Go through the steps with me to show me how to use the DiskPart tool.

Design a program in Python programming language which has the following points.   Take input from user a file name with location which is present in client system. Copy the file to the server system with same format. The file can be at any format ( .txt, .jpg, .mp3 etc ). The file received status should be printed on server and sent to client. Use socket programming to perform the task. Paste the code and output snapshot.   Server Output: Waiting…   Client Output: Enter file name and location to send : d:\r.jpg Sending….   Server Output: Waiting… Receiving…   Client Output: Enter file name and location to send : d:\r.jpg Sending…. File Sent to Server.   Server Output: Waiting… Receiving… File Received from Client.

Java program with a simple encryption. Read from a file specified by the user and encrypt the content of the file using a simple shifting technique. Also, ask the user to input the shift size. Output the encrypted message to another file whose filename is also provided by the user. Example Output: Shift size: 1Message read from the file: HelloEncrypted message: Ifmmp Note: Provide a screenshot of the output with the same result with the example

You’ve created a PPT file contains a lot of pictures and two videos, the file size was X MB. You have to decrease the size of the file without deleting the objects Inserted on it. Suggest a solution .

In the class, we saw how we could hide a text file into a picture without changing its appearance. How this is possible?

Simple Encryption. Write a java program that reads from a file specified by the user and encrypt the content of the file using a simple shifting technique. Also, ask the user to input the shift size. Output the encrypted message to another file whose filename is also provided by the user. For example, Shift size: 1 Message read from the file: Hello Encrypted message: Ifmmp

A small insurance company has an online application system that allows its customers to interactwith the business (e.g., log claims). Backups of the customers’ details are done on a spreadsheetdocument stored on Google drive. However, anyone who has access to the Google drive link ofthe file can view and modify all the customer details. On the backup, the system administratordoes not have visibility of the modifications made on the file.  By analysing the scenario above, use the security design principles to criticise theoperations of the small insurance company and propose any two simple controlsthat could influence a good security program.

Answer the given question with a proper explanation and step-by-step solution.   Hello, I am trying to make a program that prints the contents of a file but whenever I try to run it, it just prints a bunch of question marks infinitely and this only happens when I run it on a UTM virtual machine(Linux terminal). It works fine when I run it on my Mac terminal so I am not sure if it has to do with the virtual machine or my program. Please help!! Image 1: cat.c Image 2: input.txt Image 3: output/results

Create a program (in Java or Python) to encrypt and decrypt messages using the Shift Cipher. Your program should behave as following: Ask the user if they want to encrypt or decrypt a message or quit the program. Ask the user for the key Ask the user for the message Print out the encrypted or decrypted message. Go back to step 1.

Find out if FFFF:0000 is a warm or cold booting and write the code of FFFF:0000

Experimenting with AES-”S symmetric key cipher. Note: You may use any programming language that provided libraries for AES. Descrion: This assignment consists of two parts:PART 1: write a program that uses AES-12/1 to decrypt a message. The program should be named "decrypt", and should deal with three files that contain the encrypted text as a stream of bytes, the 128-bit key for decryption stored as a stream of bytes, and file outcome of the decryption, respectively. o To test this program, here's an example of an encrypted message a. its 128-bit secret key PART 2: you will try to use "brute force" to decrypt an encrypted message, where you only have Sirrst 96-bits of the 12S-bit secret key (last 9 bytes of the secret key are he program should be called "findk", and should deal with two files that contain the encrypted text as a stream of bytes and the first 96-bits of the key, respetively. The program should decryptedn standard the the missing h6177 of the key in hexadecimal,…

To the command interpreter, most of the commands that a user types are executed by finding a program on the disk with that name and running it. A few commands are not mapped to programs on the disk Where do they reside?

Computer Science in linux An important concept in computer security is the principle of least privilege. Each user must be able to access only the information and resources that are necessary for legitimate purposes and activities. With the “principle of least privilege” in mind, how would you configure your Unix/Linux system to designate a small set of users as printer admins? For example, users steve and bob will need to perform printer administration tasks. This includes running the lpadmin, cupsaccept, cupsreject, cupsenable, cupsdisable, cancel and lprm commands as root. How will you configure the system to allow these printer admins to do their jobs without having any other kind of root user access? Provide the relevant config file entries. (Absolute pathnames required for commands)

Modify the scripts of Projects 1 and 2 to encrypt and decrypt entire files of text. An example of the program interface is shown below: Enter the input file name: encrypted.txt Enter the output file name: a Enter the distance value: 3

Implement a simplified version of the UNIX program "cp", which copies one file to another by changing the file permission (specified by the program). Use Low-level File Access functions such as create, open, read, write, close, etc.) toimplement this command

Write a shell file “hello.sh” that outputs “hello world” and the date. Then generate an executable file andrun it.Step1: build your script file (you need to write down all the processes to build a script file)Step 2: make your script file executable.Step 3: run your script file

Instead of using “>” to send nmap's output to a text file, and then using cat to print it into    | grep … | mail …, what single piped commands could have done it all at once without going out to a text file first?

For the following Computer Science question: Does the following Set-UID program have a race condition vulnerability? Explain your reasoning. if(!access("/etc/passwd", W_OK)) {     /* the real user has the write permission*/     f = open("/tmp/X", O_WRITE);     write_to_file(f); } else {     /* the real user does not have the write permission */     fprintf(stderr, "Permission denied\n"); }

Imagine that a file block is located at disk block 581132. What does this information tell you?
