Evolution of Technology

Question 1

Discuss “The Changing Nature of Cybercrime” presented in Chapter One in Computer Network Security and Cyber Ethics (4th ed.) by examining the following question:

How has the evolution of technology impacted the complexity, severity, and frequency of cybercrimes over the same periods of time examined in Figure 1.1?

Support your statements with logic and argument. Your initial post must be supported by at least two credible, academic or professional sources. Post your initial response early and check back often to continue the discussion. Be sure to respond to your peers’ posts as well.

Question 2

Write python programs to solve the following two problems. Make sure you comment your program appropriately.

• (lab11.py) Keep asking the user for a number and depending on whether the number is even or odd, print out an appropriate message to the user until the user types “q”. Hint: how does an even / odd number react differently when divided by 2.
• (lab12.py) The goal of this exercise is to write a cyclic cipher to encrypt messages. This type of cipher was used by Julius Caesar to communicate with his generals. It is very simple to generate but it can be easily broken and does not provide the security one would hope for.

The key idea behind the Caesar cipher is to replace each letter by a letter some fixed number of positions down the alphabet. For example, if we want to create a cipher shifting by 3, you will get the following mapping:

Plain: ABCDEFGHIJKLMNOPQRSTUVWXYZ Cipher: DEFGHIJKLMNOPQRSTUVWXYZABC

The program prompts the user to enter plain text and the shift value and then it prints out the cipher text.
