You have assumed the role of managing the technology infrastructure at a zoo. You will develop a working program either an authentication system for the zoo designed to follow the specifications outlined in the overview. You will also provide detailed documentation describing your development process. Select from one of the following options as the basis of your program.
Authentication System (JAVA)
For security-minded professionals, it is important that only the appropriate people gain access to data in a computer system. This is called authentication. Once users gain entry, it is also important that they only see data related to their role in a computer system. This is called authorization. For the zoo, you will develop an authentication system that manages both authentication and authorization. You have been given a credentials file that contains credential information for authorized users. You have also been given three files, one for each role: zookeeper, veterinarian, and admin. Each role file describes the data the particular role should be authorized to access. Create an authentication system that does all of the following:
- Asks the user for a username
- Asks the user for a password
- Converts the password using a message digest five (MD5) hash
o It is not required that you write the MD5 from scratch. Use the code attached to this document and follow the comments in it to perform this operation.
-Checks the credentials against the valid credentials provided in the credentials file
o Use the hashed passwords in the second column; the third column contains the actual passwords for testing and the fourth row contains the role of each user.
- Limits failed attempts to three before notifying the user and exiting the program
- Gives authenticated users access to the correct role file after successful authentication
o The system information stored in the role file should be displayed. For example, if a zookeeper's credentials is successfully authenticated, then the contents from the zookeeper file will be displayed. If an admin's credentials is successfully authenticated, then the contents from the admin file will be displayed.
- Allows a user to log out
- Stays on the credential screen until either a successful attempt has been made, three unsuccessful attempts have been made, or a user chooses to exit
On a separate word document provide the Pseudocode with corresponding commentary. The pseudocode should demonstrate your breakdown of the program from the problem statement into programming terms. Explain whether the pseudocode differs from the submitted program and document any differences and the reason for changes.
