Internet Backup

Years ago, when the Internet was in its early stages and High Speed was the “New” thing many of us relied on a “dial-up” connection for backup. And as HS became more stable and the need for dial-up lessened we dropped our dial-up lines and thus our backup. Not really a good thing, however, today’s network would barely survive if we had to use a dial-up connection. Mainly it doesn’t support a fast enough bandwidth to support today’s internet needs. However, as the HS race continues, we are faced with troubling times when there is an outage. And often, the outage has nothing to do with us, or even our Local ISP from which we get our service. Internet traffic flows along the www highway between many nodes. If some some reason, one of those nodes goes down. So might our traffic. And if the node is close enough, it might bring out entire internet down. Now, this may be infrequent, but, should it happen can you survive without, and for how long. If this is a concern for you, then you need to employ failover technology to your network. Usually, this requires theĀ  need for specific failover routers which allow the connection of multiple internet providers. Obviously, this would require two ISP accounts and thus a costly one, but, how much is lost if you go down. Some of today’s devices also allow for the use of Wireless Aircards (cell phone carriers) for the failover or backup.

If downtime is a concern, or already a problem, don’t wait til it happens again.

Why VPN

Because, what was safe a year or so ago is no longer safe. Many of us relied on remote access programs such as PC Anywhere, Remote Admin and even Remote Desktop to connect to our computers while on the road. However, unless we have a strong username, and an even stronger password it might not be enough as the hackers know all the tricks and looking for the easy ins.

Having a VPN, usually proprietary to the MFG, coupled with strong UN/PW provides a much greater firewall against the ‘hacker’. A VPN connection not only requires a VPN sharedkey password, it requires the users UN & PW. However, the drawback to that is if your computer or laptop is stolen, then it becomes imperative to change the Shared Key immediately. The VPN also provides encryption of the data through the tunnel so if by some means the stream of data is compromised, your data is fully encrypted.

Another form of VPN, which eliminates the need for a VPN client being installed on a desktop or laptop is the SSL VPN. The SSL, short for Secure Socket Layer, is the same protection that is utilized in e-commerce and financial transactions on the web. As you hopefully know, https (vs http) is what you see (URL) when on an SSL connection. Basically it means that a secure connection (Shared Key) has been made and all traffic is encrypted. An SSL VPN connection allows the client to use any computer with web access (Internet Browser) to make a VPN connection via SSL.

Another advantage of either VPN method, is that it allow you to further secure your firewall by sealing an open port. And the less ports open, the better your odds of someone hacking in.

Say it Once, Say it a Million Times

The other day I had a referral call as they were having issues with their network and needed some quick help. Within just a few minutes of surveying their network I had my answer. I didn’t know what the problem was, or how bad it was, but I was quite sure I knew why. And it is probably one of the biggest, and equally, one of the most common problems out there.
The old adage, that the strongest chain is only as strong at it weakest link. Well, utilizing a ‘consumer’ grade router for a network and then having the wireless setup so that employees/customers can get online is a DISASTER just waiting to happen. And so it did for this client and so many others. Just cause it works at home or a friends, is by no means reason to trust it for protecting your business. Most of the time when I explain that in this scenario that any wireless user has access to your entire network they look bewildered. — Well, what else would you expect! And if you are saying “I have a password”, just as my new client stated, wake up! Think about it, now your patients, clients, employees or any of their friends now have it too. And betting bottom to dollar, it will be one of them that hacks you. Scary huh!
If you must rely on ‘consumer’ grade routers or products for your firewall protection. Then additional hardware, configuration and setup is 100% necessary if you also want to provide secure wireless. Even if it is for your employees! An unhappy employee is just as likely to give you something to remember as is your run of the mill hacker.
Your data and your network are your livelihood. Is it worth the risk. And sadly, this won’t be the last time I see it happen. No matter how many times I say it!

Just Love It

About a month ago I dropped my cell phone while running and it broke — so I was now forced to get a new phone. I had test drove the Sprint Instinct when it hit the market and returned it. Even with all it great features, it did less of what I wanted then my flip phone. But, now I had no choice and settled the HTC Hero. Can’t say I truly love it, as it has some serious issues. But, it get’s the job done. Yes, there are some cool apps, but about the only plus it has over the old phone is the ability of getting and viewing my emails. However, that is not the purpose of this post.
I had also recently purchased a Netbook, for portability. As for workability (actually doing work on them), they are pretty bad. Any who, the introduction of this device created a new problem in that it does not have a slot for my wireless air card – not good.
Now, I could have purchased a new USB air card and swapped between the two, but opted for the ‘cooler’ toy the Sprint MiFi. The MiFi is an air-card and 5 user wireless router all in one tiny package. So, using my current data account, I can now share a wireless (Wifi) connection for upto 5 devices. Now, I can have both my laptop and netbook online – all at the same time.
No more plugging in a usb device into the laptop. No more applications to run. Simply connect to a Wifi account an you are good to go. And now you can share the signal if needed.
The device is about the size of a credit card and slips into my top pocket. Takes a few seconds to go from on to broadcasting the Wifi SSID. The only drawback is battery life, and the more users or bandwidth used, the faster it drains. I usually only need it for short durations, but towards the end of a day it is wasted. Unfortunately, you cannot plug the USB into the laptop and keep it charging while using it. You can plug the ac adapter in, but that doesn’t do much for you one the road. I did discover that you can keep it chaaring by plugging it into a 12V usb car adapter via a usb cable.
So, for all you mobile air card users, the MiFi is the way to to go….
