Question
Chapter 14, Problem 14.2E
Program Plan Intro
Ability of system:
The number of cyber-attacks and even the complexity of the attacks have been increasing gradually. It is very important to increase the ability of the system so as to protect the system from cyber-crime. In order to protect the system against cyber-attack, redundancy and diversity play very important role.

John's query willreturn the same results all three times it is executed as they are run in the same session.
John's queries run at10:16 and10:20 produce the same result, which is different from the one at 10:14
John's query run at 10:16 waits until 10:18 to produce results, waiting for the commit to happen.

Word FrequencyWrite a program that reads the contents of a text file. The program should create a dictio-nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word “the” appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and its frequency.arrow_forward3.) File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. For example: codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would be assigned the number 9, the letter B would be assigned the symbol @, and so forth. The program should open a specified text file, read its contents, then use the dictionary to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file. Write a second program that opens an encrypted file and displays its decrypted contents on the screen.arrow_forward
- Returns an US standard formatted phone number, in the format of (xxx) xxx-xxxx the AreaCode, Prefix and number being each part in order. Testing Hint: We be exact on the format of the number when testing this method. Make sure you think about how to convert 33 to 033 or numbers like that when setting your string format.

Here are some notes to help you work the problem: • strcpy(char *dst, char *src) copies the string at address src (including the terminating '\0' character) to address dst. It does not check the size of the destination buffer. You will need to know the hex values of the following characters:arrow_forwardA ROP (Return-Oriented Programming) attack can be used to execute arbitrary instructions by chaining together small pieces of code called "gadgets." Your goal is to create a stack layout for a ROP attack that calls a function located at '0x4018bd3'. Below is the assembly code for the function 'getbuf', which allocates 8 bytes of stack space for a 'char' array. This array is then passed to the 'gets' function. Additionally, you are provided with five useful gadgets and their addresses. Use these gadgets to construct the stack layout.
