...Evil Twin Wi-Fi Attacks NT1110: Computer Structure and Logic October 23, 2013 Abstract What is the “Evil Twin”? Evil Twin is a type of Wi-Fi attack, it is a home-made wireless access point that masquerades as a legitimate hot spot with a very strong signal in efforts to gather personal or corporate information. With this, the overall goal of this report is to educate the public on how to protect themselves. Additionally in this disadvantages and advantages will be discussed along with the effects on consumers and the future. According to Dr. Phil Nobles, a wireless Internet and cybercrime expert at Cranfield University, said: this is how the evil twin works. "So-called 'evil twin' hotspots present a hidden danger for Web users. In essence, users think they've logged on to a wireless hotspot connection when in fact they've been tricked to connect to the attacker's unauthorized base station. The latter jams the connection to a legitimate base station by sending a stronger signal within close proximity to the wireless client -- thereby turning itself into an 'evil twin. Cybercriminals don't have to be that clever to carry out such an attack. Because wireless networks are based on radio signals they can be easily detected by unauthorized users tuning into the same frequency."

...data is very easy. Princeton did a study of low level tech hackers can access the most well protected computer (Roberton, 2008). The most popular tools the hackers use are Back door remote administrative programs and Denial of Service (DoS) Back door remote works through an uploaded exe file on a website that seems to be trusted. This software is usually spread between pcs. The infected pc communicates with someone via email at a work computer. The infected pc infects the work pc and the virus spread. This is similar to the situation at JP Morgan Chase. The hackers where able to get through via an employee. The FBI is involved because as the writers says the attempted hacking should have stopped but they believe other holes in the system were left unprotected (Goldstein, 2014). The type of breach at Chase was a simple backdoor process which gained the hacker’s access to approximately 90 servers. The breach was discovered but it also uncovered a vulnerability in the infrastructure of a large bank that has challenges protecting their servers on a day to day basis (Krebs, 2014) Denial of Service causes your pc to crash or become busy processing useless data, it ignores the breach going on. This is what happened with Home Depot and Target. The Malware was...

...Office (SOHO) network set up is a simple task when using “Off The Shelf” equipment and the default configuration. Sadly it is not as secure as one would like. Using the default configuration leaves the network open to would be hackers, hijackers and the next door neighbor looking to get some free internet. Today we are going to discuss the equipment used to build our SOHO and then how to step outside of the box and ensuring that we are secure. Our small businesses has a total of 5 employees working out of a converted basement. We use Verizon FIOS for our ISP using a Actiontec Wireless Broadband Router (GigE), 5 laptops, 1 PC and 1 wireless printer. . Router The backbone of our SOHO network is the Actiontec Wireless Broadband Router (GigE) model number MI424WR (GigE). Out of the box it "support very high speed Internet service." with "speeds up to 1000 Mbps wired (with the Gigabit Ethernet interface) and 300 Mbps wireless” using a 802.11b/g/n chipset. It comes prebuilt with an Enterprise level security including; customizable firewall, stateful packet inspection, Denial of Service (DoS) protection, content filtering, intrusion detection, WPA and WEP WIFI encryption. . Physical Network Configuration Our SOHO networks physical layout is pretty standard. Outside of the building is the Fiber Optic line that feeds into the Optical Network Terminal (ONT) for the building. From there a coaxial cable runs to the Actiontec Wireless Broadband Router (GigE). The 1 PC is “wired” to the...

...Phase 1: Identifying Requirements, Putting the Network Together Scenario NuggetLabs Industries is growing significantly. Due to space limitations, five employees currently share single cubicles…at the same time. While this is great for team building, these space limitations are now impacting business productivity. NuggetLabs has now leased an additional office building roughly 20Km from their headquarters location. While this office will eventually connect to the HQ office, it will initially be set up independently. NuggetLabs Industries has heard rumors of your ninja-like network consultation skills and has agreed to pay you an excessive amount of money to design and build their network infrastructure. Gathering Information To help guide this initial configuration, you‘ve assembled a list of requirements based on various meetings with management. * The new office will initially house 75 employees, each with their own Cisco IP Phone and PC. This office may eventually scale to 200 employees over 5 years. * The Windows admins are planning to install a new pair of redundant servers at the new office. They plan to manage all the IP addresses for DHCP on these servers and are waiting for you to tell them what IP address range they should use. * Windows admins: Jeff Service - (602) 555-1293, Mike Pack (480) 555-9382. * The new office is a two story building with the Main Distribution Frame (MDF) in the northwest corner of the first floor.

...Table of Contents Executive Summary 3 Introduction 4 Research Findings 5 Apple iPad 5 Toshiba Excite™ 13 6 Samsung Galaxy Note II 6 Recommendations 7 Conclusion 7 References 8 Executive Summary For a large company, with a large sales department, with many remote employees, three different technologies that have emerged within the last five years were looked at to compare features, usability, and size. I also looked at was how easy or difficult each device would be to set up, as well as how secure each device would be for employees to use. The devices were compared to find which device would be best to have each employee use. The Apple iPad is practical for small businesses because it can be set up for fewer users and it easy to use, as well as compact, which makes it easy to transport form office to office or from home to home for remote employees. Unfortunately, for large companies, the Apple iPad can be difficult to set up for multiple users on a single iPad. Setting up devices for each work station can be very costly, as it requires its own hardware for each workstation. The iPad runs faster with the A6X chip, which launches the applications faster and makes the device run faster. The device can support a wide range of virtual private networks, which makes the device secure. The Toshiba Excite 13 Tablet is a little bigger than the iPad, which can make it harder to transport, but easier to use when at home or in the office. It is about the size of a...

...more flexibility, than share memory sticks/floppy drives. You can share many different files ie photos, music, documents • Printer Sharing- Once is connected to the networks, you can easily set up all of the computers to share one printer. This save a lot of money, because instead of buying a printer per one pc, you can have one printer for each pc. • Internet connection sharing- It saves a lot of money with costs of speed internet. Many users can connect to the one network- which means you don’t have to pay twice or even more for the internet. However you may notice, that the Internet connection slows down, when there are many people that share the network at the same time. In Summary, you can store any kind of information at the network at one PC, and then you can retrieve it from different pc, that is connected to this network. Network Topology: The best network topology for small business in nowadays is star topology. The star topology looks like this : I would strongly recommend you to use this topology as it has many different advantages. It is very simple to add different devices, if the company expands in the future. It happens from time to time, that there is a cable failure- by using star topology, one failure cable does not bring down the entire network, but only pc/device that using this cable. Star topology, has a lot of support in nowadays, as it is the most common topology. It can be easily upgraded to faster speeds, which is very important, when...

...VoIP as a New Trend Student Name University Name Professor Name 06/20/2010 There is a new trend that has taken the networking technology to the next level. It all started in the 90’s looking for a less expensive way to make phone calls across the world. Both residential and commercial customers have been looking for a cheaper way to make local and international calls. This new revolution is called Voice over Internet Protocol (VoIP). If I had to put this in plain terms, this technology allows voice traffic to be transmitted over the Internet. VoIP is a new application of Internet Protocols (IP) that enables the conversion of voice communications into data packets and then these packets are transmitted via an IP network such as the Internet. “VoIP services convert your voice into a digital signal that travels over the Internet”. (fcc.gov) Similar to using your analog phone system and going through a Public Switched Telephone Network (PSTN), now you will be using a digital phone and going through the Internet. All you need to get the ball rolling and to be part of this new trend is a decent Internet connection at home and you could say goodbye to that plain old analog telephone line forever. Most cable companies are offering service bundles that include cable television, Internet access and telephone services. These companies are transitioning from the telephone analog system to the VoIP systems. A lot of costumers are switching over to VoIP for the simple reason of saving...

...running head: WIRELESS TECHNOLOGY Wireless technology Justin Armstrong Dr. Biswajit Panja CIS 505 March 4, 2012 Objectives 1. Compare the pros and cons of 3GL and 4GL technology to determine the best uses of 3GL and 4GL technology in today’s applications. 2. Describe how an enterprise would use 3G, 4G, WAN, and WIMAX to improve business. Explain why they would use one (1) solution over the remaining three (3). 3. Analyze the changes in 4GL technology since the printing of the textbook in 2009 and identify those of importance for a user of 4GL technology. 4. Take a position on the following statement, “Wireless application protocol is a necessity for wireless communication organizations and their users.” Then, explain your position with supporting evidence. Compare the pros and cons of 3GL and 4GL technology to determine the best uses of 3GL and 4GL technology in today’s applications. So what are the benefits or otherwise of using a 3GL over a 4GL and vice versa. For me it certainly depends on all the usual factors that drive any technology decision. Cost of product, support, flexibility, the human factor, tool lifecycle, vendor direction and target platforms being a few that come to mind instantaneously. (Dare, 2008) The pros of 3GL * 3GL’s are quicker to react to emerging markets and development trends: Generally the suppliers of these 3GL tools are inventing the future. They don’t often agree with each other but they certainly have the...

...newer and more improved algorithm. When WPAv2 was finally released, many devices began to be created to be compatible with the AES algorithm WPAv2 uses. There still have not been any major hacks or attacks on a WPAv2-AES network that would cause the Wi-Fi alliance look into using another algorithm a replacement. WPAv1 is too easy to hack so it is not recommended and WPAv1 is now susceptible to multiple types of attacks. There are several different ways you can help to protect yourself and your information. Verify your spam in your e-mail to make sure a file accidentally was not forwarded to spam. There are also others to improve your security.
