Here is the conclusion to Sam's "Mother Law" tips on securing your wireless network.
1. Don't broadcast your SSID
Most Wireless AP (access points) and routers have an auto setting of broadcasting the default network’s name or what is called the SSID (Service Set Identifier). This type of setup makes it completely easy for wireless clients to connect to your network since they can see it visible through their wireless client application. Turning off SSID broadcast for your network makes it invisible to your neighbors and passers-by (though it will still be detectible by WLAN "sniffers"). That is why it’s important to have complete security through WEP/WPA encryption which is mentioned as the next step in ensuring a secured wireless network.
2. Use WPA encryption
The 802.11 standard, WEP (Wired Equivalency Privacy) encryption, has been known for its weaknesses and makes it easy for a very determined user with the right applications and equipment to crack/break encryption of a wireless network and obtain confidential data housed in servers/workstations. A more effective method of encryption is to use WPA (Wi-Fi Protected Access), a protocol that was introduced to protect wireless networks with the use of a passphrase. The client end application feature such as Windows XP (Service Pack 2) and Windows Vista have WPA accessibility incorporated in their product. Our organization is a Microsoft Gold Certified Partner who will ensure that integration meets the up most Microsoft standards.

Don't you love wireless? In the past few years, wireless accessibility is becoming less a luxury, and more a necessity in many homes, offices, and retail stores. This is partly due to wireless networking products and solutions becoming much more affordable in price. However, wireless products are still advanced in operation and it takes trained professionals to understand what solutions and products are needed to run a wireless network with performance, security, and reliability.
Because so many of our clients deal with wireless issues, we developed a "Mother Law" on wireless. This is part one of three methods to ensure your WLAN is secure:
1. Secure your wireless router or access point administration interface
All routers and AP have an administrator password needed to log so you can modify settings. Most devices have a very weak default password like “admin and password” or even the manufacturers name. As soon as you set up a WLAN this is the first thing you will need to change. This ensures external threats are not able to login to the device and make adjustments, which can lead to hacks. Make sure you write down this information and keep in a very safe place. For Mother clients, we store recorded data in very tight secured measures to ensure our clients' networks are totally safe. It's very important you (or an outsourced IT company like Mother) know your settings and passwords for your wireless interface. This information is extremely important. However, we often find new clients have no documentation on their wireless networking. This can cause countless headaches and expenses trying to dig up this information. With Mother, our clients don't even have to think about it. They know their data is documented AND secure.
Stay tuned for the last two tips in part two!

Imagine if when you got the work, the lights wouldn’t go on. Or if, during the day, the power would periodically go out. Or just the power failed to your printer, or in your office, or the phone system, or – God forbid – the coffee maker! What would that be like? What would your reaction be? My guess is you wouldn't be happy.
So why do so many business owners accept this behavior when it comes to their computer networks? I suspect it comes from the ill-informed comments from many substandard IT novice support folks - this is the normal way IT works. “Its just the nature of the beast!”
Well, it’s just not so! Yes, computer networks are very complex, evolving systems requiring frequent attention. But no one should accept substandard performance from such an important asset in our businesses – least of all small and mid-sized businesses who can least afford the costs and interruptions of flaky systems.
At Mother, we think your IT systems should work more like that light switch – flip it and the lights go on. Don't think about how it works, just assume it will. Become so used to the high level of service resulting in the consistent performance that all you do is flip the switch.
Think about IT systems the same way. You shouldn’t have to worry about the complexity of all those computers and software and network switches you need to run your business. You should be free to focus on your business – adding value to your customers.
Let Mother make those systems work like the light switch. But please, don’t flip us off.

As Mother's resident marketing go to gal, I represent average people. People who don't know more about their computers than how to turn it on, open Outlook, and possibly (on a good day) download a new font. I'm the person who always starts my help desk calls with, "okay, I have no idea what I did, but..." I'm the person who is intimidated by the computer salesman at Best Buy, much less expertly trained IT professionals like the ones we have at Mother. And like all normal people, I have a very consistent stereotype of who IT people are. I'm betting you have the same one I did.
At least when it comes to our IT guys, many of my assumptions have changed. They're not like all the help desk people I've talked to on the phone over the years. They're not like nerds on TV. They're, well, different.
At Mother, our IT professionals are friendly. Nice. Polite. They even (gasp) speak in terms you can understand. Whether it is the help desk pro you get on the phone when you have no idea what happened or the engineer who helps innovate ways to increase efficiencies, they are wonderful people who treat you with respect. They get that you just want to do your job, whatever it is. They want to help you and to make things better and to stop problems from happening. They care about your IT security, and even though we're an outsourced IT company, they work for your best interests. They're not nerds or geeks - they're advocates for your company and for who your company will be.
Take it from an average person like me. You want exceptional people like the guys I work with working with you too.

I've noticed people often have difficulty knowing how to delete and remove certain email, calendar, contacts, etc. settings from their windows mobile phone, once it is configured to the exchange server. But the solution is pretty easy. Just follow the steps below.
In order to remove old configuration settings in a windows mobile phone:
-
On a windows mobile phone go to “START.”
-
Select “ActiveSync.”
-
Select “Menu.”
-
Select “Options.”
-
Go down to Email, Calendar, Contacts, and Tasks and uncheck the boxes.
-
Once you have unchecked boxes click OK (it will warn you that it will remove all the settings).
-
Now you are ready to go back and enter a new email exchange settings in your phone.
How to configure your phone to your email:
-
Go to START on windows mobile phone.
-
Select ActiveSync.
-
Select Menu.
-
Select Add Server source.
-
Enter your server address (i.e. mail.DomainName.com)
-
Now either check or uncheck the SSL check box . *(The SSL stands for Secure Sockets Layer. It is used to encrypt data sent from and to the server. To find out if SSL is being used on your network call your IT administrator.)
-
Enter your network username (i.e. jsmith)
-
Enter your network password
-
Enter your domain name (i.e. DomainName.com)
-
Select Next then Finish. The phone should start syncing your email to the phone.

David B.'s Tip: Securing Wireless Connection |

When you're in the office you assume your internet connection is secure. If you have a good IT services company (like Mother), you probably assume correctly. But how good is your network protection when you go home? Is your wireless connection secure then?
Here are a few ways to secure your wireless connection and some additional techniques to strengthen the security of your connection.
-
Supply a password/network key using Wired Equivalent Privacy Protocol (WEP) or Wi-Fi Protected Access (WPA) to allow users access to your wireless connection. This will help prevent unauthorized users from accessing your wireless connection.
-
After creating the WEP or WPA key, you can disable the broadcasting of your Security Set Identifier (SSID). This will disable the ability of outside users to detect the name of your wireless network.
-
Another technique is to enable Media Access Control (MAC) filtering. This will allow you to control which computers have authorization to use your wireless connection using the hardware address of the computers Network Interface Card (NIC).
-
Last but not least when you are not using you wireless connection turn off or unplug the wireless device.
