How to Safeguard your network

How to secure a wireless network

to this problem. Use WEP Encryption on your router to safeguard your network. Here’s how you can go about doing it. 

  • In your Internet Explorer address box, enter the IP address of your router.
  • Log into your router page and click on the Wireless tab.
  • Here’s how a Linksys router page looks. You could use it as a guide to work on your router page.

  • Select the mixed option under Wireless Network Mode.
  • Enter any name you want in the Wireless Network Name – SSID box.
  • Select the 6 - 2.437GHz option in the Wireless Channel box.
  • Enable the SSID Broadcast option.
  • Click on the Save settings button.
  • Now click on the Wireless Security tab.
  • Select the WEP option under Security mode.
  • Select 64 bits 10 hex digits or 128 bits 26 hex digits option based on the encryption key you want to generate.
  • In the Key1 box enter the 10 digit number for 64 bits encryption or 26 digit number for 128 bits encryption.
  • Click on save settings.

This set of numbers will be the password for your network and your network is now a secured network. You will see your network listed on your wireless computer. You can log into your network using the password or network key you generated.

  1. Click on Start and select Programs.
  2. Now go to Accessories and select System tools. Now click on Security Center

  3. Click on Windows Firewall

  You can now turn ON or OFF the firewall as desired.

  • Click on Start, and then select Control Panel.
  • Now click on Network and Internet Connections, and then select Network Connections.
  • Under the Dial-Up or LAN or High Speed Internet category.
  • Select the icon of the connection you want to help protect.
  • In Network Tasks, click Change settings of this connection
  • On the Advanced tab, under Internet Connection Firewall, make sure the box is checked next to Protect my computer and network by limiting or preventing access to this computer from the Internet. If a check mark is in the box, the firewall is already enabled.

Am I being pinged, probed or attacked on this port

The ideal way to safeguard your system is by using a firewall. Make sure your firewall is enabled at all times. Your firewall will record all the events. So at any point of time you can figure out if anybody has tried to access your system without authorization. You could use the Security Scan tools available in the market to figure out which ports are open in your computer. Hackers usually try their luck on dozens of ports looking for that one vulnerable port that they can use.

  • If you notice repeated activity from a particular IP address on a port that is closed, then it could be the work of a worm or virus trying to wriggle its way into your system. You can run your anti-virus program to get rid of this.
  • Take a look at your firewall log. You can also use some of the free services available on the internet like myNetWatchman and Dshield to analyse your firewall log to determine if anybody is trying to hack into your system.
  • From your firewall log determine the IP address you are using. Figure out if it belonged to an active server. In that case the events you see might just be due to someone genuinely trying to contact the server. This problem will go away in a couple of days.
  • Try to collect all the information you can about the usage of your port. Be informed about the common software and malware that use the port.

If your software or a virus isn't using the port or if the events are blocked by a firewall you have no immediate concern.

What is WEP

WEP - Wired Equivalency Privacy is a type of encryption used initially as an attempt to secure wireless networks. . Turning off your WEP will allow anybody in your vicinity to easily log into your network and access your system. WEP like all security protocols had its own set of pros and cons and professional hackers can find a work around these.

WEP is popular as a security measure for your wireless network due to its easy usability. Newer and better security measures like DES, Mac address filtering and WPA are now available.

WEP encryption is of two types with the 64bit 10 hex digits and 128 bits 26 hex digits encryption. The latter though slightly more secure also tends to reduce your system performance.

Changing your WEP key often will increase the level of protection to your network.
