Lab 03 Specifications

please give the solution for this attached document.

thank you.

Lab 03 Specifications Last update ­ 2016­05­28, 18:11Z Due : Specified on the Blackboard assignment page. Late submissions will automatically be marked as late and NOT GRADED . Please make sure you submit your assignment far in advance of the stated deadline, so that you avoid losing credit due to bad networks, etc. It is recommended that you start early and if you have questions, ask them in the course Blackboard Discussion forum. If you wait until the last minute to ask questions, it’s very likely that nobody will answer you in time. It is also recommended that you turn in something, even if it’s not complete. Even if you weren’t able to complete the assignment, taking the time to explain what you tried and what problems you faced will likely prevent you from getting a zero. Grading : Grading is somewhat subjective in this assignment, on a scale of 0 to 10, roughly equivalent to a standard grading scale where 10 would be an A+ (Excellent), 9 would be a B+/A­ (Good), 8 would be a C+/B­ (Fair), etc. In this particular assignment, if you do all that is asked of you, you should receive a 10. If you neglect, or poorly explain 2 or more minor items, you should receive a 9, and so on. The primary purpose of this third Lab Assignment is to give you hands­on experience in issues related to password security, which serves as the primary basis for access control to computing systems. In this assignment you will use a popular password cracking software system, John the Ripper ( JtR , or simply, john ). This system is used by many administrators to audit their own systems. Needless to say, it is highly unethical to use this for the purpose of hacking into a system without permission of the system owners. You will run john with a provided password file, and then you will experiment by generating some of your own passwords and allowing john to try to crack them. Then, you will explore some online password cracking environments and password generators. The steps, outlined below, are to ● Either use the same VM you used in Lab Assignment #01, or import a new one ● In the VM ○ Run john on a password file prepared to you ○ Create your own passwords with openssl , some easy, some hard, put them in a password file, and try to have john crack them. ● In a web browser ○ Go to hash generator pages and create your own passwords, some easy, some hard ○ Go to password cracking site that uses a “rainbow table” and try these passwords

In the description of this lab, I have annotated areas where I expect something from you by highlighting requirements in Red Bold . To complete this assignment, you will (this is repeated at the bottom of the assignment) ● provide thorough explanations in areas that I request ● provide images of the scenarios that I request If you run into problems that you cannot resolve, you should first utilize the Blackboard Discussion forum for this class and seek help. If you are still unable to resolve the problem, you should provide a very clear explanation of what you have tried, and what has gone wrong . Please note that in the following instructions, I am refraining from telling you exactly how to perform each step. I am simply telling you what you need to do and, where I think it might be necessary, providing you with some additional guidance. In some cases, you will have to read documentation and figure some things out for yourself. I am also very aware that many of you are not familiar with Linux. I am trying to keep this simple enough that it won’t be too hard for you, but at the same time I think it’s good for me to force you to figure out a few things on your own. Downloading the Virtual Machine You may use the same VM that you used in Lab Assignment #02. If you do, it has the advantage that the terminal prompt is already set up with your name in it. If you choose to download a new one (it’s exactly the same as the one you’ve downloaded before), refer to the Quick Notes on Installation of VirtualBox, and Import/Usage of the Virtual Machine document from Lab Assignment #02 to import it and to set up the terminal command line prompt so that it has your name in it. Using john John the Ripper is available both in a free and a commercial form ­­ http://www.openwall.com/john/ ­ but I have already installed it for you in the VM. Documentation (not the best in the world) is available at http://www.openwall.com/john/doc/ . Note that within the document there are links to OPTIONS and EXAMPLES. Once you boot the virtual computer, open up a terminal or two, and cd to the JtR directory, where you will do all your work.
