Journal Article: Moral philosophy

Your submission must include the following information in the following format: 

DEFINITION: a brief definition of the key term followed by the APA reference for the term; this does not count in the word requirement. 

SUMMARY: Summarize the article in your own words- this should be in the 150-word range. Be sure to note the article’s author, note their credentials and why we should put any weight behind his/her opinions, research or findings regarding the key term. 

DISCUSSION: Using 300-words, write a brief discussion, in your own words of how the article relates to the selected chapter Key Term. A discussion is not rehashing what was already stated in the article, but the opportunity for you to add value by sharing your experiences, thoughts and opinions. This is the most important part of the assignment. 

REFERENCES: All references must be listed at the bottom of the submission–in APA format. Be sure to use the headers in your submission to ensure that all aspects of the assignment are completed as required. Any form of plagiarism, including cutting and pasting, will result in zero points for the entire assignment.

Suppose a text file contains ASCII characters ‘0’ and ‘1’ representing bits in human readable form. For example, test.txt may contain 111111110000000 which means its size is 16 bytes. A simple method for compressing the file by a factor of 8 is to represent a block of 8 ‘0’ or ‘1’ ASCII characters as a single byte. Thus test.txt which is 16 bytes long can be compressed into a file that is 2 bytes long where the first byte contains all 1’s and the second byte all 0’s. The resultant compressed file is a binary file since the first byte is not an ASCII character.

Code an app, bitpacker, that reads from stdin the input filename which follows the same specification as Problem 3. However, instead of using getchar(), use the library function fgets() whose the second argument allows specifying how many bytes, at most, should be read which helps prevent array overrun. Process the data in the input file 8 characters at a time by reading them into a 1-D array, char rawdat[8]. Compact the eight ‘0’ and ‘1’ characters in rawdat[] into a single byte using the bit processing techniques discussed in class. Write the resultant byte into an output file with suffix “.P”. For the above example, test.txt.P. We will allow the size of the input file not to be a multiple of 8. Since we are compacting 8 ASCII characters ‘0’ and ‘1’ into a single byte, we will use padding to handle files whose size is not a multiple of 8. For example, if text file test1.dat contains characters 1111111100000000111 (file size is 19 bytes), we will pad the last three characters 111 with 00000 so that the byte containing bit values 11100000 is written to test1.dat.P. To note that we padded the original data with five 0 bit values, we will change the suffix of the output file to test1.dat.P5. For test.txt where no padding was needed, the output filename will be test.txt.P0. Thus the last character of the filename specifies how much padding (0-7) was added.

Code bitpacker as a single main() function.  Test and verify that it works correctly.

1. What did you learn?
2. Did you learn anything that surprised you such as “I didn’t know I could use this technique to try to hide data?!”
3. Please list at least four different ways that an bad actor may try to obfuscate their tracks.
4. Once you have identified four different ways that a bad actor may try to evade scrutiny, please identify how you might be able to uncover those techniques.

In this lab we will look at data which is unencrypted and data that is encrypted. We will use a tool called GNS3 to simulate two routers that are connected via a point-to-point link. We will run data through this link while looking at the packets going through it. The tool we will use to view the data is Wireshark which is probably the most important tool we as network engineers have in our toolbelt. Let’s answer the following questions as we go through the lab.

Ÿ 1. What is the cleartext data that is being sent in the ping between the two PCs? _____________________

Ÿ 2. What is the protocol used for the ping utility? ____________________

Ÿ 3. How many ping messages do you see? _____________________ Why? ________________________________________________________________________

Ÿ 4. Is this data encrypted or unencrypted? _____________________________

Ÿ 5. Now let’s make a change in the router. What types of messages do you see now? Does it look the same as the messages we saw before we made the change to the router? ________________________

Ÿ 6. What protocol do you see now? ____________________

Ÿ 7. Are you still able to see the source and destination MAC address? __________What layer is this you are looking at the MAC address in? _____________

Ÿ 8. Are you still able to see the source and destination IP address? __________What layer is this you are looking at the IP address in? _____________ 

Ÿ 9. Can you see the cleartext data you saw before? ____________________________

Ÿ 10. Explain the ESP protocol. Does what we see in Wireshark make sense? Write a paragraph answering these two questions.

By various theorem’s of prime numbers.  Write a 1 to 2 page paper on the similarities and differences of Fermat’s Theorem to Euler’s Theorem.Need 500 words in the paper.
