Write a paper with min Of 4 pages APA format with summary, 7 references.

Lists five tools that can be used by security administrators, network administrators, and attackers alike. 

Search the Web for three to five other tools that fit this description. 

Using a Web browser and the names of the tools you found, find a site that claims to be dedicated to supporting hackers. 

Do you find any references to other hacker tools? 

If you do, create a list of the tools along with a short description of what the tools do and how the tools work.

Python programming

  1. This homework tests your knowledge of File Handling and use of Lists data type.
  2. Adhere to the naming conventions discussed in class for variable names, program name and function names
  3. Use meaningful names for variables, functions etc
  4. If there are two words in the variable use first word lowercase and first letter of second word upper case i.e., firstName or underscore between 2 words i.e first_name
  5. Include appropriate comments in the code
  6. Output should be displayed similar to as mentioned against each problem
  7. Indent the lines of code appropriately

1. Write and read file

a ) write_num.py (30 points)

Create a num_list file to write a range of numbers from 1 through 101.

Hints:

   Define main ():

   Open a file named as num_list in write mode.

   Use for loop to write a range of numbers from 1 through 101 into the file.

   Close file

b)read_num.py (40 points)

Use num_list file which got created in number 1.a. Write a program that will prompt the user to enter the name of the file (i.e. num_list.text), and display the first 10 lines of the file’s content. Use try/except construct to capture any file opening related errors such as invalid file name etc.

Hints:

                   Define main ():

                   Declare variables: line and counter, and initialize them

                   Prompt for file name: use input function

                   Open the file in read mode.

                   Read the lines in the file with readline function: ‘inline.readline()’ and initialize counter to 1

                   Use a while loop to read and display the first 10 lines

                                   Use rstrip method to remove n characters at the end of the line

                                   Print the line

                                   Update the counter when the line is read

                    Close file

Expected output:

Enter the name of the file: filename.txt

2. numanalysis.py (30 points)

Write a program that asks user to enter a series of 10 numbers. The program should store the numbers in a list then display the following data.

1. The list contents

2. The lowest number in the list

3.  The highest number in the list

4. The total of the number in the list

5. The average of the number in the list

Hints:

Define main ():

                       Declare variables and initialize them

                       Create an empty list 

                       Use the for loop with the range function to loop through 10 numbers. 

                       Prompt the User to enter the numbers from 1- 10. 

                           Ex: Enter number 1 of 10: 

                        Use append function to populate the  list

                        Use min, max, sum, functions to find the low , high and total number of the list.

                              Ex:  low = min(number_list)

                         Print the list contents

                        Print Low, high , total and average numbers of the list.

Expected output :

List: [#, #, #, #, #, #, #, #, #, #]

Low: #.##
High: #.##
Total: #.##
Average: #.##

6 pages(not including cover and reference page) APA formatu 

Find a peer-reviewed scholarly journal article discussing implementing information technology globally. Complete a review of the article by writing a 2-3 page overview of the article. This will be a detailed summary of the journal article, including concepts discussed and findings. Additionally, find one other source (it does not have to be a peer-reviewed journal article) that substantiates the findings in the article you are reviewing.
You should use Google Scholar to find these types of articles.
Once you find the article, you will read it and write a review of it.  This is considered a research article review.
Your paper should meet these requirements: 

  • Be approximately four to six pages in length, not including the required cover page and reference page.
  • Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
  • Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. 
  • Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.
