I] INTRODUCTION
With the advancement of mobile technology, wireless networks have become widely available and interconnected. For allowing people to get connected seamlessly using their mobile devices without being limited by the geographical coverage of their own home networks, roaming services have been deployed, for example, GSM [9], [17], 3GPP [20], and WLANs With the advancements in various mobile and wireless networks, e.g., long-term evolution (LTE) [1] worldwide interoperability for microwave access (WiMAX) [3], and roadside-to-vehicle communication systems [2], pervasive Internet access becomes a reality, enabling mobile subscribers (MSs) to enjoy Internet
In the pursuit of opening a great venture with my business partner we are hoping to
Wireless networks have become a major part in the operation of businesses and in people’s lives. Wireless networks can provide fast speed internet connections without having to use wired connections. Businesses are doing much better with wireless networks because they don’t have to pay the costs of installing wired networks and people can work easier because they do not have wires running all over the place. Now with wireless networks in place, businesses are able to connect to their other branches and buildings within their area as well.
The concepts of wireless network security consist of commitment of cyber security and maintaining security based on the latest development and exploits against the network K.W. Ross, J. K. (2012). Wireless Network Security is based on the principles of cryptography, message integrity, authentication, securing e-mails, securing TCP connections: SSL, securing Network layer: IPsec, securing wirelsess: LANs, securing the operational security structure, such as the firewalls and the IDS K.W. Ross, J. K. (2012). This security

Wireless is the term used to describe any computer network where there is no physical wired connection between sender and receiver, but rather the network is connected by radio waves and or microwaves to maintain communications (Boyds, 2016). Wireless and mobile technologies continue to have a major impact on the global business environment and can be roughly categorized into mobile client devices for interactivity and communications infrastructure. Wireless technology is technology that uses radio waves to transmit and receive data, such as cell phones. It is used more than ever today for data transmission. Mobile
In the past thirty years computer technology has been developing very rapidly. Internet in last decade has revolutionized the way how we conduct our lives and businesses. Internet has become a daily necessity we cannot live without. Development of Internet and wireless technologies together with advancement in miniature technology has made it possible for us to have access the internet on the go. Every year we expect new and more advance models of smart phones, or new more sophisticated window systems, or new and more reliable internet security program in hope that this time advancements in technologies not only help to improve our life, but help to protect our privacy while using the
Our society is becoming more and more reliant on wireless connections. The ability for both employees and consumers to connect wirelessly is a must in this day and age for businesses. Because of this, strict security policies must be put in place in order to keep the business and its data secure. This paper will discuss the pros and cons of wireless connections, the need for authentication and six top threats that companies should be aware of and how to prevent them.
Systems today require great security; however WLANS have some special security necessities. This segment looks at some of the security requirements for WLANS and security alternatives. WLANs are prone to various vulnerabilities that don 't exist for wired Ethernet LANs. Such vulnerabilities provide hackers unauthorized access to network. Different vulnerabilities may be brought about by a well intentioned however clueless worker who introduces an AP without the IT division 's endorsement, with no security. This would permit anybody to get access to whatever remains of the Enterprise 's network.
Issue Overview Wireless devices, like all technological devices that provide external type access to networks, have special security challenges. Mobile devices and wireless networks rely on a rather broad spectrum of technologies. If one relies on industry standard protocols like TCP/IP, HTTP, SMTP and TAP there are numerous options for enhanced network security. Attacks or vulnerabilities are often based on the operating system of the device or platform being used. Information can "leak" to other networks, Malware can compromise the network, move across platforms, and of course, in some cases, individuals can try to hack in and compromise data (Becher, et.al., 2011).
Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking
Wi-Fi can be found anywhere in this day in age, you can walk into almost any establishment and you’ll be sure to find their Wi-Fi, accessible from anywhere within their spaces. Each data packet being transmitted through the air, whether containing private, sensitive or insensitive information, is available for an attacker to capture. To fight against this, there have been some standards that have come out through the years to guard and protect data, such as WPA. All standards have been created to replace the preceding one due to vulnerabilities found in the engineering of them. Still to this day, not every standard is fully secure, attackers still find
Thesis; Along with the efficiency mobile devices render, come along its risks, in which raises substantial security and privacy concerns. It’s important to be aware of the possible threats a mobile can have, along with knowing what and how to secure information, as well as trying to prevent threats from happening.
Wireless networks are offered by many restaurants , hotels , cafes and other public places to their customers , but connecting to such a free wireless network might cause your device some issues regarding to security , if possible reduce the use of such networks [6] .
There are many reasons why wireless networks are used. One reason is for a temporary backup to an
Abstract: Wireless sensor networks is growing rapidly from the past few decades. Due to its scalability, wireless sensor networks is used in many applications. Among various wireless networks, Mobile Ad hoc networks has been one of the unique network. Unlike other network architectures, MANETs have no central architecture; every node is free to work both as a transmitter and receiver. Every single node can communicate freely with every other node which is in their communication range. Otherwise, it depends on neighboring nodes to relay messages. Due to this nature, MANETs are used in many missionary applications like military use and emergency recovery. However the wide distribution of MANETs makes it
