Tips To Secure Your Wifi Connection
1.
Install a Firewall A firewall helps protect your PC by preventing unauthorized
users from gaining access to your computer through the Internet or a network.
It acts as a barrier that checks any information coming from the Internet or a
network, and then either blocks the information or allows it to pass through to
your computer.
2. Change the Administrative
Password on your Wireless Routers Each manufacturer ships their wireless
routers with a default password for easy initial access. These passwords are
easy to find on vendor support sites, and should therefore be changed
immediately.
3. Change the Default SSID Name
and Turn Off SSID Broadcasting This will require your wireless client computers
to manually enter the name of your SSID (Service Set Identifier) before they
can connect to your network, greatly minimizing the damage from the casual user
whose laptop is configured to connect to any available SSID broadcast it finds.
You should also change the SSID name from the factory default, since these are
just as well-known as the default passwords
4. Disable
DHCP For a SOHO network with only a few computers, consider disabling DHCP
(Dynamic Host Configuration Protocol) on your router and assigning IP addresses
to your client computers manually. On newer wireless routers, you can even
restrict access to the router to specific MAC addresses.
5. Replace
WEP with WPA WEP (Wired Equivalent Privacy) is a security protocol that was
designed to provide a wireless computer network with a level of security and privacy
comparable to what is usually expected of a wired computer network. WEP is a
very weak form of security that uses common 60 or 108 bit key shared among all
of the devices on the network to encrypt the wireless data. Hackers can access
tools freely available on the Internet that can crack a WEP key in as little as
15 minutes. Once the WEP key is cracked, the network traffic instantly turns
into clear text – making it easy for the hacker to treat the network like any
open network. WPA (Wi-Fi Protected Access) is a powerful, standards-based,
interoperable security technology for wireless computer networks. It provides
strong data protection by using 128-bit encryption keys and dynamic session
keys to ensure a wireless computer network's privacy and security. Many
cryptographers are confident that WPA addresses all the known attacks on WEP.
It also adds strong user authentication, which was absent in WEP.
