Quick Tips On How To Remain Secure When Using Wireless Hotspots!

Friday, February 25th, 2011

Wireless hotspots exist almost everywhere today. Whether you are at your favorite fast food restaurant, hotel, bar, hospital, airport, or anywhere in between you most likely have access to a wireless hotspot. These Wi-Fi resources are extremely convenient and allow users to access a network in order to complete work, check email, or just surf the net. The one thing of concern however is their susceptibility to security intrusions. Wi-Fi hotspots do not encrypt their data, consequently leaving your information vulnerable to hackers.

When utilizing a wireless hotspot it is important that you take the following necessary precautions to keep you and your information protected:

Safety over Convenience:

Although it might be tempting to sign onto any network in order to get your work done it is not the smartest or safest choice. It is advised that you try to locate secure VPN locations that require a login access key. The locations may not be as convenient as the place that enable keyless network entry but they certainly offer more safety.

Prepare your computer for unwanted exposure:

When you need to the access the Internet it might not always possible to access a hotspot that is secure, so it is important that you prepare your computer to the best of your ability. In order to prime your computer for any unwanted security intrusions you may want to try the following:

Disable your Wi-Fi settings when not using it!

When not using Wi-Fi, access your settings and turn it off. If left on your device can access hotspots that could contain threats to your personal information.

Ensure that you are utilizing an active and up-to-date firewall!

Firewalls can be enabled in the security section of your computers control panel.

Disable File and Printer Sharing!

To access your file and printer sharing settings go into your control panel, click to open the computer network and internet folder, and adjust the network and sharing menu.

Encrypt your files!

Encrypting your files can be achieved by right-clicking the folder or file that you want to encrypt, clicking Properties, clicking the General tab, and then clicking Advanced. From here select the Encrypt contents to secure data check box, and then click OK.

Leave private information at home!

Unless it is absolutely necessary, try to avoid keeping important and private information on your portable computer. If you have a desktop computer at home use it house any critical data as opposed to carrying it around where it is exposed to more risk.

Don’t forget about physical protection:

It is equally if not more important to remember that your actual computer is exposed to just as much risk as the information contained on it. Don’t leave your computer unattended where someone can access it or even worse, can take it!

These are just a few of the basic quick tips to consider when working from wireless hotspots.

Have a Great Day!

Wireless N – What You Need to Know Before You Buy

Hey, everyone, Josh from Computer Fitness back with another award-winning article to help you with your computer conundrums.

Wifi has been around for years now. It has grown and expanded into something that is a part of our daily lives. For years, Wireless G was the standard by which all wireless devices were designed. However, recently, Wireless N has taken over as the new goal for developers and technological enthusiasts. Now, a lot of websites and products will talk about Wireless N and how you need it desperately. Here are some things you should know about Wireless N before you proceed.

It Is Faster than Wireless-G

Now, Wireless N is definitely faster than Wireless G. You can send enormous amounts of data over a Wireless N network in a fraction of the time it would take on a G network. This is great for streaming video and audio inside of your home or office, as well as moving around files for backup.

Requires a New WiFi Card

Your old G card won’t cut it here. This is a new wireless standard and, as such, requires new hardware. Don’t you just love technology? So before someone at a big box retail store tells you that you need a Wireless N router, account for the necessary new hardware you’ll have to buy as well.

There is No Internet Connection Fast Enough

While N is faster than G, there is currently no Internet service out there that can match the speeds. At most, your local ISP (Internet Service Provider) could offer something that uses 10% of your Wire

Less N connection. So remember, you don’t NEED Wireless N unless you’re moving data around your house a lot. A good example here is streaming video wirelessly from a desktop to a TV.

Is Bluetooth Beneficial or a Disaster Waiting to Happen?

Wednesday, June 30th, 2010

bluetoothHey, everyone. It’s Josh from Computer Fitness again. We are a Tech Support Company for Small and Medium businesses located in Reisterstown, MD.

Most people today is familiar with Bluetooth technology. It’s not universal yet, but lots of devices use it. The most common use of Bluetooth is wireless headsets for cell phones. Bluetooth is designed to facilitate something that we tech nerds call the PAN, or Personal Area Network. This is just like a WAN or LAN, however the scope is incredibly limited, specifically, to your person. It has a lot of really cool applications, but there are also some drawbacks.

Benefit: Limited in Scope

This may seem like a drawback for some users, but this is actually a positive. It keeps people from having too many connections overlapping each other. Also, it prevents others from trying to join your PAN all the time.

Benefit: Many Connections Available

Bluetooth functions a lot like Wireless networks, so it supports multiple connections at once. While the bandwidth is not especially great, you can easily support several devices. Typically, in the case of computers, you will see a keyboard, mouse, and headset using Bluetooth to connect. Room still exists for other devices as well.

Drawback: Bluetooth isn’t 100% Secure

Most techs will also tell you that Bluetooth, while a great technology, is not especially secure. Most devices use very simple PINs to enable security/attach to a network. Sometimes, these devices use the standard default password of 0000. Bear this in mind when using Bluetooth.

Potentially Problematic Interactions: Why You Need to Carefully Consider Wireless Technology Choices

Thursday, April 29th, 2010

wi-fi overlapHello and welcome to Computer Fitness’ Blog! My name is Josh. You may know me from the Internet Beacon. We have a pretty cool blog over there. If you’re new to our sites, do check it out; there’s plenty more awesome over there. Computer Fitness is a tech support firm in Finksburg, MD. Our areas of expertise run the gamut from desktop repair to server maintenance.

Certainly a wireless world makes things a lot easier. Think about all the wireless technology you own. It could be a lot or just a cordless phone for your landline. If it’s just the phone, maybe grab some new stuff. That’s just me. We tech folks tend to push for the latest and greatest. However, there are times when you need to carefully consider which technologies you employ.

In this case, wireless technologies often operates on the same frequency. That frequency is the 2.4ghz range. This frequency is the standard for wireless devices and, as such, can be a bit problematic on occasion. Think about your cordless phone, wireless router (Wireless A/B/G 802.11), wireless mouse, etc. all talking on the same line. It can be troublesome.

The best way to avoid this is to make sure there is enough space between the devices. I know this may sound like a simple solution, but it has proven to be the best one. For example, many people have their desktop computers right next to their routers. Not everyone, but a lot. If you have a wireless mouse broadcasting on the same frequency as the router, you may notice your mouse being a bit jumpy or unresponsive at random times. This is because two different data streams are broadcasting on the same frequency in close proximity. In this case, it might be best to just switch to a wired mouse. This is just one example of a potentially problematic interaction.

In the end, just make sure that you give your devices enough space to function properly. And, if it means being mildly inconvenienced to ensure they all play nice together, it’s worth it. That’s all for this week. Come back again for more Computer Fitness tips.
