Vienna, Virginia (VA) Wireless Router Encryption –Wireless Router Encryption For Home Networks Vienna, Virginia (VA)

Most home networks these days are wireless and it is very important that we protect the data that we have on our computers and the information that we are sending over the internet.  One of the worst feelings in the world is finding out that our system has been hacked and we now have a virus on our computer or even worse our identity stolen.  Encryption also keeps random people from jumping on to our wireless networks for free internet usage.  If you have a network and only use the default security, where WEP or WPA is turned off, any random person can jump on to your network and use your internet connection.  The two most common forms of encryption for home networks are WEP and WPA/WPA2.

WEP or Wired Equivalent Privacy is the lowest level of encryption.  This is basically one step above the default security and it will enable you to lock your network so that people can’t access it without your permission and an encryption passkey.  WEP is very easy to configure and has three basic settings:

1.       Off – no security

2.       64-bit – weak security

3.       128-bit – better security

The downfall to WEP is that it can be easy to crack and it can slightly reduce your performance, but probably not enough to notice.

WPA or Wi-Fi Protected Access is a wireless security with more protection than WEP.  WPA is newer form of security than WEP that offers a higher level of security.  A few disadvantages to WPA are that all the computers, access points and adapters must have WPA software; it won’t be compatible with older operating systems such as Windows 95, and any equipment older than 2003 won’t be upgradable, because WPA wasn’t introduced until 2003.  WPA has two major advantages over WEP:

1.       Even if hackers intercept the data, it will be difficult for them to read because the TKIP (Temporal Key Integrity Protocol) mechanism shares a starting key between each devise but then each devise will change their encryption key for every packet.

2.       A Certificate Authentication can be used which will stop a hacker acting as a legitimate user, from accessing data.

Encrypting your data is extremely important and you need to make sure that your network is secure.  If you have questions or concerns about your specific Wi-Fi security and encryption or need help securing your Wi-Fi connection, Geek ABC is here to help, you can reach us via our website, www.geekabc.com, or give us a call at 1.877.GEEKABC (1.877.433.5222) to schedule an appointment.  Our computer geeks can help you set up a new wireless network if you don’t already have one and can help you set up the level of security that you require to keep your information safe.  We provide same day, mobile, in-home computer and network support and repair services for residential and business customers in the Washington, DC Metropolitan area.

Fairfax Virginia (VA) Wireless Network & Router Encryption – Wireless Network & Router Encryption For Home & Small Business Users

Just about everywhere you go, today, there seems to be a Wi-Fi connection that you can hop on, if you wanted to.  Public places such as coffee shops, cafés, hotels, libraries, and college campuses, for the most part, have a Wi-Fi connection that you can use if you are a guest, customer, or student.  But these aren’t the only places you will find Wi-Fi, most home users, these days, have a wireless network set up with Wi-Fi so that they can use their computers in every part of the house or to wirelessly connect other electronics such as printers, PDA phones, gaming consoles (Wii, Xbox, PlayStation), netbooks, iPods, iPads, and other Bluetooth/Wi-Fi devices.

When you have a wireless home network set up, the users need to be aware of the possible dangers that exist.  Without proper encryption you may face situations like hackers attempting to steal your personal information, as well as possible, virus, malware, and/or spyware intrusions.  It is extremely important to have your router properly encrypted and to be aware of the encryption standard/method that is being used.  Current routers on the market today offer at least two forms of encryption, WEP and WPA/WPA2.

When you set up your wireless network it is important to make sure that your connection is secured and show’s as “locked”.  This will keep out nosy neighbors or random hackers from accessing your internet connection with out your permission.  For the most part people are just looking for a free connection but there are hackers out there who are looking for unsecured networks that the can get in to for the purpose of stealing information.

I plan to go into further detail about WEP and WPA/WPA2 encryption in a future blog.  What they mean, what the differences are, and which one might work best for you.

Arlington, Virginia (VA) Computer Network Security – Arlington, Virginia (VA) Home Computer Network Security

Home Computer Network Security is a big issue these days.  Computer networks are becoming more and more popular due to fact that we tend to have more than one computer in the home or workplace and specifically our need for mobility.  Who doesn’t want to be able to use their laptop in every room of the house without having to have a direct wire to the modem or router?

Having a home computer network doesn’t necessarily come easy, you have to make sure that your networks are secure and do everything you can to make it virtually impossible for intruders to get in.  If you have a home network set up and need help with security, Geek ABC’s computer geeks are here to help, you can reach us via our website, www.geekabc.com, or give us a call at 1.877.GEEKABC (1.877.433.5222) to schedule an appointment.  We provide same day, mobile, onsite network support and repair services for residential and business customers in the Washington, DC Metropolitan area.

These days we use our computers for just about everything online such as shopping, banking, and keeping in touch with our family, friends, and coworkers through email and chat programs.  And even though we don’t necessarily view these communications as “classified”, we don’t really want just anybody reading our emails or chat sessions, or even worse, someone hacking in to our system and obtaining access to our banking and credit card information which can lead to identity theft.

There are a number of things you can do to secure your home network and keep you safe from viruses, malware, spyware which all can lead to an eventual computer crash and hackers which can steal our information and possibly our identities.  Having proper network security will also prevent others from logging in and using your network to gain access to the internet without permission.

Here are a few things you can do to help insure that your computer (pc) is protected (in no specific order):

  • Make sure that you have some version of antivirus software installed on your computer.  And just having the program is not enough, you have to run frequent scans and keep your virus definitions up to date.
  • Create “strong passwords” when you are creating any of the passwords for your computer or online.
  • Use a firewall.
  • Don’t run or open programs of an unknown origin.  Unless the program is authored by a company or person you trust, don’t run/open it.  It could contain what is called a “trojan horse program”.
  • Turn off your computer or network when it’s not in use.
  • Make sure that you encrypt your router.  There are various types of encryption options available, it’s best to look at the manual and choose the one that works best for you!
