The Security Issues Revolving Around Wireless Networks

Wireless security in 802.11 is less robust and has many security flaws that can be exploited by an attacker. Security best practice for wireless networks depends on a defense in depth strategy, with five control layers:

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

Wireless attacks have becoming a more common security issue when it comes to networks. Attacks can get a lot of information that is being sent across a network and use to commit crimes in other networks. Every wireless network is vulnerable to attacks and it is the important that all the necessary security measures are taken so as to prevent the mess these attacks can cause. These attacks are normally carried out to target information that is being shared through the networks. It is therefore very important to know of such attacks so you will be able to identify the attack when it happens.

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

The various papers on the recent explorations and growth in the field of Wireless Sensor Networks and attacks in WSN’s have been reviewed and discussed below:

Abstract -This paper addresses the internal and the external security challenges in organizations that implements wireless networks. Distributed security is designed to provide a more secure data communication among faculty members, staff and students. A description of the technique used to protect and keep PC 's up and running is illustrated with applications.

Many people know that curiosity killed the cat, for hacker’s curiosity is deep in their roots. It started with the word hack. “Hack” was used as a term witch is to improve performance of programs. Pagllery stated that “Hacking became the art of figuring out unique solutions.” and that “hackers wanted to make technology work better….” In the 1970s hackers used a whistle tone for free international phone calls. In the 1980s, instead of teenage hacking the phone network system, hackers began to attack computers for money and espionage (Pagllery). This brings in the DHS (Department of Homeland Security) to combat terrorism, but later to also combat the growing cyberterrorism. The DHS was created after the 2001 terrorist attack on the world trade

Wireless connectivity is critical to most homes and corporations as the world advances in technology. The technology has grown to a capacity that allows for extreme growth in wireless infrastructure as well as a trend of bringing your own technology device. Many corporations experience a high volume of critically important information being transferred over it wireless network so security is essential. There are many differences between a home and corporate wireless installation and each has its differences in securing.

Confidentiality: It prevents the access to the data for unauthorized users or nodes when two authorized nodes are communicating .Since MANETs use the open medium, all users present within the transmission range will have access to the data. The data can be kept confidentially by performing encryption on it.

The café latte attack relies on a user’s laptop being connected to a Wired Equivalent Privacy (WEP) protected network and tricks the user into sending thousands of WEP-encrypted ARP (Address Resolution Protocol) requests. An ARP is a network protocol that maps together a network layer address and a data link layer hardware address. For example, an ARP is used to resolve IP addresses to their corresponding Ethernet address (Leyden, 2007). For a café latte attack to be successful, the cyber-criminal does not have to be in the same area as the user but can also be in a remote location to intercept the WEP key. A cyber-criminal can take advantage of the message modification flaws in the 802.1WEP architecture and the shared key authentication by flooding a network with encrypted Address Resolution Protocol (ARP) requests. A café latte attack functions by using a bit-flipping technique that modifies the Media Access Control (MAC) address and Internet Protocol address (IP address) of a user’s computer which is collected when gratuitous ARP requests are sent from the cyber-criminal. When the user responds to the gratuitous ARP requests, the cyber-criminal can quickly crack the WEP key from the user’s traffic. With a café latte attack, a cyber-criminal can obtain the WEP key in less

Hacking is a relatively new technique to describe gaining unauthorized access to a network or computing device. A negative connotation has always been associated with the term. However, in order to catch hackers law enforcement will often reverse engineer the same methods that they use. Hacking has proven to become a major challenge for law enforcement. Device and network intrusions are not easily accomplished. The skills needed to perform a hack requires a succinct knowledge of computers and networking which can take years to fully understand. Society tends to ignore the intricacies of computers and often leave themselves exposed to potential invasions. Since a majority of the public are unaware of protecting themselves, illegal hackers can thrive knowing most people are possible targets.

Within this article, the authors states that in order to provide a safe and secure wireless network, they outlined the counter attacks and measures for the security of wireless networks. Some of the counter attacks that the authors have listed includes, system security - which breakdowns to administrative level security, physical level security, and technical level security, and information security (Ameen et al, 2012). For the purpose of answering the previous question, the main counter attack that would best defend against the problems would be system security - particularly the administrative level security. At this level of security, administrative control over the system by establishing a well defined user hierarchy plus a strong authentication measures, can prevent security breaches of WLANs from

Computer hacking: Is the practice of modifying computer hardware and software to accomplish a goal outside of the creator’s original purpose. People who engage in computer hacking activities are often called hackers. Since the word “hack” has long been used to describe someone who is incompetent at his/her profession, some hackers claim this term is offensive and fails to give appropriate recognition to their skills. The majority of hackers are technology buffs. They are self-motivated and learning about computers is their true passion. ("What Is Computer Hacking?" WiseGEEK. N.p., n.d. Web. 27 July 2013).

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.

Hacking is the process of gaining unauthorized access to information through various means like systems or computers. In the context of computer security, a hacker is that person who looks for weakness in a system so that they can gain access to unauthorized information. They are motivated by various reasons like protest, profits or evaluating the entire system weaknesses.
