...update them; it’s difficult to come up with effective ones that we can still remember, so we procrastinate changing them for months, even years. We all know that this is bad practice, but the alternative along with the painful, irritating password creation and memorization process, is sometimes more than we can tolerate. Password is simpler and cheaper than others, more secure forms of authentication like special key cards, fingerprint ID machines, and retinal scanners. While passwords are becoming more and more vital component of system security, and with that they can be cracked or broken relatively easily. Password cracking is the process of figuring out or breaking passwords in order to gain unauthorized entrance to a system or accounts. The difference between cracking and hacking is that codes are cracked, machines are hacked. One simple way of cracking and in a variety of different ways; the most simple is the use of a word list or dictionary program to break the password by brute force. Another easy way for potential intruder to nab passwords is through social engineering: physically nabbing the password off a Post-it from under someone’s keyboard...

...Knuckle Cracking Have you ever had the urge to crack your knuckles? This “bad” habit has long been thought of as a contributor to joint trouble, particularly arthritis. Even though the mechanisms behind it aren't perfectly clear, research suggests habitual knuckle cracking is not a significant risk factor for arthritis, though it may have several other negative side effects (Kevin DeWeber, 2011). Though the exact mechanisms behind knuckle cracking are still debated, that popping sound is likely not from bone-on-bone contact. To keep them working smoothly, most joints are surrounded by a membrane filled with lubricating fluid and gases. When a joint is “cracked” an event called articular release occurs where the gases are thought to escape the membrane, causing the characteristic “pop!” sound associated with knuckle cracking (R., 1995). The same workings lie behind the “cracking” associated with fingers, wrists, ankles, and necks (R., 1995). Despite joint cracking being normal and fairly common throughout the body, knuckle cracking in particular has long been blamed as a contributor to painful arthritis. However research suggests habitual knuckle cracking isn't forceful enough to cause the wear and tear associated with arthritis (MARINA G. PROTAPAPAS, 2002) (Kevin DeWeber, 2011) (Jorge Castellanos). In fact, knuckle cracking might actually cause temporary relief in joint pain and reduce symptoms of arthritis, hence the popularity of such practices among chiropractors (Kevin...

...4. The implementation of networking technology has created more risk for businesses that useinformation technology because business networks are now connected to the internet andother networks external to the organization. This has made it easier for people to gainunauthorized access to the organizations networks. 5.Information extortion occurs when an attacker steals information from a computer system anddemands compensation for its return or for an agreement not to disclose it. For example, if a hacker gains unauthorized access to a celebrity’s computer and discovers embarrassing photosor videos of the star, he could then blackmail the star into giving him money in exchange forkeeping the photos quiet. This causes not only a monetary loss for the celebrity, but also a loss of privacy . 6. Employees constitute one of the greatest threats to information security because employeemistakes can lead to the revelation of classified data, entry of erroneous data, accidentaldeletion or modification of data, the storage of data in unprotected areas, or they could fail to follow procedures to protect data. 7. The first, most basic step is to set up the computer so that the screen and keyboard are not visible to persons passing by. If you have an LCD monitor, adjust the viewing angle to makew it as difficult as possible for anybody else to read your screen. Also, be aware of all people near the computer; frequently look and verify that no one is watching your screen or keyboard. If someone...

...Attack Methodology and Countermeasures Strayer University SEC420 Professor Gillen July 24, 2015 Attack Methodology and Countermeasures When most people hear the term “hacker” they think of an evil person committing crimes by hacking into their computers to steal, destroy and/or steal identities. This is so in some cases, but not all hackers are bad. Hackers are merely curious technically skilled individuals who gain unauthorized access to computers, networks of various companies, organizations and individuals. Good hackers are considered white hat hackers. They are the ones, who are hired to break into systems as a way of testing the vulnerabilities and security issues that may be present in the computer system. Consider this: company XYZ, a mid-sized corporation, is in the middle of satisfying their regulatory compliance needs. The manager of security at the company has been tasked by the CIO (Chief Information Officer) to report on the company’s current security posture. If the manager decided to outsource an ethical or white hat hacker in attempt to test their security measures. Over the course of this document various things the third party hacker would need from the company, things he or she would provide to the company and some predictions for the tests. In order to exploit the targeted systems the initial steps to gain as much information as possible about the targets. In this case, the manager is the contact in which questions may be posed.

...Evidence Collection Cases 1. In this case the first thing that first responders need to recognize is that the computer was on when the suspect was arrested and there may be evidence that they need to collect right away. If data of apparent evidentiary value is in plain view onscreen. The first responder should seek out personnel who have experience and training in capturing and preserving volatile data before proceeding. First responders should also be alert to the crime scene environment. They should look out for pieces of paper with handwritten notes, passwords, usernames, and software and hardware manuals. These forms of evidence also should be documented and preserved in compliance with departmental policies. In this case the computer should also be checked for DNA so investigators can match the suspects DNA to the arson crime scenes. Also TimeFrame Analysis can be used to link any files of interest to the timeframes of the investigation. All these things can help link the suspect to the crimes, and in doing so can help tell the insurance company whether the claims are valid. 2. Case 4-4 (bomb threat) A list of what items should be included in an initial response field kit to ensure preservation if digital evidence. The initial response field kit should be lightweight and easy to transport. With this kit, you can arrive at a scene, acquire the data you need, and return to the lab as quickly as possible. * Small computer toolkit * Large-capacity drive *...

...1.Explain the two different types of attacks that can be performed in Cain and Abel to crack user account passwords. Which do you think is the most effective and why? Dictionary attack is a technique of using a program that attempt to try a list of words on a program that protects the area you want to gain access to. For example, when attempting to password crack a Dictionary attack can scan a list of common single words such as “hacking”. However, more advance user often use other advance programs with the help of a dictionary to help mix in numbers or symbols in the word. Brute Force is commonly used on the last resort for cracking password, this attack is known as the least efficient attack. When dealing with short password, brute force...

...chapter 2 1. Why is information security a management problem? What can management do that Technology cannot? Management is an information problem due to the fact that policymaking and training of securing systems from users fall into the responsibility of their role. These responsibilities can include limiting access as well as disabling certain functions that are not related to the organizations’ function. Management can set policies that may arise due to improper uses or manipulations of systems and asses the threats that are unknown due to the introduction of new hardware and software. 2. Why is data the most important asset an organization possesses? What other assets in the organization require protection? The integrity of the data is most important because it relates to the overall company operations. Securing the data from people not authorized to see or change it ensures that the correct information about the company is being generated without interference or manipulations of data. Other important assets that requires protection are the computer terminals, networking infrastructure, which need to be protected from misuse from internal and external threats whether intentional or not. 3. Which management groups are responsible for implementing information security to protect the organization’s ability to function? The responsibility relies on several management groups such as CIO, who is responsible for the overall protection of system, but the CEO...

...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...

...Hacking Tools Paper A hacking tool is a program built for attackers to assist them in hacking. There are many different types of hacking tools. One of these hacking tools is called Nmap. Nmap is a security scanner that was originally designed by Gordon Lyon. It was built to find hosts and services on a network. Once it finds these hosts and services, it will then send packets to the target host and evaluate the responses. Nmap checks the network conditions during the packet run including latency fluctuations and congestion. It also figures out if a host is up or down and which ports are open or closed. Also, it can tell which operating system the target is using, the type of device and even the presence of a firewall. Another popular hacking tool is called Nessus. Nessus is a vulnerability scanning program. It is a free program designed to detect potential vulnerabilities on systems. It checks for vulnerabilities such as misconfiguration, allowing a hacker to control or access data remotely, default passwords, dictionary attacks, denial of service attacks, and also provides preparation for PCI DSS audits. The way in which Nessus works is it does a port scan first to figure out which ports are open, and then tries to exploit them. All of the tests are written in Nessus Attack Scripting Language. It then produces dozens of new plugins every week and is tested/scanned on a regular basis. John the Ripper is another hacking tool out there. This one is a password...

Recognize that information security must be made a top organizational priority. Sitting in the parking lot of a Minneapolis Marshalls, a hacker armed with a laptop and a telescope‐shaped antenna infiltrated the store’s network via an insecure Wi‐Fi base station. The attack launched what would become a billion‐dollar plus nightmare scenario for TJX, the parent of retail chains that include Marshalls, Home Goods, and T.J. Maxx. Over a period of several months, the hacker and his gang stole at least 45.7 million credit and debit card numbers, and pilfered driver’s license and other private information from an additional ...

...Valentine was able to use those tools to get Agatha out of the vault. The Adams family felt very relieved and very fortunate that Jimmy had these tools and was able to break into the vault and save Agatha. Although, his skills were always used for criminal activity, this time he was able to use his skill for good. Jimmy Valentine was dedicated to living a moral life because he helped Agatha from being trapped in the vault. Ralph D. Spencer risked his identity for the love of his life Annabel Adams niece, Agatha. When Valentine also known as the safecracker was trying to disguise himself as Ralph D. Spencer, a shoe salesman. He made the decision to risk his identity and use his safe cracking skills in order to save Agatha. When JImmy Valentine used his “old not right” safe cracking skills once again he used them for a good purpose this time. When JImmy was at the Elemore bank he risked his new way of living to help out the Adams family. “In a minute JImmy's pet drill was biting smoothly into a steel door.” Within a matter of 10 minutes JImmy had the Adams family all smiling with big smiles of relief that Agatha had been saved from being in the vault. They had no idea how they would save her because the door didn't have a key setup on it yet. As “Spencer” was in this crisis he responded by using his safecracking skills to save Agatha even though questions would arise as to how he knew how to get in the vault. While Jimmy quickly took out his suitcase with his tools in...

...Section I: Based on the information provided, we thought it would be best to first look at the provided software and instructions from the assignment. We decided to use the program that was given to us which was Rainbowcrack. The reason behind this being that none of us has had a large amount of experience cracking passwords and there seemed to be a lot of literature on how to use Rainbowcrack online. Dually, to be noted is that we were informed that salting was used on the passwords in order to make cracking them even more difficult. ----(Insert Addition or changes if necessary) Section II: The first thing we did was downloaded and extracted Rainbowcrack on to our respective machines. From there, after reading the documentation that was provided by rainbow crack (readme.txt), we learned that there wasn’t a set install that came provided, instead you click the specific .exe file to use that particular tool. After trial and error we decided that it would be easiest to use the rcrack_gui.exe in order to...

...Trade barriers and their effect on foreign direct investment in India and France. CERTIFICATION OF AUTHORSHIP: I certify that I am the author of this paper and that any assistance I received in its preparation is fully acknowledged and disclosed in the paper. I have also cited any sources from which I used data, ideas or words, either quoted directly or paraphrased. I also certify that this paper was prepared by me specifically for this course. While there are many differences in the political systems of India and France, there are also a number of interesting similarities. The French political system is special in two ways. Firstly, it is not a parliamentary system like the British one nor is it a separation of powers like in the USA, where the President must take account of congress. The French Fifth Republic is a semi-presidential system in which the president and prime minister are both active participants in the day-to-day administration of the state. When the president and prime minister come from opposing parties, the president is responsible for foreign policy and the prime minister is responsible for domestic policy. France is also different from most major democracies as it uses a two round single winner voting system, rather than the one round system, which is the system used in the United States and the United Kingdom. Like France, India also has both a prime minister and a president. India is a union of states. It is officially classified as a Sovereign...

...UNIVERSITE CATHOLIQUE DE LOUVAIN Louvain School of Management LLSMS 2062 European Business Report on Renault’s Strategy in India Professor: E. Cornuel Students: Barbier Théodora Cheffert Pauline Jadoul Thibault Kerstenne Nola Munster Diana Nguyen Kathy Academic year 2014 -2015 What other cars to introduce? Lower end of the market? Regarding the highly saturated lower end of the market, the launching of an ultra-cheap car does not seem to be the best strategy. Indeed, Suzuki and Hyundai are already major players on this segment. Moreover, Tata Motors, a well-established Indian manufacturer, announced the cheapest car in the world. Upper end of the market? Again, the competition is already struggling on this segment: GM, Toyota, Ford and Honda are already well represented on this market 1 . Although it is becoming more and more attractive due to the higher number of rich Indians, it seems dangerous to try this market regarding the strong competition. Our recommendation is therefore to invest in the middle end of the market. The reasons are growth opportunities and non-saturation of this segment. First, adapting the car to the local needs of the market is a priority, especially for India2, where mastering the local culture is a requirement. The features of the car would be the following: 1. The length of the vehicle should not exceed 4 meters due to tax measures (24%)2; 2. The style should be sportive, regarding the disastrous state of Indian roads and the trend...
