Discussion Topic

In today’s communication, no network can be considered fully secured either it is wired or wireless. Theoretically, it is possible to break the security of any network. In your opinion, among wired and wireless networks, which network creates more security problems to cater? Justify your answer in either case with three proper reasons.

i don't think so wireless is best choice because wireless creates more security problem than wired. A wired networks are connected by physically plugging in a cable from one device to another, it is much more difficult to access them without authorization. There is no opportunity for someone wandering past your office windows to hack into your wireless network, for example. There's no need to give out wireless access keys -- a device physically connected to the network is part of it. If you want to keep your network as closed and secure as possible, then a wired network is the way to go.

M.Tariq Malik bhai we are also agreed that wired is good choice for networking but in GDB Question sir ask the network which create more problems and reason..so the Danish bro is also right  

Wireless Networks vs. Wired: Which Network is More Secure?

Wireless networks are rapidly becoming the popular standard in home networking. Not only do they allow you to access the Internet from anywhere in your home, they make web surfing and file sharing incredibly convenient — and can eliminate cable clutter by eliminating the cables themselves.That’s particularly valuable when you consider that today’s networks might include other devices such as game consoles, music systems, and even telephony. Where are you going to hide -- not to mention hook up -- all those Ethernet cables? For families with children making their presence (virtual and otherwise) felt, all the cables were just an eye soar stretching from room to room. But there are times when wired networks make sense. Let’s say that you live in a house that was pre-wired with Ethernet cable, with a port in every room. That’s not uncommon in many homes built during our latest housing boom. In that case, the simplicity and security of a wired home work in your favor. You just need a router to ensure that you can all share access to printers, file servers and the Internet…and a simple way to set up, visualize and manage the network.Don’t get us wrong. Advances in wireless technology mean they are just as secure as wired networks -- as long as you set them up properly. Theoretically, anyway, it is harder to hack into a wired network than a wireless one that has not been set up with proper encryption, password protection and MAC addressing.Both wired and wireless networks require routers to share files, resources and a single Internet connection. If you use WPA encryption, strong passwords and MAC addressing on your wireless network, there is virtually no difference in security; both are equally impervious to attacks. However, many users who are concerned about the security of the network completely undermine their own security by not taking the proper steps, or for doing something that no software or infrastructure could ever prevent: falling for social engineering scams that result in users themselves providing their own credit card numbers, social security numbers or passwords to a seemingly legitimate (but bogus) email.How can you be sure that your network -- wired or wireless -- is secure? One way is by using a home network management program like Network Magic. It helps you set up, configure, secure and manage your home network without endless calls to help lines or scratching your head over confusing exec-file language. The same intuitive wizards will walk you through these easy steps on either type of network.It seems clear that wireless networks are the wave of the future. But whichever type of network you use in your home, securing it is key.

Benefits of wireless connection
While a physical infrastructure may be good from a management point of view and offer cheap deployment, having all those wires running throughout a building can be costly and awkward to maintain. For example, if a business increases its workforce, all those new workers will need physical connections at their desk – connections that will need to be manually set up. Any breakages in the wired connection will also have to be manually fixed as there is no software solution to a broken Ethernet pin.

With the explosion in mobile devices over the last few years – Apple alone has sold around 100 million iPads since the tablet was introduced in 2010 – many workers are bringing their own devices into the office. It is vital these employees have access to the corporate network to get the most out of them, and that means giving them wireless access. As well as being able to use their own devices, wireless infrastructure means freedom to move around the office, from desk to desk or meeting room to meeting room.

A wireless network is also neater, getting rid of all those unsightly cables that usually run around an office.

wireless specially WiFi provide best security

In terms of how wireless network security compares to that of a wired network, theoretically Wi-Fi should be just as secure as a wired connection, but that's what security experts thought five years ago when WEP was the prevalent wireless encryption protocol, and it of course turned out to be relatively easy for skilled hackers to bypass. The bottom line is that radio communications are likely always going to be more susceptible to eavesdropping than wired communications, so enterprises should account for that risk and plan their network architectures accordingly.

Disadvantages – For a given networking situation, wireless LANs may not be desirable for a number of reasons. Most of these have to do with the inherent limitations of the technology.

  • Security – To combat this consideration, wireless networks may choose to utilize some of the various encryption technologies available. Some of the more commonly utilized encryption methods, however, are known to have weaknesses that a dedicated adversary can compromise.
  • Range – The typical range of a common 802.11g network with standard equipment is on the order of tens of meters. While sufficient for a typical home, it will be insufficient in a larger structure. To obtain additional range, repeaters or additional access points will have to be purchased. Costs for these items can add up quickly.
  • Reliability – Like any radio frequency transmission, wireless networking signals are subject to a wide variety of interference, as well as complex propagation effects that are beyond the control of the network administrator.
  • Speed –  The speed on most wireless networks (typically 1-54 Mbps) is far slower than even the slowest common wired networks (100Mbps up to several Gbps). However, in specialized environments, the throughput of a wired network might be necessary.
