Describe how hacker might go about cracking message

1) Suppose that Eve runs a key server. Alice downloads a key from the key server which Eve claims is Bob’s public key. Bob downloads a key from the key server which Eve claims is Alice’s public key.

a. Given that Alice and Bob both assume that they have the correct public keys for the other party, and assuming that Eve can intercept any messages passed between Alice and Bob, is there any way that Eve can read the encrypted communications between the two parties? If so, how could she do it, and would Bob or Alice know that Eve was reading their messages?

b. What steps could Alice take to ensure that the public key which Eve claims belongs to Bob is actually correct?

Part 2: Essay Question. Maximum length: three (3) pages (double spaced). Use APA format for in-line citations and references.

Compare and contrast symmetric and asymmetric encryption algorithms. Your response should include a brief overview of the cryptographic basis for each type of algorithm, and a comparison of their relative strengths and vulnerabilities. Describe how a hacker might go about cracking a message encrypted with each type of algorithm. Suggest a specific application for each type of algorithm where the advantages clearly outweigh the disadvantages.

Discussion

“Stego and ADS” Please respond to the following:

o Briefly compare and contrast steganography, cryptography, and digital watermarking. Determine two strengths and weaknesses of each based on their similarities and differences. Explain whether or not you perceive these data-protection forms as mutually exclusive.

Identify the responsibilities of a project manager

Identify the responsibilities of a project manager

Your task is to write a 4,000 word essay on the following topic. An appropriate essay structure must be used.

Background:

The Sydney Opera house is an architectural marvel of the modern world. However from a project management perspective many people see it as a failure.

The project was unique and developmental. Many new technologies were employed and there were many innovations and changes to the scope throughout the project. Many people support the concept that the project was never finished.

In 1967 the cost was estimated at A$6million and by the time it was “completed” in 1973 more than A$100million had been spent on the project (more than 16 times the original budget).

What went wrong?

Much has been written about the lack of communications, the project scope creep, the lack of ability to understand complex technology and the political interference in the project. Most documentation comments about the complex array of committees who tried to control the project and the difficulty the architect faced in dealing with these committees. It was impossible for project managers to manage when their work was governed by committees who could not agree.

There was no process where the decisions reached by committees could be brought to a forum where a project management decision could be made.

The Assignment Task:

Your essay is “Buildinga New Sydney Opera House” from a project management perspective. ?It is not a description of what took place but a discussion essay that may be informed by some of the history of the project.

Issues you should address are:

? How to establish an organization with the capability to undertake the task?

? What special project management skills do you envisage will be required?

? How will the project management team for developmental project handle new ideas and innovative technological developments that may indicate scope, resource and budget “creep”?

? What communications plan will best suit a project of this nature?

? Make a list of all potential stakeholders and attach this as an appendix to your essay

? How would you go about building relationships with groups such as the committees mentioned above?

Rationale

This assessment task covers first six topics and has been designed to ensure that you are engaging with the subject content on a regular basis. More specifically it seeks to assess your ability to:

? Identify the responsibilities of a Project manager when participating in a real world project;

? Define the role of management in projects, particularly from the view point of the practitioner as a member of the project team;

? Apply project management skills, methods, techniques and tools to a real world problem typical of a project manager;

? Explain areas of knowledge relevant to project management; and

? Discuss the many problems facing the project manager and to note the “best practices” being utilized in order to produce effective, efficient and quality projects on time and within budget.

Develop a security plan for a threat detection system

Develop a security plan for a threat detection system

Your task is to develop a Security Plan for a threat detection system employing relevant technologies. The Plan could be divided into the following sections:

Mobile technologies and commerce

Task A :

Question: For this assignment, you need to plan, research, and, use your initiative to express the knowledge you learnt in this subject as well as your own independent thinking and reasoning.

Possible topics

Your attention in this paper can be focused on any of the following topics covered in our text:

· Information Management / IT Architecture.

· Database, Data, Warehouse, and Data Mining.

· Networks, Collaboration, and Sustainability.

· CyberSecurity, Compliance, and Business Continuity.

· E-Business & E-Commerce Models and Strategies.

· Mobile Technologies and Commerce.

· Social Media.

· Enterprise Systems and Applications.

· Performance Management Using Data Visualization, Mashups, and Mobile Intelligence.

Approach

Choose a topic which you are interested in and/or which is related to your work. You should do this as early as possible. Once you have chosen a topic, read our text carefully followed by detailed research. Once this is done, you should set up a structure/a series of subtopics and decide what to write under each section (subtopic).

Here is a suggested structure (you don’t have to follow it, but your own structure must be logical):

Abstract: a condensed summary. If someone reads your abstract only, he/she should understand your main points. You may want to write this section last;

Index terms: list the key words used in your paper;

Introduction: introduce the topic you are going to write about. This section must be related to the topics you learnt during the Session. However, you should branch out by carrying out your own research to enhance this section;

Subtopics and supporting argument: write a series of body paragraphs with sub-points;

Conclusion: Many students get confused between the conclusion and the abstract. In the conclusion, you can reflect on how your topic relates to larger issues; evaluate the concepts you have presented; issue a call for action on the part of your audience; ask questions generated by your findings; make predictions, recommend a solution or give a personal statement about the topic.

With your structure in order, you have a skeleton for your paper: you can now begin by writing out your analyses of the passages you have chosen. As you write and revise, you may have the need to add to your analyses or to re-order your chosen arguments. Using a structure as the skeleton for a paper in this way can carry you more than halfway to a completed draft.

Types of papers

Academic papers can be broadly categorized into 2 types:

1. Argumentative Papers;

2. Analytical Papers.
