a fraction of the price (free software).
m0n0wall is based on a bare-bones version of FreeBSD, along with a web server, PHP and a few other utilities. The entire system configuration is stored in one single XML text file to keep things transparent.
m0n0wall is probably the first UNIX system that has its boot-time configuration done with PHP, rather than the usual shell scripts, and that has the entire system configuration stored in XML format."
In Use
I've only used IPCop and Endian, which are both (loosely) branched from the original Smoothwall, but they are both easy to install and configure. Just make sure you have your network planned and written down before you start the setup. Both have the facility to make a backup of your working configuration, so if you decide to try something else, you can restore a working version back the way it was.
The facilities in each distro vary somewhat some will provide web content filtering, some will provide SPF and so on - visit the web sites for a detailed list.
Conclusion
With the exception of m0n0wall, all the distros offer AV and spam filtering, NAT, firewalling, DHCP and proxying services which essentially remove the need for running the same stuff on your windows box - if set up and maintained regularly. Of course, anything that takes the load off your games machine has got to be a bonus - so dig out that "obsolete" PC, set up a proper sentry system and wave goodbye to Norton bloatware and the like.:thumbsupsmileyanim:
