The Ultimate Wireless Firewall: Networks That Don’t Connect
Author: John ScheblerNetwork security has become a major concern for any business connected to the Internet. Hardly a day goes by that we don't see another announcement of retaliatory measures from the company. We only see the tip of the iceberg. Public reports mostly involve companies whose customer information, especially credit card numbers, has been compromised. Other companies may discover breaches that do not affect their customers and may decide to remain silent to avoid embarrassment and press trouble.
Who can afford cyber security?The result of all this hacking and cyber warfare is that IT departments are on high alert. If they remained connected to the Internet, they would have no choice but to pay for security devices and network security in the cloud. But what about small and medium-sized enterprises? Can a regular doctor's office or restaurant really pay for cyber defense?
health measures
Of course, any freelancer or small business can take basic common sense steps to prevent hackers and regular hackers from finding the fruits of their networks. Almost every router also includes a firewall and encryption feature for accessing the Wi-Fi network. Those who ignore changing their default login and password and enable the highest level of encryption on their devices are not easy to talk to.
Public access is always at risk
However, doubts remain about the security of the network. When you unblock Wi-Fi access for clients to use your hotspot, you run two risks. First, you open a hole in the security. The vast majority of your customers will use broadband just for convenience. They are not going to bother you. But... there are characters with malware on their laptops who can pretend to be other customers or try to break into your network. These days, Wi-Fi doesn't stop at the door, so you can park outside or even sit a block away.
just the cable?
The safest solution is to use only wired access in the company and refuse Wi-Fi altogether. This can really limit you and your employees by eliminating any portable or mobile devices. The next step is to have a Wi-Fi router that is locked for employee use only. This frustrates customers and guests as they want to use their tablets while waiting.
Will the firewall work?
Is it enough to simply install a firewall between your business network and a public Wi-Fi hotspot? This idea makes many business people nervous. It's hard to say, especially if you don't have a full-time IT department monitoring everything, whether you're actually protected or not. So they choose to shut down their wireless network or not have one at all.
two network solutions
Here is another way. Install two grids instead of one. The first is your internal business network. This can be high-performance Ethernet with copper bandwidth or fiber. It may not even connect to the Internet. In both cases, connect devices only to this network. If you have wireless access, turn it off. Then find a second internet connection. This option is for your customers and does not require the performance specifications of your core network. Cable broadband is a good option for many small and medium-sized businesses that work with the public as well as at home.
Why Cable Broadband?
The beauty of broadband cable is that it is cheap, even for workplaces. It has a good bandwidth of 10 to 100 Mbps and is very reliable these days. There is a bonus for companies with customer waiting areas. You can bundle your cable TV service with broadband for a small additional fee. You can still service the TV. Why not add broadband as an added convenience?
keep them away
Here's what not to do. Never connect your business network to a customer network. They stay completely separate. If you get them from different suppliers and keep the wires separate, there is no chance of confusion. If someone sits outside at night and steals your broadband signal or tries to break into your public wireless network, you won't get very far. It's not really connected to anything other than the internet.
What about your basic internet access?
Most organizations require some form of Internet access to receive information, place orders and communicate with their customers. If your primary business network is not entirely internal to your company, you will still need network security between your local network and the Internet. If you have experience downloading, you can install and manage your own firewalls. Most SMBs will find it more cost effective to look at managed security in the cloud. WAN bandwidth providers that offer this option have the necessary in-house expertise and are available 24/7.
For emergencies only
I know. It is tempting to use this second network for commercial purposes if your primary network runs low or fails. Be very careful. In such emergency situations, you can disable or block the public Wi-Fi hotspot to prevent unauthorized access.
Do you need point-to-point WAN bandwidth, dedicated basic Internet access or dedicated point-of-contact bandwidth? What about managed security for your company? If so, find out what secure network solutions are available and right for the size of your business.
