Wireless networks have become common these days. These days, almost all homes have wireless routers or wireless access points. However, the technology has security issues, especially if you do not follow safe practices. If you network security is breached, you could loose your important data like your credit card or bank information. Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) I and II are the protocols that handle security in wireless networks.
While setting up the wireless network on your computer, you will need to set up one of the above mentioned wireless access security protocols. It will secure your computer and data from unwanted sharing. You will need to set up a password for authentication purpose. Make sure that you give the password only to those individuals who you want to get connected.
Ways to secure your computer in the wireless network:
Security password of networks is not something that can be taken lightly. You cannot let your network access get into the wrong hands. Most of us do not even bother changing the default password. In fact, it is the first step to establish a secure wireless network.
Below mentioned are some important measures to secure your wireless networks from unauthorized access:
- Changing the default network password to something more secure.
- Always use such a strong password that would be hard to guess by anyone.
- Password should not be a dictionary word. Ideally it should be a long string with a combination of alphanumeric letters and special characters.
- Always select WPA authentication security protocol. If it is not available, then at least use the WEP protocol for wireless network security.
- SSID (service set identifier) is the name of the network you are creating. You can block displaying the name of the SSID to everyone. By doing this, only those people who know your network SSID will be able to connect to your network.
- DHCP is dynamic host configuration protocol. In order to secure your wireless network, you could assign network SSID manually to different users. It is a great way to tighten your wireless network security.
- Next, you can block anonymous network connection request from pings.
- Peer to peer connections should not be allowed from your network.
- For a more enhanced security you can enable MAC (media access control) filtering for users. By doing this, only those computers can connect to the network whose MAC address is already registered in your network. Only those devices with registered MAC addresses will be able to connect to your network.
- The network router must permit the firewall features, and they must be enabled.
- All connecting computers must have a personal firewall, which is in addition to the default network firewall.
- Complete updating process of router / access point regularly as soon as new versions are available.
You may not be able make your network completely secure by adopting just one of the security measures mentioned above. However, a combination of multiple security measures will give enhanced and unbreakable security to your networks.
