WiFi Security

5 ways that SMEs can improve their Wi-Fi security

Most SMEs will use Wi-Fi within their business, however many companies are unaware that this can pose security risks if it is not secured properly. Even if you’re no expert, there are a number of things that you can do to improve your Wi-Fi security:

#1 Password reset

The first thing to do, and that Building Zones do when we provide customers with a new router, is to reset the standard admin password on the router. Default passwords are easy to find online and accessible should someone want to log in and take control of your network with malicious intent. This simple change is a great first step in ensuring that you remain in control of your network.

#2 Create a passphrase for your secure network

As well as the router password, you also need to implement a password in order for users to connect with the Wi-Fi. This should be something complex including numbers, lower and uppercase letters and symbols where possible, using at least 8-10 characters. Avoid using full words or names that may be easy to guess, and make it as random as possible to provide the highest protection against cracking.

#3 Firmware updates and disabling WPS

Updates are critical to ongoing security, so updating your router is just as important as updating your phone, computer and apps on a regular basis. This enables any big fixes for better service, which can make your Wi-Fi performance even better. Similarly, disabling Wi-Fi Protected Setup (WPS) is essential. Despite providing easier access, this highlights an area of security weakness, so it is best practice to turn off and disable this feature.

#4 Utilise guest Wi-Fi

Visitors to your offices or work location should not be given free access to your Wi-Fi network through your standard password. This opens up access to their devices, which can be infected with malware and other viruses which can then get onto your network and cause a whole range of issues. You can reduce this risk by setting up a dedicated visitor access as a “Guest network” to your router, which gives them internet access without access to any other devices within your network.

#5 Physical router security

Along with all these practicalities, the location and physical security of your Wi-Fi router should not be forgotten. A single button can reset all the security you have implemented, so restricting access is vital. It is recommended that routers should be kept in a locked cabinet or room, or at least hidden from view in an inconvenient location such as close to the ceiling, where anyone accessing it will be more obvious.

Leave it to the professionals

Ultimately, the best way to guarantee the absolute highest levels of security is to leave it to the professionals. In-house processes are no match for connectivity specialists who understand both basic requirements, and specific industry security regulations. Building Zones specialise in working with businesses across the education and hospitality sectors, as well as venues and office locations.
