Protective Guidelines for WiFi Threats
There are several measures that you should take to maximize the safety of your emails, sensitive information,
and other assets. Here are some tips that you can observe to protect yourself from WiFi risks; these include:

✓ Change default passwords.
Your first line of defence in protecting your device is to use complex passwords and periodically
change them.
✓ Restrict access.
Each hardware that is connected to a network has a media access control (MAC) address. Therefore,
you have to restrict access to your network by filtering out these MAC addresses.
✓ Encrypt the data on your network.
Encrypting your wireless data prevents anyone who might be able to access your network from
viewing it. There are several encryption protocols available to provide this protection. Wi-Fi Protected
Access (WPA), WPA2, and WPA3 encrypt information transmitted between wireless routers and
devices.
✓ Protect your Service Set Identifier (SSID).
You have to avoid anyone from quickly accessing your network by hiding your SSID. All Wi-Fi routers
allow users to protect their device's SSID, which makes it more difficult for attackers to find or detect
a network.
✓ Install a firewall.
Consider shielding your home network by installing a firewall directly on your wireless devices (a host-
based firewall) and your home network (a router or modem-based firewall).
✓ Maintain antivirus software
Install antivirus software and keep it up to date. Many antivirus programs also have features that
detect or protect against spyware and adware.
✓ Be cautious when sharing files.
File sharing between devices should be disabled when not needed. You should always enable file
sharing only over the home or work networks; never enable it on public networks.
✓ Keep your access point software patched and up to date.
Check the manufacturer's website regularly for updates or patches for your device.
✓ Check your internet provider's or router manufacturer's wireless security options.
Your internet service provider and router manufacturer may provide information or resources to
assist in securing your wireless network.
