Malicious individuals have discovered several methods to attack and defeat cryptosystems. It’s important that understand the threats posed by cryptographic attacks to minimize the risks to your network systems. Identify one cryptographic attack and how you can protect against it. A substantive post will do at least TWO of the following: Ask an interesting, thoughtful question pertaining to the topic Answer a question (in detail) posted by another student or the instructor Provide extensive additional information on the topic Explain, define, or analyze the topic in detail Share an applicable personal experience Provide an outside scholarly source (please cite properly in APA 7)Make an argument concerning the topic. At least 1+ scholarly source should be used in the initial discussion thread. Use proper citations and references in your post.

The Physical Model was based on the idea that people did not really understand the work involved in the digital forensics world or how to treat it in court. With all the crime dramas on television, the average juror may now think that everything can be resolved in 60 minutes and is based on perfect DNA physical evidence and the digital “smoking gun” always found on the criminal’s computer.  How would you tailor your approach and reporting to address the fact that the jury may now think that without 100% conclusive evidence, the person should not be found guilty?  Please avoid discussions about the presumption of innocence or a position that circumstantial evidence is never sufficient to find someone guilty.  This discussion is for you to consider how you would convince someone that your circumstantial evidence is sufficient and how to counter the idea that perfect evidence is always available. Your word count should be between 250-500 words. Need this in APA formatting with title page and reference 

The purpose of project management and the SDLC is to increase successful software implementation. The article titled “IT Project Failure Rates (https://faethcoaching.com/it-project-failure-rates-facts-and-reasons/): Facts and Reasons” makes it clear that a lot of projects still fail.Identify an IT system development failure that occurred within the last two years. Do not repeat an example from earlier in the course or one that has been posted by another student.Analyze which project management concepts were not respected by the project managers and where in the SDLC these lapses occurred.Describe how you might have spoken up had you been on the steering committee.

A typical DMZ is a network virtualization schema when a particular network connects to at least two different networks with different security levels. What would be the Cloud-Based DMZ Architectures’  Challenges? Support your answer with Examples

Discussion: This week we focus on the movement of traditional IT staff.  To facilitate cultural assimilation, IT and non-IT must become more integrated.  What are some strategies to implement to allow this type of interaction to occur? Note: The first post should be made by Wednesday 11:59 p.m., EST. I am looking for active engagement in the discussion.  Please engage early and often. Your response should be 250-300 words.  Respond to two postings provided by your classmates.

 For this discussion board, you will need to research some best practices in allocating hardware to your virtual machines. In your initial post make sure to identify what your research showed as a best practice and if it is hypervisor-specific be sure to include the hypervisor.   Your initial post needs to be at least 250 words  For this lab you will research and compare the features of the various commercial Type 1 hypervisors available on the market.   You will choose at least 3 Type 1 hypervisors and look at the features, hardware requirements, and options and write up a comparison between them.  Ultimately after you have written up your comparison you need to make a recommendation as to which hypervisor you would use and explain why.  Write up your research including references and submit it for a grade

The above submission should be two -pages in length (one page for each question) and adhere to APA formatting standards. Use the APA template provided with this course.**Remember the page length does not include the APA cover page or any references**Both Homework 1 & 2 should be 2 different documents. 

 In this module, you learned that random numbers (or, at least, pseudorandom numbers) are essential in cryptography, but it is extremely difficult even for powerful hardware and software to generate them. Go online and conduct research on random number generators. What are the different uses of these tools besides cryptography? How do they work?
