Write a Linux bash shell script that should take an IP address as an argument from the command line and ping to that address. The script should output the result of the ping as either reachable or unreachable depending on the result of the ping. Two example outputs of the script may look like as below. Take the screen shot of the script itself and the outputs of the running script for 8.8.8.8 and 23.23.23.21 to submit.

————1——

$ ./yourname_script.sh 8.8.8.8

The IP address 8.8.8.8 is reachable

—————2————-

$ ./yourname_script.sh 23.23.23.21

The IP address 23.23.23.21 is not reachable

There are many things in this example that let you know this is not a real opportunity for employment, but more likely an opportunity for someone to gain access to your computer and your company’s private information. However, real-world attempts are not always this obvious and can take many forms. Social engineering, phishing, malware, spoofing, hacking, and card skimming are all risks to our personal and business information.

In your discussion post, consider the scenario presented here, or a real-world example of phishing, as you respond to the following:

• Describe indicators you can use to identify a phishing email.
• Explain the importance of employee knowledge concerning phishing attempts.
• Provide several recommendations for information security practices that could be implemented to limit the risks and impact of phishing emails.

When responding to your peers, provide an additional suggestion for an information security practice they did not identify, and explain how your suggested practice would deter or reduce the impact of phishing within the company.

To complete this assignment, review the Discussion Rubric.

Check the slides “OS Security II,” pg. 4-8. You are to implement a Dictionary Attack with and without Password Salt program in either C/C++ or Python.

If you are not familiar with measuring execution time in C++, see the following website:

https://www.geeksforgeeks.org/measure-execution-time-function-cpp/

If you are not familiar with measuring execution time in Python, see the following website:

https://stackoverflow.com/questions/1557571/how-do-i-get-time-of-a-python-programs-execution

See the following steps.

1. Accept a user password of length N as keyboard input to your program. You can determine your own length N.

2. Compute the hash of the password from step 1.

Your hash function H() is simply the checksum. (See Assignment 2)

3. Now you become an attacker and try to find the password of length N.

Try every combination of length N password and for each combination, compute the hash and compare to the hash of the password from step 2.

Measure execution time.

4. Now let’s reinforce our password using the password salt. Accept an arbitrary non-negative integer number as keyboard input to your program.

5. Compute the hash of the concatenated password salt and password from step 4 and step 1. To compute the password salt portion of the checksum, you can treat the entire password salt as EITHER a single integer OR multiple one-byte integers.

6. Now you become an attacker and try to find the concatenated password salt and password.

Try every combination of an arbitrary non-negative integer number and length N password and for each combination, compute the hash and compare to the hash from step 5.

Measure execution time.

NOTE: your program should have separate functions for the checksum and the two dictionary attacks with and without the password salt by the attacker.

Many business environments have both visible and invisible physical security controls. You see them at the post office, at the corner store, and in certain areas of your own computing environment. They are so pervasive that some people choose where they live based on their presence, as in gated access communities or secure apartment complexes. Alison is a security analyst for a major technology corporation that specializes in data management. This company includes an in house security staff (guards, administrators, and so on) that is capable of handling physical security breaches. Brad experienced an intrusion—into his personal vehicle in the company parking lot. He asks Alison whether she observed or recorded anyone breaking into and entering his vehicle, but this is a personal item and not a company possession, and she has no control or regulation over damage to employee assets. This is understandably unnerving for Brad, but he understands that she’s protecting the business and not his belongings.

When or where would you think it would be necessary to implement security measures for both?

Part 1 Your finished flowchart should get an air temperature from the user for each of five days. It should then display

• the average temperature for the five days,
• the highest of the five,
• and the lowest of the five.

To complete, you will need to do the following:

·         Initialize the variable in main that needs to be initialized (you don’t need to initialize the variable that will hold the user’s input). In getHigh, initialize the two variables that need to be initialized.

•  Add a call to the subchart getHighest Test your flowchart and make sure it works.
•  Create a subchart called getLowest, put in the proper steps and call it from main.
• Create a subchart called getTotal, put in the proper steps and call it from main.
• Create a subchart called getAverage and call it from main.
• Create a subchart called displayOutput where you display the required output in a user friendly way.

Directions

The manager at James Otis Tax Associates has asked you to submit a report describing the technology hardware and software needed to build a computer network for the new office. The manager has asked you to describe the computer system for each new employee, including an explanation of the purpose for each selected technology component, and to identify specific software programs that the employees would need. He has also asked you to describe the security measures needed to support the systems. In your explanation, include how your knowledge of human-computer interaction (HCI) impacted your choices for each component.

The manager has provided the following employee descriptions:

• Certified Public Accountant (CPA): The CPA is a senior position at a tax preparation company. The CPA will be not only handling sensitive customer data from personal tax returns but also preparing tax returns for corporate clients. The CPA is also responsible for the personal tax returns filled out by the tax and data-entry specialist employees.
• Tax Specialist: The tax specialist has the dual role of entering data and verifying that tax returns are correct. This position involves customer interaction in gathering data for minimizing taxes owed or maximizing tax refunds.
• Data-Entry Specialist: This position requires data entry for personal tax returns for customers who walk in the door. Although the data-entry specialist works with sensitive customer data, they do not have access to the tax returns once the returns are submitted to the tax specialist for review.

For each employee, you must:

• Describe all hardware components, including peripherals, needed to create the systems
• Identify specific software programs (more than one) that would be beneficial to each identified employee. Programs could include:
  • Operating systems
  • Applications such as:
    • Office automation products
    • Security products
• Describe security measures needed to support this system. Security measures could focus on:
  • Access
  • Administration and user passwords
  • Firewalls

Along with each description, explain the purpose of each technology component in each system. In your explanation, include how your knowledge of human-computer interaction (HCI) impacted your choices for components.

Finally, choose a network topology that could be used to connect all of the new employees identified by the manager. Create a Visio diagram to identify the networking equipment needed to enable the workflow between the employees.
