Program Plan Intro
Unified Modeling Language (UML)
Unified Modeling Language (UML) is a modeling language in software engineering, which is used to visualize the design of the proposing system.
- In software development life cycle, it comes under the “documenting the program” phase.
- UML is used to document the developing system; this documentation helps the end user to understand the whole project.
- It visualizes all the components used in the developed object-oriented software; it shows all the elements and its relation.
Class diagram:
Class diagram is a static model which represents the system’s static structure and its relationship using attributes, relationships, objects, and operations.
- The relationship between the classes in the class diagram is called association.
- It is represented by drawing a line called association path between classes and placing the labels in between the association path.
- The instance of one class can be associated with more than one instance of another class and it is referred as multiplicity.
Steps to create class diagram:
- Identify objects
- Identify the attributes and behaviors
- Draw association between the classes.
Representing the class diagram:
- Every class in the class diagram is represented using a rectangle.
- The rectangle is divided into three parts,
- The first part contains the name of the class
- The middle part contains the attributes and derived attributes
- The last part contains the methods.
| Class name |
|
-Attribute name |
| +Operation name() |
Explanation of Solution
Attributes:
- Initially, identify the reasonable attributes for “CreditCard” class.
- The “CreditCard” contains the card number, card name, expiry date for card, and so on.
- So, let us take the followings are the attributes for “CreditCard” class.
- “cardNo”
- “name”
- “cardExpiryDate”
Expert Solution
Explanation of Solution
Behaviors:
- Initially, identify the reasonable behaviors for “CreditCard” class.
- The “CreditCard” contains the “getCredit”, “getPurchase” and so on.
- So, let us take the followings are the behaviors for “CreditCard” class.
- “getCredit()”
- “getPurchase()”
Expert Solution
Explanation of Solution
The UML class diagram for credit card is shown below:
The “CreditCard” class is shown in the following class diagram:
Explanation:
In the above diagram,
- The class name is “CreditCard”.
- The “cardNo”, “name”, and “cardExpiryDate” are attributes of “CreditCard” class.
- The “getCredit()” and “getPurchase()” are methods or operation name of “CreditCard” class.
- “getCredit()” method is used to gets the credit card amount from bank.
- “getPurchase()” is used to purchase the products by using the credit card.
Examples of objects of this “CreditCard”class:
First object:
The first object is “customer1” for this “CreditCard” class is shown below:
Explanation:
In the above diagram,
- The “customer1” object for “CreditCard” class.
- Assign the “cardNo” as “123456”, “name” as “XXXX” and “cardExpiryDate” as “03/02/2001” are the attributes of the “CreditCard” class.
Second object:
The second object is “customer2” for this “CreditCard” class is shown below:
Explanation:
In the above diagram,
- The “customer2” object for “CreditCard” class.
- Assign the “cardNo” as “234578”, “name” as “YYYY” and “cardExpiryDate” as “12/11/2022” are the attributes of the “CreditCard” class.
Third object:
The third object is “customer3” for this “CreditCard” class is shown below:
Explanation:
In the above diagram,
- The “customer3” object for “CreditCard” class.
- Assign the “cardNo” as “341579”, “name” as “ZZZZ” and “cardExpiryDate” as “01/02/2010” are the attributes of the “CreditCard” class.

Objective: The objective of this assignment is to gain practice with pen testing a live web
application running on a remote server. The live web application is a known vulnerable web
application called DVWA (Damn Vulnerable Web Application) with security settings set to low.
The web app is running on an AWS EC2 (Elastic Compute Cloud) instance running Ubuntu 22.
Note: The point of this assignment is to step it up a notch, we learnt about different web
application vulnerabilities and applied that knowledge, now we are going to pen test and
enumerable the vulnerabilities of a web app + the underlying infrastructure it is running on.
Before you begin please find out what your IP address is and place it in this sheet so that I can
track who is doing what: IP Addresses.docx .

The host computers use private IP address space: 192.168.2/24. Each host is trying to establish 2 TCP connections to a remote webserver through the NAT router. The IP address of the webserver is: 130.12.11.9. Now do the following: 1 a. Assign IP addresses to the interfaces of the hosts and the router. For the router, assign arbitrary addresses. List these addresses. b. Now create a NAT translation table as taught in the class for all TCP connections. Assign arbitrary port numbers as required.arrow_forward

Create a flow table for s2 that implement these forwarding behaviors. Your table should have 2 columns one for match and the other for actions, as taught in the class.arrow_forwardBased on the last digit of your Kean ID: Create an LC-3 program that compares 3 personally assigned to you numbers stored in memory and finds the maximum of them.
