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.

Many employees in our enterprise handle sensitive data on a daily basis, so having secure network connections is of the utmost importance. Up until now, we've only used Ethernet-based network connections, but there has been increasing pressure from business managers to install wireless. Can a state-of-the-art Wi-Fi connection really be as secure as an Ethernet connection, or would sending so much sensitive data over a wireless network be asking for trouble

D_Asif now lets start with me...

I think its wired not wirless.. I am 10000000000% sure i have work with army. One of the Major who was mine friend at near the border of Indian Occupied Kashmir. He said "Wire is best as compared to wireless" and i said when you use wireless he said if there is problem and our system fail then army use at last option wirless because in air some one catch your frequency and its easy to decript the information but in wire possiblites is lesster then then the wirless

yup sure ...

really you work with army great it's just awesome 

you are +infinity % true wired networks are best 

but little think about WiFi

Computer networks for the home and small business can be built using either wired or wireless technology. Wired Ethernet has been the traditional choice in homes, but Wi-Fi wireless technologies are gaining ground fast. Both wired and wireless can claim advantages over the other; both represent viable options for home and other local area networks (LANs).
Below we compare wired and wireless networking in five key areas:

ease of installation
total cost
reliability
performance
security
About Wired LANs

Wired LANs use Ethernet cables and network adapters. Although two computers can be directly wired to each other using an Ethernet crossover cable, wired LANs generally also require central devices like hubs, switches, or routers to accommodate more computers.
For dial-up connections to the Internet, the computer hosting the modem must run Internet Connection Sharing or similar software to share the connection with all other computers on the LAN. Broadband routers allow easier sharing of cable modem or DSL Internet connections, plus they often include built-in firewall support.

Installation

Ethernet cables must be run from each computer to another computer or to the central device. It can be time-consuming and difficult to run cables under the floor or through walls, especially when computers sit in different rooms. Some newer homes are pre-wired with CAT5 cable, greatly simplifying the cabling process and minimizing unsightly cable runs.
The correct cabling configuration for a wired LAN varies depending on the mix of devices, the type of Internet connection, and whether internal or external modems are used. However, none of these options pose any more difficulty than, for example, wiring a home theater system.

After hardware installation, the remaining steps in configuring either wired or wireless LANs do not differ much. Both rely on standard Internet Protocol and network operating system configuration options. Laptops and other portable devices often enjoy greater mobility in wireless home network installations (at least for as long as their batteries allow).

Cost

Ethernet cables, hubs and switches are very inexpensive. Some connection sharing software packages, like ICS, are free; some cost a nominal fee. Broadband routers cost more, but these are optional components of a wired LAN, and their higher cost is offset by the benefit of easier installation and built-in security features.
Reliability

Ethernet cables, hubs and switches are extremely reliable, mainly because manufacturers have been continually improving Ethernet technology over several decades. Loose cables likely remain the single most common and annoying source of failure in a wired network. When installing a wired LAN or moving any of the components later, be sure to carefully check the cable connections.
Broadband routers have also suffered from some reliability problems in the past. Unlike other Ethernet gear, these products are relatively new, multi-function devices. Broadband routers have matured over the past several years and their reliability has improved greatly.

Performance

Wired LANs offer superior performance. Traditional Ethernet connections offer only 10 Mbps bandwidth, but 100 Mbps Fast Ethernet technology costs little more and is readily available. Although 100 Mbps represents a theoretical maximum performance never really achieved in practice, Fast Ethernet should be sufficient for home file sharing, gaming, and high-speed Internet access for many years into the future.
Wired LANs utilizing hubs can suffer performance slowdown if computers heavily utilize the network simultaneously. Use Ethernet switches instead of hubs to avoid this problem; a switch costs little more than a hub.

Security

For any wired LAN connected to the Internet, firewalls are the primary security consideration. Wired Ethernet hubs and switches do not support firewalls. However, firewall software products like ZoneAlarm can be installed on the computers themselves. Broadband routers offer equivalent firewall capability built into the device, configurable through its own software.

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.If you have any immediate questions, feel free to ask us in the comment section below. We’re also on Facebook and Twitter.
