Implement function get_contact(contacts, name) that returns a string. The contacts and the name parameter are both type string. This function checks for the name string in the contacts string and returns that person’s contact information. If the person is not found, the function returns, “name not in contact”. Assume input is always valid. Assume the same name is not repeated in contacts.

[You may use split(), range(), len() ONLY and no other built-in function or method]

Examples:

              contacts = “Frank 703-222-2222 Sue 703-111-1111 Jane 703-333-3333”

              name = “Sue”

              print(get_contact(contacts, name))

              returns:

              703-111-1111

              name = “Sam”

print(get_contact(contacts, name))

              returns:

              name not in contact

A common argument from contrarians of the human impact on global warming about the increase in CO2 levels of the atmosphere is that the increase in carbon dioxide by humans is only a small percentage of the total sources of emitted CO2. In other words, the argument is that humans cannot be the cause of the increase in warming of the climate since the added emissions is a small percentage of what is added to the atmosphere from natural forces like volcanoes. In your response, address the following: What are the natural carbon sources and sinks? How does the emission of carbon by humans affect this balance? Why is this argument short-sighted of the feedback mechanisms built into our ecosystem? How would you explain to this contrarian that his argument is missing a larger picture?

Write a program that performs the following two tasks:

1. Reads an arithmetic expression in an infix form, stores it in a queue (infix queue) and converts it to a postfix form (saved in a postfix queue).
2. Evaluates the postfix expression.

Use the algorithms described in class/ lecture notes. Use linked lists to implement the Queue and Stack ADTs. Using Java built-in classes will result in 0 points. You must use your own Stack and Queue classes (my code is a good starting point). Submit the code + example runs to validate your code. Submit UML chart to show the program design.

TO ANSWERER: Please give a clear, complete, and detailed program in Java. Thank you!

1. Write a brief description of a vulnerability found in the scan, including the operating system on which it was found, its risk factor, and its CVSS scores.
2. Are the results of default scans different than the credentialed scan?
3. Why might that be?
4. What types of vulnerabilities might an attacker without any credentials be able to identify and exploit?
5. This was a simple three computer LAN. How much more complicated would this process be for 100 computers? What about an enterprise with 10,000 computers on their LAN/WAN?
6. Consider a cloud-hosted Infrastructure as a Service (IaaS) environment with many new, internet-accessible systems regularly being built and brought online. What advantages or challenges might there be with regard to vulnerability management in the cloud?

No Hand drawings, please.

Consider the following scenario and then answer the corresponding questions.

ABC Travel and Tourism specializes in providing tourist packages to customers across the globe and the company has decided to develop an in-house software system that will help customers search for travel destinations based on popularity, budget, visa restrictions, government policies and attractive climatic conditions. Customers will also be able to book their air tickets, hotel and transportation (rental car, public transportation, cab services) through this system. Prior to the booking, the system will allow users to check for their visa eligibility to travel to destinations outside of their country of citizenship. Users will also be able to review and rate destinations or hotels using the system. The company also offers pre-set packages and if a customer decides to go with a specific package, they will be asked to provide the dates for their travel. The system will find an airline reservation, hotel/ transportation choices and create an itinerary for the customer. Customers will not be allowed to customize the pre-set packages.

Once the booking is done, the system should send a notification to the users on the purchase confirmation within 2 hours. Cancellations will incur a 25% penalty, if users are “Gold” members. In all other cases, the reservations will be non-refundable. Customers can pay using their credit cards or Paypal.

Upon your review complete the following:

1. Identify ALL MAJOR the tables relevant this case, the primary key, foreign keys, attributes and data types. For each table, list the fields, description, datatype and description about that field as suggested in the format below. (30 pts). (Hint: Refer to your class diagram).

2. Apply 1^st, 2^nd and 3^rd normalization rules for your tables. Explain how each table satisfies these normalization rules. (Hint: You may end up creating intersection tables as needed, in addition to the tables identified for question #1). (20 points)

(Please see normalization examples from the lecture notes and show the normalization process for the tables as applicable)

3. Draw an ER diagram for this case including the tables, relationships, cardinality and all the fields. (10 points)

FRAUDD EXAMINATION

Case 4

Stephanie Adkins is an accountant who is trained in forensic accounting. She is an experienced fraud investigator. She was recently hired by Lake Side Hotels, a closely-held corporation, to investigate a company manager who is suspected of taking kickbacks from vendors.

Stephanie gave Lake Side her standard engagement letter stating that the scope of the engagement would be limited to investigating only one suspect. It did not guarantee findings or results.

According to the provisions of Stephanie’s engagement, she was to communicate directly with Bernie James, the company’s controller, and Amanda Peterson, the outside attorney.

At the first meeting of this team, Bernie indicated that Lake Side had received four separate anonymous tips about possible kickbacks. All the tips indicated that Laurie Miller, an evening manager, was taking kickbacks from food vendors. One tip named a particular vendor, the Mid States Beef Source, a company that supplies meat to the hotel’s restaurants.

Stephanie asked if Bernie had any documentation that supports Laurie Miller’s possible involvement in kickbacks. Bernie had no documentation but hoped Stephanie could help them substantiate the information from the anonymous tips. He was concerned that kickbacks would hurt the hotel financially.

Amanda, the outside attorney, said that she had already talked to several hotel employees and was convinced that Laurie was guilty.

Kickback schemes can be difficult to uncover, so Stephanie wanted to proceed cautiously.

Bernie wanted to confront Laurie immediately. He was convinced she would confess if he told her that he had evidence against her.

Stephanie asked what evidence Bernie had. Bernie said, “Only the anonymous tips, but I know she will confess if we bluff.” It was against Stephanie’s professional principles to lie and she said so.

“Detectives do it all the time on cop shows,” Bernie said. Stephanie insisted she would need to run the investigation her way or she wouldn’t be able to undertake this engagement.

In relation to this scenario, write responses to the following:

What steps might Stephanie follow to proceed with her investigation?

What mistakes, if any, have already been made in the investigation?
