Security Measures in Wired and Wireless Networks

Security Measures in Wired and Wireless Networks 

The purpose of analysing this journal article is to learn more about the security plans that we must take on board in order to protect our wireless network. Because of the nature of wireless fidelity (Wi-Fi) technology which by rule the data is not travelling via a wired network our networks are exposed to the public space and our job is to secure them. This article introduces many security measures and make very clear the way to use the encryption technology that our wireless devices come with to protect our data.

The existing protocols are the wired equivalent privacy protocol (WEP) and the wireless fidelity (WiFi) Protected Access Protocols (WPA or WPA2). By describing those two security protocols the article explain the reasons that even though it is a secure method to protect your files by ordinary people who try to grand  access to your network, it is not the most efficient way to protect your WLAN by hackers. The WPA and WPA2 protocol is the most secure method at the moment. it offers a longer key which takes longer to decipher but still even this type of encryption is not 100% secure. By doing experiments for the security of wireless systems and simulations in different protocols the article with the help of tables and figures shows some of the reasons that the “threat” is always one step ahead of the defence mechanisms.

Personal impressions:

This article made me to be aware of the security that we have available for our wireless networks. Also it helped me to form my personal opinion according to issues have been addressed from  this article and. By taking on board everything that have been said so far I think that a big security hole is the lack of stronger encryption and the updated wireless devices in a network.That makes it the main problem of  personal and business networks and because of that they are  vulnerable from unauthorised users.  It is a fact that human computer interface designers plays a big role on that specific issue as they raise barriers in the security mechanisms. As a result the daily end user has a limited variety of options which comes mostly from the security programs that computer interface designers has to offer in form of a software of hardware product solution in exchange of customer’s expenses.

Three potential topics for the main project

Below I will name three of the topics that interest me and I will explain the reasons. All three of them are very nice to pick for my project and in this post is why.

Network Security

Network security is a very interesting field that and a very important one. Computers are all about safety from physical or cuber thread. Security is there to protect your personal information and to ensure your safety on the network. It is classified one of the most important things nowadays. Companies and even individual are spend a lot of money for security.

Why networking security is interesting?

Networking security is very popular and so interesting because it covers a lot of fields in the around computing. It’s very interesting and educating in the same time to learn how to protect yourself against general threads and how you can improve your security level of your network.

Wireless networks

Wireless networks are very common nowadays. They connect the computers together for different kind of purposes like exchanging files, connecting them with the internet and communication. In a general sense, wireless networks offer a vast variety of uses by both business and home users.

Why am I interesting on Wireless networks?

Wireless technologies became a big part of our life and without them we would be not able to develop and share new things. It is a challenge to understand how they work and how you can take advantage of them and use them on 100 percent of their capability.

Artificial intelligence

Artificial intelligence (AI) is the intelligence exhibited by machines or software. This technology became very popular the last decade by doing big progress on producing machines which they can interact with the people. Many scientists warn us about the negative from those projects and the technology in general. They claim that in a few years humanity will be overwhelmed by artificial intelligence machines that they will be able to think and act on their own.

Why   artificial intelligence is interesting me?

It is very mysterious on how you can learn by programming a machine to do, to say or even to predict things. This is a very interesting project that teach you about those machines and the way they interact with people. By study that technology is like you have a powerful weapon in your hands but its up to you the way that you will use it.

Wireless Network Security

According to the article of national Institute of standards and security there are many protocols and security parameters of them that you should follow. All of them though have their own faults and holes which gives the hackers the chance to exploit and hack into the system through wireless networks. The article introduce some software and even hardware solutions to resolve this problem by making the system more secure and more reliable. The wireless systems are not safe and also they are not made without faults.  The danger is on high risk and the developers trying to patch the holes that leave the systems exposed. The article also is talking about the nature of the wireless systems and protocols and how they apply to become a functional communication network.

My personal impression of that article.

I think that this article help me understand more in depth the importance of the wireless systems and its structure. Also it answered many of my questions and equerries that I had and helped me to understand the matter of security according to the wireless networks.

Introduction

Hi my name is Kostas, i’m 20 and i am currently studding Computing in the university of Bolton and i’m originally from Greece. Since I was young I was very good with computers. My passion in the field of computing was the networking and security because it was something I could understand and i was happy to do it and also I always wanted to know more about how computer networks work and how we interact with them, that was fascinating for me, and that was the reason I choose to follow this path of becoming a Networking engineer.
