3 Steps To Securing Your Business’ Wireless Network
By Data Installations & Supplies ltd
Whether you’re reading this at home, in the workplace or on the go, chances are you’re either connected to a wireless network right now, you own one or you frequently connect to one. It may not be something that you take into consideration, but with cyber attacks increasing steadily over the past decade or so, it’s more important than ever to set up effective WiFi security measures on domestic or office WiFi networks. Taking the current climate of coronavirus and an uptick in home working into consideration, wireless network security for the home is just as important as those in a business environment.
Luckily, there are a few simple steps you can take to drastically improve your business internet security!
Every domestic or business wireless network should have a password on it. The only time this might not be necessary is if you’ve set up a guest network that’s only accessed by visitors or customers, but this should still be configured correctly to prevent any guest users having access to your business’ sensitive information.
However, just having a password isn’t enough in this world of advanced technology. Depending on the age of your router, it may be using the WiFi encryption protocol WEP (Wired Equivalent Privacy) which is extremely susceptible to cyber attacks due to a number of weaknesses. The most secure encryption protocol currently is WPA2 (WiFi Protected Access) so make sure this is what your router is using as its password protocol. You can also combine this with EAP-TLS (Extensible Authentication Protocol Transport Layer Security) for even more WiFi protection, however there is a trade-off at play between security and convenience to be argued here.
Using WPA2 is a great step towards a secure wireless network, but the actual password you use is vitally important too. If you use something obvious, such as the word ‘password’, sequential numbers or your company’s name, it’s incredibly easy for hackers to access your network and therefore your data. When creating a password, keep the following guidelines in mind:
Make it long: keywords should ideally be over 15 characters long to maximise security.
Mix up your characters: a combination of upper- & lower-case letters with numbers and symbols is the perfect recipe for a potent password.
Accept no substitutions: swapping letters for lookalike numbers (i.e. HELLO becoming H3LL0) is an obvious tactic, so random character placement is a lot more powerful.
Despite their name, cyber attacks can also occur in person if a hacker can gain access to your premises. Evading corporate internet security protocols can sometimes be as simple as resetting a router so ensure that you keep it in a physically secure location! Most businesses opt for a locked, heavy duty cabinet but if you have a large amount of servers, a dedicated room with a lock and surveillance is ideal. Once your network has been set up, it’s likely that you won’t need to access the router very often so this level of security shouldn’t be too much of an inconvenience for yourself and staff members.
Other physical access points that can be exploited are Ethernet ports. A hacker within your company, a trespasser or a guest can access sensitive or secured information easily by plugging a device into one of these ports around your premises. You can deal with this in three ways; un-patch non-essential Ethernet ports around the building, disable unused switch ports on your network or use smart features like port security throughout your network.
Guest WiFi Security Measures
Whilst it’s not necessary for a lot of businesses to provide a wireless network for visitors or customers, it’s an appreciated gesture and is becoming more and more expected. In the food service industry, such as coffee shops, cafes or restaurants, more and more establishments are providing a way for guests to get their devices online without using their mobile data.
If you’re planning on offering this, make sure that you either set up an entirely new network and router to offer this service, or that you separate your employee and public networks with a Service Set Identifier (SSID) to allow for two different access points. This also isolates your business’ computers from guests and allows you to utilise different WiFi security types.
