Modify an existing Java Web application that violates several Payment Card Industry guidelines and recommendations. Your task is to locate the issues, identify what is wrong and then fix the code. You will discuss each issue in terms of why the issue may cause a security vulnerability, and how you specifically fixed the issue. The current code, uses Java JSP and Servlets to allow a user to login to their account and view credit card data stored in the database. The functionality is relatively simple but several PCI compliance rules have been violated that will prevent the application from being approved by a PCI software auditor. You should first load up the application, populate the database and make sure the application is working in your environment as expected. The application uses the Java Derby relational database. The script used to populate the application is attached as well as the Java web project itself. You should be able to open the existing project using NetBeans. However; you may need to load the Derby drivers to the libraries for the project. Once you have the database loaded, you can try the application. (This assumes you have properly installed the Java EE when you installed NetBeans). Email:john.doe@test.edu Password: mypassword Review the code and perform analysis as needed. You should experiment with  application as well as reviewing the code to identify possible areas of security concerns. You don’t have to be an expert in JSP/Servlets, html or css to be able to find some of the issues that you have read about in the PCI documentation. However; it is recommended you experiment with the code so you have a baseline familiarity with the model and know how the JSP and servlets communicate with each other. Focus on the PCI compliance issues found in sections 6 through 9 (see attached jpg file) as you look for issues. There are multiple issues and you should work to fix and document as many as possible.Submission: Provide all of your modified Java code, your modified database script and a word document describing how you addressed each issue. You should clearly describe the code and what PCI compliance issue were violated and how you fixed it. You should provide screen captures as needed to support your findings and improvements.

Please submit a zip file. The zipped file should contain three separate ipython notebook files ’1-generator.ipynb’, ’2-HOF.ipynb’, and ’3- generator-HOF.ipynb’ for the first, second and third problems respectively.Python’s Generators and Streaming.Compute the median age of the Citibike’s subscribed customers. You are required to read data line by line and are not allowed to store the entire data set in memory. Indeed, you should not have any containers (e.g. list, dictionary, DataFrame, etc.) with more than 100 elements in memory. You should use yield when you want to iterate over a sequence, but don’t want to store the entire sequence in memory as shown in the Codes/Lab3.What to submit:Turn in an ipython notebook with the plot of the histogram of customers age and print out a single number showing the median age of the subscribed customers.Python’s Higher Order Functions: This is how you can read the file and transform it to a list of lists. import pandas as pd df = pd.read_csv("citibike.csv") rows = df.values.tolist() (a) Determine the number trips that gender 1 made, and that gender 2 made. We can do this by just counting the number of occurrences of ”1” and ”2” in the gender column (2pt): <Read file> <YOUR HOF EXPRESSION> # After this, you should get something like # (37805, 7848) (b) Count the number of trips per birth year using higher order functions (2pt): <Read file> <YOUR HOF EXPRESSION> # After this, you should get something like # {"1900.0": 22, "1901.0": 1, "1910.0": 2, "1922.0": 4, ... "1995.0": 256, "1996.0": 124, "1997.0": 94, "1998.0": 59, "1999.0": 17} What to submit:Turn in an ipython notebook print out the results for problems (a) and (b)3. Extract the first ride of the day from a Citibike data stream. The first ride of the day is interpreted as the ride with the earliest starting time of a day. For the sample data, which is a week worth of citibike records, your program should only generate 7 items (one for each day).Streaming Computation: you are asked to complete the task using steaming computation methods. You can only iterate the data set once using yield as shown in Codes/Lab3. You can store a container (e.g. list, dictionary, DataFrame,etc.) with maximum 7 elements in memory. The data set has been sorted by the starting time.What to submit:Turn in an ipython notebook print out the birth years of the first riders each day for problem.

DescriptionThis assignment is an opportunity for you to practice using virtual functions. You are to implement 7 simple classes with 0 or 1 member variable:Animal (Grandparent)Mammal (Parent)Human (Grandkid)Cat (Grandkid)Bird (Parent)Owl (Grandkid)Duck (Grandkid)In your main.cpp, you will have the following code:#include <iostream>#include "animal.h"using namespace std;int main() { Cat cat; Human human("English"); Animal *animals[4]; animals[0] = new Duck; animals[1] = new Owl; animals[2] = &cat; animals[3] = &human; for (int i=0; i < 4; i++) { animals[i]->make_sound(); } delete animals[0]; delete animals[1]; return 0;}Expected Output I quackI hootI meowI speak EnglishGivenYou are given the following file:lab15_0_animal_kingdom_main.cppWhat to SubmitSubmit two files for this lab:animal.hanimal.cppTipsFor some of your classes, you will have a string member variable "sounds_made" to hold either "quack", "hoot", "meow", or "speak"For the Human class, you will have a string member variable "language" which can hold the mother tongue language the human speaks.Not all classes will need to implement make_sound() function.Watch Video Lecture 15-4 for virtual function discussion.RequirementsWrite as few lines of code possible, make use of the power of inheritance.Clear and concise comments and programming style.
