This paper will also discuss several methods to mitigate and protect a wireless network against security attacks.
Introduction
The expansion of wireless networks has abundantly increased in corporate and home environments in the last decade. Wireless networking cards have been installed on many devices such as laptops, tablets, smartphones, and even kitchen’s devices. Wireless network technology offers many advantages because of the increased accessibility of information resources. The popularity of wireless networks is primarily due to their convenience, cost efficiency, and ease of integration with network components. Even though wireless networking technology has many benefits, it also has its share of disadvantages. When new cyber-attacks are created they can potentially threaten the security of a wireless network. As the deployment of wireless networking increases, security loopholes have presented cyber hackers with many opportunities. The issues that wireless networks presents to network managers include unauthorized access, broadcasted service set identifiers (SSIDs), unknown stations, and spoofed media access
Segmenting the wireless network from the wired network though, is not only a trust issue, wireless networks suffer from many attacks such as Denial of Service caused by interference. The access point that will provide wireless access will be connected to a wired switch, however the separation of the wireless network is proposed to be done with the use of virtual LANs. VLANs will separate the network to two logical networks operating on the same physical network. This separation will enchant network’s security as the main network will be inaccessible from customers as well as it will not be affected if the wireless network is facing issues. The AP must be using Wi-Fi Protected Access 2 (WPA2) security protocol that has advanced encryption standards comparing to

Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia area and using a Local Area Network (LAN).
Wi-Fi facilitates ease of use and is getting increasingly popular with homes and businesses. Multiple Wi-Fi Access Points can be located in a given area. Wi-Fi security issues continue to be a problem, as the number of Access Points grows.
This proposal is for a small office that will have users who are connected by Wi-Fi or cable. The network will include devices and resources that is shared among all the users. The network will need to have security measures in place to protect the entire network and keep the wireless access secure and available only to employees of the company.
There are numerous network security devices and tools available to aid in computer network defense, and these tools are often relied upon for protecting against increasingly sophisticated, stealthy, and damaging attacks. When acting alone, the current generation of security devices has an exceedingly difficult time providing an effective defense against such threats, and the situation is particularly grim for targeted or novel attacks.
While the conventional desktop PC will still continue to serve important functions at both consumer and professional levels, there is an expectation that mobile devices will become the predominant form for accessing both personal and professional content; it is understandable that cyber criminals have begun focusing on mobile devices which have at the same time grown their user base while substantially consolidating the operating system variants which makes the surface area for a potential attack substantially larger (Juniper Networks, n.d.).... ... middle of paper ... ...

Recent advances in wireless technology provide the security of blocking the attackers and also need to eliminate the attackers in the network. But in this paper providing the new technique to handle the attacker using an duplicated data as an backbone and also using dynamic key management in this system to providing the more security of the data’s in the wireless sensor network (WSN). So attackers are get confused to finds the original data’s. They don’t know the original data’s are safely send to the base station.
The world has gone through a lot of changed as time passes by. With advancements in the technological field people are can communicate with ones from around the world without having to even lift a finger. To make things more efficient and more cost saving industries have made technology wireless. Wireless technology gives people the chance to get up from their stationary computer, or cord phone and able to freely move without restrictions. The IT, or Information Technology has become a standard and very critical part of today’s society. Wireless technology came from the basic just cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with forever revitalizing technology.
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
G in 1G, 2G, 3G and 4G stands for the “Generation” of the mobile network. Today, mobile operators have started offering 4G services a higher number before the ‘G’ means more power to send out and receive more information and therefore the ability to achieve a higher efficiency through the wireless network. During the time of 1G, radio signals were transmitted in ‘Analogue’ form. 2G networks on the other hand, were based on narrow band digital networks. The 3rd generation of mobile networks has become popular and users access the Internet over devices like mobiles and tablets. This means a 3G network actually allows for more data transmission and therefore the network enables voice and video calling, file transmission, internet surfing, online TV, view high definition videos, play games and much more. 4th Generation mobile networks are believed to provide many value added features.
In Nigeria today, scholarships are becoming a great way to get free money for university degree. But most of the time, students appear to have a little knowledge about how they can get the scholarship. Students believe scholarships can only be given to meritorious students. Internet has proved to be a great source of finding a variety of scholarships. There are scholarships for all kinds of student.

. The company lacked working synergy, as workers did not know one another. As a result, Meyer was looking forward to promote synergy in the organization and make workers feel part of the organization. The company had various idle infrastructures. As a result, Mayer saw the opportunity to bring workers together as a means of doing away with laziness, and utilizing idle infrastructure (Carlson 2).
