Explanation of Solution

Object Oriented Programming:

  • The real world entities are called as object like pen, pencil, chair etc. The object oriented programming is a paradigm or methodology to design a program using objects and classes.
  • The Object Oriented Programming main aim is to implement real world entities that is classes, inheritance, abstraction, polymorphism and object.

Three pillars of Objected Oriented Programming:

The object oriented programming language consists of three pillars. They are:

  • Encapsulation
  • Inheritance
  • Polymorphism

Encapsulation:

  • One of the fundamental concept of OOP is encapsulation. In Java, the encapsulation is a mechanism of wrapping the variables and code acting on the methods together as a one unit.
  • The variables of a class will be hidden from another classes and it can be accessed only though the methods of their present class.
  • It is also called as “data hiding”.

Inheritance:

The derived classes do not inherit the constructor functions of the base classes.

  • Inheritance is the concept of inheriting the members and properties of a base class from the derived 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 . Tasks: 1- Start by connecting to the target, I did not install a TLS certificate on purpose that is why you are going to connect via http and not via https: http://3.99.221.134/dvwa/login.php 2- Broken Authentication:…
