This article contains some simple steps on how to Secure Wireless Network. Of course, your WiFi should be secured always so that you can restrict people from accessing your Internet without your permission. Many people setting up wi-fi rush through the job to get their network working as quickly as possible. It’s also quite risky as numerous security problems can result. That doesn’t mean you shouldn’t use wireless networking. You just have to be smart about it and take some basic precautions to make it more difficult for curiosity seekers to get into your personal information. Today’s wireless networking products don’t always help the situation as configuring their security features can be time-consuming.
1. Change router log in Passwords (and Usernames)
Router setup page is the page where you can change the settings manually. This web-page is protected with a log in screen (user name and password). The default user name and passwords are very simple and well known. Change the default user name and password of Router setup page.
2. Secure Wireless Network using WEP / WPA / WPA2:
There is encryption technology for the security. This Encryption technology scrambles messages sent over the wifi so that they cannot be easily read by humans. Several encryption technologies exist today to secure wireless network connection. Naturally you would like to use the strongest encryption that works to secure wifi. However, all Wi-Fi devices on your network must share the identical encryption settings.
WEP, WPA and WPA2 are the most common types used for the security.
WEP stands for Wired Equivalent Privacy. A WEP key is a security code used on some Wi-Fi networks. WEP keys allow a group of devices on a local network to exchange encoded messages with each other while hiding the contents of the messages from easy viewing by outsiders.
A WEP key is a sequence of hexadecimal digits. These digits include the numbers 0-9 and the letters A-F. Some examples of WEP keys are:
WPA stands for Wi-Fi protected access. WPA improves on the authentication and encryption features of WEP. WPA was developed by the networking industry in response to the weaknesses of WEP. WPA provides stronger encryption than WEP through use of either of two standard technologies: Temporal Key Integrity Protocol (TKIP) and Advanced Encryption Standard (AES). WPA also includes built-in authentication support that WEP does not offer.
WPA2 (Wireless Protected Access 2) replaced the original WPA technology on all certified Wi-Fi hardware since 2006 and is based on the IEEE 802.11i technology standard for data encryption.
3. Change the wireless network name:
SSID is the name of your wireless network connection. Open the setup page of the router and change the SSID so that you can identify your own wifi.
4. Enable MAC Address Filtering on your router:
Access points and routers keep track of the MAC addresses of all devices that connect to them. Many such products offer the owner an option to key in the MAC addresses of their home equipment, that restricts the network to only allow connections from those devices. Do this, but also know that the feature is not powerful as it may seem. Hackers and their software programs can fake MAC addresses easily.
