For businesses in Omagh, a reliable Wi-Fi connection is now as essential as the phone or electricity supply. From emails and card payments to cloud software, online banking and customer services, businesses rely on wireless networks every day. But if your Wi-Fi is not properly protected, it could also provide an opportunity for cyber criminals to access important business information.
The good news is that improving your wireless security does not always require complicated technology. A few practical steps can make a big difference.
Why secure Wi-Fi matters
Cyber attacks are not just a problem for large companies.
Small and medium-sized businesses can also be targeted, particularly where security settings have not been updated or default passwords are still being used.
For a local business in Omagh, a cyber incident could disrupt day-to-day operations, prevent staff accessing important systems or put customer and supplier information at risk.
It can also damage the reputation and trust that many local businesses work hard to build.
Check your Wi-Fi security
One of the first things businesses should do is check the security settings on their router.
Older security systems, including WEP and some early versions of WPA, are no longer considered secure.
Businesses should use WPA2 or, where available, WPA3. WPA3 is the newer standard and offers stronger protection.
It is also important to change any default password that came with your router.
Choose a strong, unique password that is difficult to guess. Longer passwords are generally more secure, with guidance recommending passwords of 20 characters or more where possible.
Keep routers and equipment updated
Just like computers and smartphones, routers receive software updates.
These updates can fix security weaknesses, so businesses should make sure their router and other network equipment are kept up to date.
Automatic updates should be enabled where available.
If you are using an older router that is no longer supported by the manufacturer, it may be worth considering a replacement.
Separate customer and business Wi-Fi
Many Omagh businesses, including cafés, shops, hospitality venues and professional services, may offer Wi-Fi to customers or visitors.
Where possible, customer Wi-Fi should be kept separate from the network used by staff and business systems.
Creating a guest network can help prevent visitors from accessing devices, files or systems used to run your business.
Businesses should also regularly check which devices are connected to their network and investigate anything they do not recognise.
Think about remote working
More businesses are allowing staff to work remotely or access systems while away from the office.
Public Wi-Fi in hotels, cafés and other shared spaces may not always be secure.
Businesses can reduce the risk by encouraging staff to use secure connections and, where appropriate, a Virtual Private Network or VPN when accessing company systems remotely.
Make cyber security a regular habit
Protecting your Wi-Fi should not be a one-off job.
Businesses should regularly check their security settings, update equipment, review connected devices and change passwords when necessary.
If you are unsure about the security of your network, speaking to an IT or cyber security professional can help identify potential weaknesses.
Taking a few simple precautions now could help avoid costly disruption later.
