Your sensitive information is always on the move, and it is important to assess the goals of your wired and wireless security solutions.

Having the right connection to the Internet can be a crucial consideration for your business since both wireless and ethernet connections have advantages and disadvantages. Both of these connection technologies have their own specific levels of security, and both can provide a stable environment for your company. In choosing which one is better to implement for your particular circumstances, you should consider the advantages and disadvantages wired versus wireless security described below, before going one way or the other.

Ethernet Connections

Ethernet connections are characterized by the cables which connect them to switches and routers in your network, and they allow for local area network access by all your employees. One of the advantages provided by ethernet connections is that they are recognizably faster than wireless connections because cables are less prone to any kind of interference.

If yours is a business which routinely deals with high volumes of data transmission, or if that data is deemed to be extremely critical, an Ethernet connection may be the better choice for you. Ethernet is also very reliable, or at least as reliable as all the hardware components in the network, and the Internet provider whom you are associated with.

One of the disadvantages of Ethernet is that it relies on cabling, which must be implemented all throughout your office environment in order to reach and connect every workstation which needs access. Every one of these cables must somehow reach the server room, where the Internet connection is. Needless to say, making these kinds of cabling runs can be fairly expensive, and if there are ever any kind of changes which need to be implemented, there can be another heavy expense in a re-cabling, or adding cables to the existing wiring runs.

Another downside posed by the huge physical presence of cabling is that there’s a possibility that they pose a safety threat to employees, especially when there are any cables situated within high traffic areas, or in locations where cables are not well secured, and away from common pathways.

Wireless Internet Connections

With regards to wireless security, a new set of considerations must be made. When using wireless Internet connections, the switches and routers are used to broadcast data signals, rather than using the cable connections in an Ethernet environment. Any employees needing access to the network must have approved credentials and must have authorized access to the network.

One of the great advantages of wireless connections is that they offer more flexibility than ethernet connections do. Computers in a wireless environment need not be slaved to cables, which means they can literally be taken anywhere in the company building, where the signal can still be sent and received.

Since there’s no physical connection requirement, all your mobile devices can be used to connect to the Internet in locations where a Wi-Fi signal is in effect. This, in turn, generates a great many opportunities for conducting business in the modern business environment. One of the big examples of this is the Internet of things, where literally millions or billions of devices around the globe can all be connected to the Internet without the use of any cabling, so that backend analysis and recommendations can be forwarded to the connected devices for self-improvement.

It might take more upfront time to implement a wireless network, but once it has been set up, it’s much quicker to achieve your business objectives wherever you might happen to be. This means that you can send emails while you’re on the road, rather than needing to get back to the office to access your workstation, connected to the network.

In a factory environment, decisions can be made much more quickly, because mobile access is possible from wherever a device owner happens to be, rather than having to get back to an office and get connected.

One of the downsides to wireless connections is that they are not completely reliable in all settings. They are more subject to background noise and interference, and they can experience interruptions by large buildings or other objects, which interfere with the line of sight.

This means that it may not be a good idea to implement wireless connections when your company routinely transmits large volumes of data, or when it transmits extremely sensitive data to other locations. It should be noted that these kinds of disruptions are not frequent and that they certainly don’t detract from the reliability of wireless connections, but as compared to ethernet connections, they do occur more frequently.

Wireless security concerns differ from those present in an Ethernet environment, as the signal strength and access potential are not the same.

Wireless Security Versus Wired Ethernet Security

In terms of security for the Internet, wireless connections would have to be considered slightly less secure, even though there are a great many actions which can be implemented which will improve wireless security, and make it more robust against potential cyber-attacks.

There is also a greater possibility of users being exploited when connecting to Wi-Fi networks because they might take their laptops to hotspots in cafés or other public places, where there would be a potential for data hijacking by cyber attackers.

This, of course, could be counteracted by not allowing company laptops outside the building, but that would restrict the productivity of employees who might want to work at home, or of those who need the mobility of being able to work on the go, for instance when visiting clients.

Ethernet is simply the more secure option because data which is transmitted over cables cannot be intercepted or hijacked as easily as it can be in a wireless environment. While Ethernet is not entirely secure, e.g. phishing attacks can still be made against off-guard employees, it must be regarded as the more secure of the two connection options when compared to the factors pertaining to wireless security.
