Question

What controls must be used to protect data that is transmitted across wireless networks?

Answer 1

Controls that must be used to protect data that is transmitted across wireless network:

1. Enable encryption:Encryption is one of your first lines of defense when it comes to securing a wireless network. It encodes the data sent wirelessly between your device and the router, essentially scrambling the information and restricting open access.

2.   Change the router defaults:Make sure to change your router’s factory presets (i.e. your admin login and password) to something more secure to prevent any unauthorized users from accessing and changing your router settings.

3.   Turn off SSID broadcasting:The SSID functions as a broadcast message that notifies your presence to any and every device within range of your network. All wireless routers have an option to turn off this broadcast, which hides your network from people who may want to access it.

4.   Allow access based on MAC addresses:Every network-enabled device – from desktops to tablets – is equipped with a unique, identifying number called a Machine Access Code (MAC). Most common wireless routers will have an option to filter access solely based on the MAC address, allowing wireless access only to devices you have preapproved and prohibiting all others.

5.   Limit DHCP:Dynamic Host Configuration Protocol (DHCP) allows you to limit the number of IP addresses your router can assign on your wireless network, thus limiting the amount of devices that can connect.

6.   Disable remote administration privileges:Disabling remote administration privileges is a great way to close the door on anyone looking to access your security settings.
