Please respond to the following:

• A web service is a software component that resides on a web server. Give at least two examples of when to use a web service. Explain why you think using a web service is required in those situations.
• Flesh out your thoughts and interact with your classmates. Post your initial response by Wednesday each week and then return on a couple of other days to see what’s going on with the discussions. 

Estimation of time required for brute-force search attack on the password-based encryption

(To use the attached program, do not use your own program,please)

This assignment asks you to estimate the time required for successful brute-force search attack on password-based encryption using JCA in Java. It assumes that you have done Lab 1, Lab2, Lab3 (see attachment).

Make a list of passwords, mentioned in item 3 of Section 1.2 of Lab 1 instructions (page 2)

For password-based DES encryption implementation in JCA (Lab 2 and Lab 3) fix some salt and iteration count and record an average time required for encryption/decryption (done in Lab 3);

For each of the passwords above estimate the time required for successful brute-force search attack, assuming that an attacker knows:

• the predefined plaintext;

• the ciphertext produced;

• the salt;

• the iteration count;

• but no password.

Investigate how the time required for the attack depends on the iteration count;

Consider a variant of the attack, in which an attacker knows everything as above, except the iteration count, and estimate the time required to recover the passwords;

Compare your estimated time with the estimated time returned for the same passwords by online services (Lab 1, page 2) and propose plausible explanation of any observed differences.

Write a report on the above, providing an evidence for your arguments (e.g. snippets of code used to estimate time required for one encryption).

i have attatched the powerpoint aswell. 

Discuss the importance of Disaster recovery and how a business can benefit from having a plan. .

It must be at least 450 words and have references.

No plagiarism and no grammar mistakes and need APA format.

properly site the references.

Select from the following list four (4) topics and discuss. Use only 70-words max per topic to discuss and present your answer. The discussion questions this week are from Chapter 9  (Jamsa, 2013).

Chapter 9 topics:

• List the security advantages of cloud-based solutions.
• List the security disadvantages of cloud-based solutions.
• Define and discuss the data wiping process.
• Discuss how a cloud-based solution provider may reduce the risk of a DDoS attack.
• Define and discuss hyperjacking attacks.
• Define and discuss guest-hopping attacks.

NOTE: You are required to use at least two-peer reviewed sources (besides your textbook) to answer the above questions.   

Questions:

1.       Why does evidence-based medical practice need IT support?

2.       Should only randomized clinical trial results be used to make treatment decisions? Why?

3.       List at least 3 reasons clinical practice guidelines are not used consistently in the US.

I expect 3 pages of fact-based material to answer these questions.

Paper should be APA formatted with citation.

• Briefly respond to all the following questions. Make sure to explain and backup your responses with facts and examples. This assignment should be in APA format and have to include at least two references.
  • When should the architect begin the analysis?
  • What are the activities the architect must execute?
  • What is the set of knowledge domains applied to the analysis?
  • What are the tips and tricks that make security architecture risk assessment easier

Week 5 Written Assignment

Each assignment will be an essay written in APA format (see below). Each essay should be no less than 1500 words on the topic (s) noted below.
