Expert Solution & Answer
Chapter 10, Problem 2TF
Explanation of Solution
Output file:
- A file where the data are written is called as “output file”. The output file is created on the disk and allows the program to write a data to it.
- The “output file” must be accessed using the file name and must be closed after the usage of the file.
- If the file is not closed properly it can cause a loss of data. Because, the data that is written to a file is stores in a buffer first.
- After closing a file, the buffer saves the contents into the disk.
Write mode:
The ‘w’ mode is used to open an output file with writing option. If the specified file not exists in the disk then create a new file with corresponding file name.
Purpose of ‘w’ mode when the file already exists:
If the disk has the specified file, then the file contents will be erased and the new contents have to be written into the file...

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:

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.
