are connected to wireless from the moment they leave their home till they get to work and then back. Wireless communication definitely provides an advantage over wired networks due to its mobility allowing users to connect from virtually anywhere, however because of this convenience they are also more physically exposed compared to wired networks because of how the data is transmitted given attackers a high number of access points to constantly attack. This also brings around the concern because of
Introduction Wireless networks have grown in popularity. This is largely due to the increase in the value of a network as more users are attached to it. The value added to a network by nature of connecting more devices to it, is summarized in 'Metcalf's law.' Metcalf's law states that if you 'connect any number, 'n,' of machines - whether computers, phones or even cars - and you get 'n' squared potential value.'[1] The incredible growth of the Internet seems to validate Metcalf's law. It then seems
for the increasingly numerous ¡§hot spots¡¨ where high-speed Internet¡¦s access is free. What I found interesting was that the hacks were pretty basic and that most of the information on how to break into default systems, how to look for Wired Equivalent Privacy (WEP) being enabled and other wireless steps could be found in a Google search. My brother Carlos a ¡§full time computer geek¡¨ and I had decided at the beginning of the summer that we were taking the family to Disney but I wasn¡¦t going
Wireless Communication Security Abstract In today’s society advances in technology are growing rapidly. Businesses and people are taking full advantage of the improving ways of transmitting data internally and externally. One of the mediums today in transmitting data is via wireless communication systems. It is obvious that this data will need to be secure for many reasons. These will be the questions I will pose in this paper. Will this be a secure means of transmitting data? How
The average consumer never thinks twice about using a credit card, when purchasing at a major chain department store. Most point of sales and credit card terminals, are made by a choice few companies. As a result this means that a hacker only needs to know how to exploit vulnerabilities from a small handful of systems. When a consumer makes a purchase they never wonder “is my transaction safe?” Never do they wonder if the company’s Information Technology department has upgraded all computer systems
This paper is going to discuss wireless security from a broad view where I will go into why exactly wireless security is so important especially today as the ways in which we are communicating is changing dramatically. From there I will discuss the multiple wireless securities that are available to give a better understanding of the options given. Then I will go into why exactly not protecting your wireless can be so dangerous with some descriptions on the most dangerous wireless attacks out there
III. Once Firewall protection has been verified, a good Antivirus program should be chosen according to the need of the company structure. Antivirus software is computer software used to prevent, detect and remove malicious computer viruses. Most Antivirus software also works against other types of malware, such browser hijackers, keyloggers, backdoors, rootkits, trojan horses, worms, malicious adware and spyware. There are numerous types of Antivirus protection software to choose from. Signature-based
A wireless network is a wireless communication system that allows electronic devices and computing workstations communicate and exchange data with each other by utilizing radio waves as the transmission medium. Wireless networking offers many advantages for organizations and users such as increased productivity, portability and flexibility, and lower installation costs. However, wireless networking is also coupled with security threats that can alter and damage an organization’s computing and networking
Outside of no mention of the physical location of the device in the synopsis, which is concerning, a simple review of the device indicates that the device is technologically obsolete. For instance, the NetGear WGR614 came initially with wired equivalent privacy (WEP) only, and did not receive an update to provide it Wi-Fi Protected Access 2 - Pre-Shared Key, until 2 years after its release (). While the use of this router may deter the most basic intrusion attempts from individuals searching for
alternative for, a wired Local Area Network (Kolawole, 2014). In wireless LAN transmission making use of radio frequency to communicate over the air eliminates or at least minimizes the use of physically wired networks. From the beginning, IEEE 802.11 was designed to look and feel like IEEE 802 wired networks to include supporting all of the protocols and LAN management tools that operate on a wired LAN (O 'Hara & Petrick, 2005). The major differences in a wireless LAN and a wired LAN is of course
a. What does the network layer do? What is interior routing and what is exterior routing? In the Open Systems interconnection Model (OSI Model), the network layer lies in the third level and for network communication it provides paths for data routing. It is considered as the backbone of the OSI model because for the purpose for the data transfer between nodes, network layer performs selection and management of the best logical path. Switches, firewalls, bridges and routers are some hardware devices
E-commerce: Security and Privacy As the evolution of the internet and purchasing online becomes popular, so do the security factors that contribute to the ways of eliminating fraud, theft, and acquiring personal information. E-commerce has created many new ways for customers to make payments including e-cash, e-cheques, and e-wallets. In the 21st century, many organizations worked hard at securing communications and payments made through e-commerce transactions. In doing so, customers would
in a business environment. For example if setting up a wireless based VoIP system you would need to make sure you’re using 802.11n or 802.11ac to ensure the bandwidth is able travel to reduce lag and jitter during the call. Also, when setting up a wired based system you will need to make sure you have a high-speed backbone to your network from the point of the switch managing the VoIP calls. This can be enabled by using gigabit links and also making sure you are using Cat 6 cabling to further reduce
a new age of online regulation, stating that the Internet has become so crucial that it needs a category similar to any other public utility so the government has more ability to regulate it (“A Plan to Treat Web”). This would make the internet equivalent to electricity or water, forcing consumers to pay for how much they use, and the speed at which they want the access. The necessary move to regulate internet plans to safeguard consumers and businesses from Internet Service providers trying to boost
Review of interconnection hardware – hubs, switches, routers Our design includes hubs, switches and routers in the infrastructure. In this section we will provide a quick overview of these appliances. Network hubs, switch, and router all perform the job of connecting computers. A network hub connects computers to each other, but it is designed with no real understanding of the information that is being transferred through the hub. what it is transferring. Network hubs are usually used in a private
Most Common Wireless Networking Access Methods Wireless communication has created an ever-evolving need for devices that are faster and applicable to a variety of lifestyle situations. As new devices are created, security measures have to be implemented and policies have to be adapted as the way we live changes in response to the technology available to us. Two of the most common wireless communication access methods are Bluetooth and WiFi. Bluetooth technology creates personal area connections
Bitcoin the Cryptocurrency: Stimulating Global Economic Growth Bitcoin is a form of digital currency that is similar to physical cash stored in a digital form. It is the first fully implemented cryptocurrency protocol utilizing an open source peer-to-peer payment system. As a transfer protocol, it fundamentally functions as a money transfer medium that sends bitcoins from user to user without the need of a third-party intermediary and the system is protected by peer-reviewed cryptographic algorithms
