Assignment OverviewUnit 4 – Individual Project

ASSIGNMENT DESCRIPTION

Deliverable Length: 2-3 additional pages of screenshots in design document and Java code project files zipped

OBJECTIVES

Part 1

Modify your Java application so that it is an easy-to-use GUI application where all of the interaction is performed on one screen. You will now take the individual components and translate them to a single interactive GUI interface using the following GUI components, container, the event listeners, and event subclasses to enhance your application as a more GUI-appropriate interface:

GUI components

Container

Event listeners

Event subclasses (at least 3–4 utilized)

ActionEvent

ItemEvent

FocusEvent

KeyEvent

MouseEvent

WindowEvent

ActionPerformed Method

Part 2

For this assignment, you are being asked to make sure you are exception handling by verifying that all of the customer-entered information is valid before the order is submitted to ensure order accuracy.

The customer information that the customer must now enter that should be validated includes the following:

Entered user name (must fill in a name)

Entered at least one sub to order

Selected all three attributes for sub (such as bread type, sub type, and sub size)

Entered delivery address that includes street, city, state, and zip code

Entered telephone number xxx-xxx-xxxx

In this assignment, you are adding in error handling to make sure the customer is filling in all of the required information.

To accomplish this task, you will be utilizing the following Java classes:

Methods in the character class and StringBuilder class to validate and manipulate characters in a string

Try… Catch for the exception handling of all input fields

Deliverable

The following are the Unit 4 Individual Project deliverables:

Update the title page for the Design Document with the project name (Unit 4 IP) and the date.

Add the following section header: Phase 4 Revised Application Screenshots.

Add screenshots of each distinct screen from your running application.

Name the document yourname_ITSD424_IP4.doc.

Submit the design document and the zipped Java project files for grading.

Please submit your assignment.

OBJECTIVES

Team Project Submission: Submit to the Unit 4 Group Project Area

This version of the Capstone project assignment is for grading this week. Submit the document containing completed Sections 1–4 from Units 1, 2, 3, and 4 to the Group submission area.

Continue using the template modified in Units 1, 2, and 3. Submit your Capstone project-related work to the Group submission area. Include the word “FINAL” in the document title. Your final version will then be available to share with your team. The instructor will grade the content and teamwork using this final version.

New Content for Week 4: System Development

Verbania has requested some functionality for its new social networking application. The following is a sample of the required functionality:

Account setup and log-in functionality

Creating a profile

Adding or removing friends

Posting to a discussion area

Complete the following steps:

Step 1: Work with the team’s Software Development Specialist to develop these functionalities. Develop use case diagrams, sequence diagrams, and class diagrams, as appropriate.

Step 2: The mobile application side of this solution will require secure and encrypted connections. Please work with your Security and Network Specialists to develop an appropriate solution for wireless communication in the mobile application. Include the optimum levels of encryption and network connectivity.

Step 3: As a final element, incorporate a Business Design Document (BDD) and a System Design Document (SDD) into the Capstone project paper. Include the team-suggested solutions for hardware or software, networking, security, as well as the integrated applications design (diagrams and database schema).

Your group must submit the following content:

The diagrams and explanations for the application design

The mobile application encryption and network connectivity

The BDD and SDD

Within the template, prepare 8–10 pages of content addressing the team’s System Development. Insert the content into the template document under Section 4.

The entire Group Project document must be submitted to the Unit 4 Group Project submission area for review and grading.

I’m working on a cyber security discussion question and need an explanation to help me study.

1. Many security applications exist for Linux in a wide variety of categories (anti-virus, firewall, intrusion detection, network monitoring, vulnerability scanning, etc.). Describe and discuss a couple of specific security applications for Linux.
2. Looking back on this course on Linux security, indicate one particular topic (or issue) that you are most interested in, and explain why.

How Good are you with  Cloud security solutions? in my case i would like to write about the below using IEEE Articles

* Access controls in cloud security solution

— Issues

— Solutions

* Data privacy in cloud security solution 

— Issues

— Solutions

Your initial posting is to be a detailed, well-organized response to the posed question.

Topic (((Cyber security Threat Environments and threat measures)))

For a quantitative study, your chosen research design must address reliability and validity issues. How will you insure the measures you are using are valid and reliable. What will you put in your research design to insure validity and reliability?

For a qualitative study, there are also issues your research design has to address, such as credibility, transferability, dependability, and confirmability. Address how these factors you would address in your qualitative study.
