How to secure your wireless network


When setting up a wireless network for your business, it can be tempting to leave some security functions switched off. People rather get work done, than spend time on preventing events that may never occur. However, when they do, the consequences can be serious. Bearing this in mind, all businesses have to make sure that their networks are secure.

It is important to remember, that you can’t keep your wireless network within your premises. Anyone within range of an unsecured network may gain access. This means that not only can outsiders use your internet for free, but they can potentially intercept your passwords, financial information and customer records, leaving you vulnerable to a serious breach. suggests three ways of making your wireless secure:

Use encryption

Encryption is possibly the most important measure you can take to secure your network. Most likely all routers and wireless devices offer some form of encryption these days. Encrypting a network involves creating a password that is hard to break. Note that, not all forms of encryption are perfectly secure though. For instance WEP, the most basic and oldest form of wireless encryption is no longer considered secure, as hackers can crack it within minutes. WPA and WPA2 on the other hand are much more secure, as they were developed to overcome all weaknesses of their predecessor.

Use a firewall

Hardware firewalls provide the first line of defense against attacks coming from outside of the network. Most routers have firewalls built into them, which check data coming in and out and block any suspicious activity.
Most firewalls use packet filtering, which checks the header of a packet to figure out its source and destination addresses. This information is compared to a set of predefined and/or user-created rules that govern whether the packet is legitimate or not.

Software firewalls usually run on the endpoint desktop or laptop, with the advantage of providing a better idea about the traffic that’s passing through the device. 
Get your router settings right

  • Change the router's access name and password
  • Change the default network ID
  • Stop your router broadcasting its network ID
  • Enable MAC authentication for your users
  • Create a separate wireless network for your customers
