Wireless Security: Top Four Protections
The risks inherent in wireless networks are numerous but not unknown. Although many vulnerabilities exist in default wireless implementations, there are many techniques that may be employed to protect your network from unwanted intruders.
This top four list describes some of the possible methods that may be appropriate for securing many applications of wireless networks. The list, however, is not appropriate for every application, nor is it an exhaustive overview. If you seek confirmation that your wireless network is secure, contact an expert that can review your network with available technology and protection methods to find a solution that fits your needs.
Securely Configure Your Existing Equipment
- Change the Default Administrator Password. All wireless routers have administrative accounts that allow you to set features and security controls on the wireless router. Out of the box, these accounts have either no password or a well-known default password for easy initial access.
Turn on Encryption. Out of the box, most routers come equipped with built-in encryption turned off. This basically is a password for your network. This will usually prevent others from using your wireless network without your permission or knowledge.
Change Default Network Name. The name of the network is its identification. By default the network name will be common such as “default” or the name of the wireless router manufacturer.
Don’t Broadcast the Network Name. To connect to the wireless network you need, at a minimum, the name of the network. It is usually good practice not to broadcast this name. By not broadcasting, others within range of your wireless network will not see that your wireless network even exists.
Tips For Securing Your Wireless Network
- Don't change the Network Name to your street address or name.
- Think about assigning static IP addresses for your wireless NICs and turn off DHCP.
- If you're using a wireless router and have decided to turn off DHCP, also consider changing the IP subnet.
