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.

FreeBSD® is an advanced operating system for modern server, desktop, and embedded computer platforms. FreeBSD's code base has undergone over thirty years of continuous development, improvement, and optimization. It is developed and maintained by a large team of individuals. FreeBSD provides advanced networking, impressive security features, and world class performance and is used by some of the world's busiest web sites and most pervasive embedded networking and storage devices.

VMware software provides a completely virtualized set of hardware to the guest operating system.VMware software virtualizes the hardware for a video adapter, a network adapter, and hard disk adapters. The host provides pass-through drivers for guest USB, serial, and parallel devices. In this way, VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest. In practice, a system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer, and there resume execution exactly at the point of suspension. Alternately, for enterprise servers, a feature called VMotion allows the migration of operational guest virtual machines between similar but separate hardware hosts sharing the same storage. Each of these transitions is completely transparent to any users on the virtual machine at the time it is being migrated.

Microsoft's flagship product is the Windows operating system. It has been produced in many versions, including Windows 3.1, Windows 95, Windows 98, Windows 2000, Windows Me, Windows Server 2003, Windows XP, Windows Vista, Windows Server 2008 and Windows 7. Almost all IBM compatible personal computers come with Windows preinstalled. The current desktop version of Windows is Windows 7.

ZABBIX is a network management system application. It is designed to monitor and track the status of various network services, servers, and other network hardware. ZABBIX offers several monitoring options. Simple checks can verify the availability and responsiveness of standard services such as SMTP or HTTP without installing any software on the monitored host. A ZABBIX agent can also be installed on UNIX and Windows hosts to monitor statistics such as CPU load, network utilization, disk space, etc. ZABBIX supports a variety of real-time notification mechanisms.

InfoSec (Information Security) is the ongoing process of exercising due care and due diligence to protect information, and information systems, from unauthorized access, use, disclosure, destruction, modification, or disruption or distribution. The never ending process of information security involves ongoing training, assessment, protection, monitoring & detection, incident response & repair, documentation, and review.

Perimeter

The Perimeter is the point at which your company's Network connects with the Internet. It usually consists of your Internet Service Provider's (ISP) router, Firewalls, Intrusion Protection/Detection Servers and Proxy Servers.

Your ISP's router is the device that provides internet access to the location you do business in. Whether you have a T1, Cable or DSL, chances are that you have some sort of device that connects you directly to the Internet via your ISP. You don't have much control over this device. Control of it belongs to your ISP, so the focus really begins with your Firewall.

Your Firewall is where you gain control over your Internet connection. This device allows you to control what comes into your Network and what does not. It also allows you to control what flows out of your network and what does not. This is the most important part of your network. Operating without a robust Firewall is similar to leaving the front door to your business unlocked and wide open.

Intrusion Detection/Prevention Servers (IDS/IPS) offer detection and prevent of malicious activity on your Network that did not come through the Firewall. An example of this can include a laptop that may have picked up a virus on a different network that yours. Once that laptop connects to your network, the virus can permeate the Network from the inside out. An IDS/IPS implementation detect and prevent this virus from spreading to other devices on your Network.

A Proxy Server allows you to control where your users visit on the Internet. This can protect you by not allowing your users to visit web sites that are known to house malware infected downloads. It also allows you to enhance productivity by only allowing your users to visit work related web content.
