Important Dates: 

Handed out: 12-Oct-2020

Deadline: 3-Nov-2020 at 16:59 GMT 

Please ensure that you submit your work on time.

• This coursework counts as 10% of your final mark. 
• Please read guidelines on plagiarism in the study guide and course documentation. 
• This coursework requires knowledge about XML Schema, XSLT, JSON and Document Parsing. 
• Learning outcome:

 ◦ Use data-interchange formats (XML and JSON) and techniques appropriately to create documents and handle data. 

 Data Description

           Consider an XML document (WebAppInterface.xml): 

<?xml version="1.0" encoding="UTF-8"?> <interface id="RESTController">  <package>uk.ac.le.cs.wt</package> <extends> <from>Remote</from> </extends> <import>java.rmi.Remote</import> <import>java.rmi.RemoteException</import> <import>java.net.*</import> <abstract_method name="authenticateUser"> <access_level>public</access_level> <arguments> <parameter type="String">user</parameter> <parameter type="String">password</parameter> </arguments> <throws> <exception>RemoteException</exception> <exception>SecurityException</exception> </throws> <return>boolean</return> </abstract_method> <abstract_method name="activateUser"> <access_level>public</access_level> <arguments> <parameter type="URL">link</parameter> </arguments> <return>void</return> </abstract_method> </interface>

This XML document describes a Java interface below:

package uk.ac.le.cs.wt; import java.rmi.Remote; import java.rmi.RemoteException; import java.net.*; interface RESTController extends Remote{ public boolean authenticateUser (String user, String password) throws RemoteException, SecurityException; public void activateUser(URL link); }

Tasks:

Task 1: [40 Marks]

Write an XML Schema (WebAppInterface.xsd) that allows validation of the provided XML document. Note that the schema must be consistent with these rules in Java: 

• An interface may extend one or many interfaces. 

• There can be only one package statement 

• There can be zero to many import statements 

• An interface can have zero to many abstract methods 

• A method only allows one value to be returned (or void) 

• A method can only have zero or one visibility modifier * 

• A method can accept zero to many arguments

 • Exception(s) may be thrown from a method 

* If a method has no visibility modifier then it is accessible only within its own package (default visibility); assuming all methods are non-static. (Hint: Related lab exercise – Week 1)

(Hint: Related lab exercise – Week 1)

Task 2: [30 Marks] 

Write an XSLT stylesheet (WebAppInterface.xslt) that takes the provided XML document as input and generates an HTML document as follows: 

RESTControler

Operation	Argument(s)	Return
authenticateUser	User:String,password:string	Boolean
ActivateUser	Link: URL	Void

Note: You may show the result in a different page layout or colour scheme. The page must display the controller id, return type and the parameter list of each method. (Hint: Related lab exercise – Week 2/3)

{  "abstract_method": [  {  "name": "authenticateUser",  "access_level": "public",  "arguments": [  {  "type": "String",  "variable": "user"  },  {  "type": "String",  "variable": "password"  }  ],  "throws": [  "RemoteException",  "SecurityException"  ],  "return": "boolean"  },  {  "name": "activateUser",  "access_level": "public",  "arguments": {  "parameter": {  "type": "URL",  "variable": "link"  }  },  "return": "void"  }  ] }

Note: A Java template (WebAppInterfaceParser.java, and you will need xercesImpl.jar and xmlapis.jar which are provided on Blackboard) is provided for Task 3. However, you are allowed to use any programming languages or parsers for this task as you wish. If so, please include a text file README.txt explaining how to run your code. 

Note that this JSON output was deliberately formatted in this way to prevent people from using offthe-shelf XMLtoJSON function provided by certain APIs. If there is only one parameter in the method then it should be structured as an object (e.g. parameter: {}) while if there are multiple parameters, you should print it as an JSON array using [].

(Note: You are free to use any parsers, but the implementation of the parsing technique must be your work. The program must generate the JSON output specified above (e.g. must not contain “package”, “import”), which means you are not allowed not use any off-the-shelf XML-to-JSON libraries for the conversion e.g. toJSONObject)

Submission 

• Zip all files in a single zip file for submission. 

o WebAppInterface.xsd 

o WebAppInterface.xslt 

o WebAppInterfaceParser.java (or in your language of choice) 

• The archive should be named CO3102_CW1_email_id.zip or CO7102_CW1_email_id.zip (e.g. CO3102_CW1_yh37.zip). 

Your submission should also include a completed coursework plagiarism coversheet (print and signed PDF or image). You need to submit the zip file via Blackboard and you are allowed to resubmit as many times as you like before the deadline. Marks for any coursework which does not have the accompanying cover sheet will be withheld till you provide one.  

Marking Scheme

Note: In addition to the sample XML provided in Table 1, additional XML documents will be included in the test suite.

 Part 1: XML Schema validity checking will be automated. In total, a test suite consisting of 12 XML documents will be used for the assessment. The marks will be distributed according to test results. 

Part 2: XSLT will be compiled and applied to 7 test cases (XML documents) for the assessment. All HTML pages will be checked by TA(s) manually. The marks will be distributed according to test results. 

Part 3: In total, 7 test cases (XML documents) will be used the assessment. Any JSON generated by your XML Parser will be checked by an JSON validator. The marks will be distributed according to test results. 

Anonymous marking 

We operate an anonymous marking scheme. All submitted files will be renamed using anonymous fingerprinting generated by SHA256.

Case Study Analysis Guidelines and Rubric

  

IT 380 Module Three Case Study Analysis Guidelines and Rubric

Overview: This case study analysis will help you analyze a cybersecurity scenario and identify which principles were violated. Each skill in this paper is an essential part of the final project and accompanying milestones in this course.

Prompt: Use the articles from the Module Three required resources to analyze the cyber security occurrence, determine which principles were violated, and recommend appropriate policies to prevent recurrence.

Scenario: In February 2015, as many as 80 million customers of the nation’s second‐largest health insurance company, Anthem Inc., had their account information stolen. This compromise affected customers in at least 14 different states where Anthem provided services.

The hackers gained access to Anthem’s computer system and got information including names, birthdays, medical IDs, Social Security numbers, street addresses, email addresses, and employment information including income data. Both current and former customers were exposed during this breach.

So, while this was an attack against a medical provider and it resulted in a massive data breach, regulatory requirements were not sufficient to help prevent this breach. Because no actual medical information appears to have been stolen, the breach would not come under Health Insurance Portability and Accountability Act (HIPAA) rules, which govern the confidentiality and security of medical information.

Based on the Test Out sections from this module and the additional module resources you have reviewed, your paper should address the following critical elements:

 Identification of cyber security principles that were violated and rationale of cause

 Analysis of cryptography that would have helped prevent this breach

 Recommendation of additional policies that would have been useful to mitigate the breach or even prevent the breach

Rubric

Guidelines for Submission: Your paper should be submitted as a 2‐ to 3‐page (in addition to the cover and reference pages) Microsoft Word document with double spacing, 12‐point Times New Roman font, and one‐inch margins. All sources must be cited in APA format.

Assessment Task

The assessment task is to rework a report on a computer network design, implementation and testing.

Please see enclosed details

Networking Report – please read very carefully

 

         

XYZ are a company in the South of England. They have an office in Southampton with staff in three departments, Sales, Marketing and Admin. A new network is proposed. Each department will have its own router. The router in the Admin department will have a connection to an Internet Service Provider router to provide Internet connectivity for all departments. The business network must use an interior gateway routing protocol.

 

 

The tasks are as follows:

1)           Design an IPv4 and IPv6 addressing scheme for the network (including the interfaces on the ISP routers connected to the company office).

Use 192.168.0.0/24 network address subnetted into three networks for Sales, Marketing and Admin each with 62 possible usable addresses.

Use 198.51.100.0/30 as the network address for the ISP

Use the following IPv6 network addresses do not subnet them.

2001:db8:cafe:1::/64

2001:db8:cafe:2::/64

2001:db8:cafe:3::/64

  Design, implement and test a network with routers and switches and essential additional services including DHCP, DNS and a webserver to provide network services and business network applications.

2)           Run tests to demonstrate that you have formulated a correct solution to the problem and full network connectivity is possible using ipv4 and ipv6.

3)           Recommend and demonstrate configuration of device security policies  for routers and switches on the network.

Write up your work in the form of a report that discusses and analyses the design of the network and the addressing scheme. Also discuss and analyse the configuration and commands that you used to configure the addresses, routing protocols and authentication. Discuss and analyse the results of the tests that you made on the network.  Formulate conclusions and recommendations from your work and the results. The report should address all points raised in the marking scheme below.
