Requirements:

APA Format

The writing assignment requires a minimum of two written pages to evaluate the history.  You must use a minimum of three scholarly articles to complete the assignment.  

 Briefly respond to all the following questions. Make sure to explain and backup your responses with facts and examples. This assignment should be in APA format and have to include at least two references. Assignment must be at least 600 words. Include a coversheet with a title, your name, class ID and date at minimum. 

1. When should the architect begin the analysis?
2. What are the activities the architect must execute?
3. What is the set of knowledge domains applied to the analysis?
4. What are the tips and tricks that make security architecture risk assessment easier?

· Create the physical data model for the logical data model that you submitted in IP3. This should include all of the data definition language SQL.
 

Your submission should include all DDL needed to:
 

Create the tables
Create the primary keys
Create the foreign keys
Add DML statements to:
Add data of 1 customer who buys from the company
Provide the DML to add 1 employee who interacts with customers
Give DML to change data of the employee, giving the commission a 25% increase
Give DML to delete the customer and employee data
Write 3 SELECT statements:
To select the customer details
To select the employees details
To show which employee services which customer
 

Submit your Word document and make sure that it contains the following:
 

Screenshot of the ERD, logical data model from previous assignments.
The DDL to create the tables, including the table definition and the primary and foreign key definitions.
SQL to add data to the tables
Add data of 1 customer who buys from the company
Provide the DML to add 1 employee who interacts with customers
Give DML to change data of the employee, giving the commission a 25% increase
Give DML to delete the customer and employee data
Write 3 SELECT statements:
To select the customer details
To select the employees details
To show which employee services which customer

Identify a personal project of your choosing. This could be a family vacation, plans to clean or organize a part of your living space, etc. 

Provide a brief summary of your project that includes the scope of the project and at least three goals or objectives of the project.    

Windows stores passwords using the NT LAN Manager (NTLM) hash.  This hash is created by hashing the plain text password with the MD4 algorithm.  There is no salt used.  The lack of salt enables the use of a rainbow table to lookup passwords from their hash.   For this assignment you will create a rainbow table for a set of passwords. 

More about NTLM: http://techgenix.com/how-cracked-windows-password-part1/

For this assignment you will create a Rainbow table for NTLM passwords.   Use the following list of steps as a guide.

1. Use the sys library to read a command line argument that is the name of a password dictionary file.
   For your submission used the password dictionary file found at this link: http://www.openwall.com/passwords/wordlists/password-2011.lst (Links to an external site.)
2. Open the password dictionary. 
3. Loop through the contents of the password dictionary one password at a time.
   • Strip any leading and trailing whitespace characters.
   • encode the word as ‘utf_16_le’ (https://docs.python.org/3/library/stdtypes.html#str.encode (Links to an external site.))
   • Use the Python library hashlib to hash the password with the md4 algorithm.
     • import hashlib
     • hashlib.new() to select an algorithm
     • use update() to create the hash
     • use hexdigest() to refer to the hash
   • Store the password in a Python dictionary with the hash as the key. (https://docs.python.org/3/tutorial/datastructures.html#dictionaries (Links to an external site.))
4. Sort the list of keys from your dictionary
5. Use a for loop to print all keys and passwords. Print on hash and password pair per line. Structure each line as follows to allow a password to be looked up easily from it’s hash:
   [hash]:[password]
6. Store the output of your program as rainbow_table.txt. 
   *** Run your program as ‘python3 rainbowtable.py dictionary.txt > rainbow_table.txt’
7. Name your script rainbowtable.py

Business Case: Local airport

The parameters.

15,000 passengers a day

530 flights daily  

350 fulltime employees

There are three databases in the Airport’s data center.

1-Passenger database to record and authenticate each passenger in the airport

2-Employee database to record and authenticate each employee in the airport

3-Flight database to record each flight in the airport

Every day the following processes must be done:

Process 1:  For each passenger: a Boarding Pass will be calculated, prepared, and stored. The final version of the boarding pass will be printed on the printers at the airport

Process 2: For each aircraft; Flight logs along with the passenger checklist will be prepared and stored.

Process 3: One-week old Passenger and Flight data will be stored in long-term storage (archive)

Question 1 Identify cyber assets based on the NIST definition in the given Local airport business case. List the cyber assets.

Question 2 What are the steps that you would follow to fulfill the requirement of the NIST Risk Management Framework for the Airport? Write each step

Question 3 Do your search and find common cybersecurity threats in aviation.  And prepare your Risk Assessment Report (RAR) Based on the following threat sources

• Adversarial
• Structural
• Environmental

Question 4 List the Risk Treatment Alternatives you would consider for each cybersecurity threat for the Airport.

WORST EXPERIENCE EVER

 You are a new employee of DigiFirm Investigation Company. As part of your company orientation, you are being exposed to each area of the computer forensics investigations firm.DigiFirm is preparing to set up a new on-site forensics laboratory facility. Kim Blake, the laboratory manager, has asked you to select three examples of software or a state-of-the-art piece of equipment that could be acquired and used in your organization’s new lab. Your supervisor mentioned to Kim that you could use some indoctrination to the DigiFirm technical capabilities, and what better way than to have you jump right in and help the company plan the new lab. You will help make some important decisions regarding investment in equipment and/or software. For this assignment:

1. Research forensic lab tools and equipment.
2. Choose three examples of software and one state-of-the-art piece of equipment that would benefit the lab.
3. Write a proposal that covers:
   1. Your choices include costs.
   2. The reasons for choosing them.
   3. The benefits and limitations (if any) of each choice.

This paper should be written in Microsoft Word (or compatible), Font: Arial, 12-point, double-spaced, Citation Style: your choice, and a length of 3-4 pages. 

Do a bit of research on-line. Find a criminal case that involved Digital Forensics. 

Using WORD, write an ORIGINAL brief document of 300 words or more describing the case and the how digital forensics were used  in the investigation.
