One of the more popular firewall products for the small business market is the Cisco PIX 501. Out of the box it requires just a few configuration entries and you are up and running.
In this guide, we will walk through the steps for configuring your brand new pix at the network edge.
This guide is written for the user who has no knowledge of the PIX firewall. As such, it is not a treatise on network security, but a quick, by-the numbers guide to configuring a PIX firewall with as little jargon as possible.
We are assuming that you have an internet connection with at least one static IP address. While the PIX can easily handle a dynamic IP address (that is the default configuration), you won't be able to easily configure remote access, VPNs, Mail, or web servers without a static IP address.

Electronic Data for Maximum Backup Efficiency
Most companies today, whether large or small, are experiencing data overload. According to industry studies, many organizations are finding that they have to double their storage capacities every six to 12 months. With recent regulations such as Sarbanes-Oxley, HIPAA and others requiring businesses to accurately record and report and thus generate more data, this explosion of data will not subside anytime soon. In fact, as additional regulations are being anticipated for banking and other industries it is likely to continue it's rapid increase.

What is called Wardriving And How To Prevent It
Imagine a car equipped with nothing more than a laptop computer, a portable GPS receiver, and a wireless network card slowly strolls through your neighborhood. Unknown to any onlookers, this is no ordinary vehicle; rather, it is a wardriving machine. As the car strolls past homes and businesses, a wireless network card (available at any electronics store for as low as $25) scans for any wireless access points. Anyone with a wireless network (and there are many out there) is vulnerable. The computer is looking for what is called an SSID. An SSID is your wireless network name and it is being constantly transmitted by your access point, letting computers know of its presence. The wardriver uses software such as Netstumbler (for windows) or Cismet (for linux) to scan the airwaves for SSIDs. The program can track various access points at once and monitor the signal strength. These programs can also check to see if the network is encrypted. The wardriver will generally configure his or her software to log any strong unencrypted signals. Using the GPS receiver, the coordinates of the strong signal will be recorded. After this preliminary drive, the wardriver can return to the locations that were recorded, and connect to the access point. Once connected to an unencrypted network, the wardriver can use the victim's internet access, and can also explore computers on the network. If files are being shared within someone's private network, all of that information is susceptible to a wardriver. Furthermore, once in the network,

How to Make Wireless secure?
It's common nowadays to see people sitting in a park and computing, or at their local Starbucks, tapping away on their keyboards. At home, people are taking advantage of the freedom from cables and wires that a wireless network brings.
But along with that freedom come dangers. After all, wireless is really just radio waves, which don't just go between your laptop and your network, they go all over the place, just waiting to be plucked from the ether by someone with just the right device and bad intentions.
This Special Report covers home users. Small Businesses face increased risks that come with an increased number of users with increased access to the businesses' hardware.
