Describe, in 350 words, an example of a very poorly implemented database that you’ve used or know that illustrates the potential for really messing things up. Explain an analysis of what might have caused the problems and potential solutions for them.

Submit a report that discusses the techniques used by malware developers to disguise their code and prevent it from being analyzed.  Give suggestions on how these techniques should be classified and ranked in the disaster recovery documentation.

 Discussion:
This week we discuss the overall process of developing new software.  Please also note the differences between software development and methods (200 to 300 words) references

Exercise

1. How is the IT function organized in your school or place of employment? Create an organization chart showing how the IT organization fits into your overall organization. Comment on how centralized or decentralized the IT function is.
2. Which software-development methodology would be best if an organization needed to develop a software tool for a small group of users in the marketing department? Why? Which implementation methodology should they use? Why?
3. Chapter 7 – Review the section on dealing with multiple locations and outsourcing.  Review figure 7.2 and note how virtual team communications further reiterates the importance of this model. 
4. Chapter 8 – Review the Siemens AG case study.  Note the importance of understanding the interrelationships amongst all the senior leaders at every location.  Pay special attention to Figure 8.1 and Figure 8.2. Note how the corporate CIO should engage with each of the regional leaders.  Why is this important?

Assignment 4: Truncatable Primes

Background

A left-truncatable prime number is one where the numbers resulting from removing the left-most digits are also prime. For instance, the number 9137 is a left-truncatable prime since 9137, 137, 37 and 7 are all prime.

A right-truncatable prime number is similarly defined, but removes a digit from the right. For example, 31193 is a right-truncatable prime since 31193, 3119, 311, 31, 3 are all prime.

A truncatable prime, also known as a two-sided prime, is one that is both left-truncatable and right-truncatable simultaneously. An example of such a prime is 3797.

We will be writing a program to explore these truncatable primes.

As a side note, the property of truncatable is dependent upon the base that the number is represented in. For this program, only worry about base 10.

Analysis

First note that the property of truncatability always produces a chain of numbers that terminate in single digit prime numbers. Therefore we can identify prime numbers by starting at the end of that chain and build numbers by adding digits. That is, we should be able to identify 3797 as a truncatable prime by building it from the right as in 7, 97, 797, then 3797, all the while verifying each step is left-truncatable.

Next note that when building from the right, we can only add odd digits. If we were to add a 0, 2, 4, 6, or 8, the resulting number would be divisible by 2 and thus not prime.

Finally, all of the single digit prime numbers are 2, 3, 5, and 7. These form the basis of our search.

Approach

Based upon the analysis above, we can find truncatable primes by building primes that are right-truncatable by construction, and verify they are left truncatable as we go. This suggest the following recursive algorithm

Build Truncatable Primes(int start)

if (start is not prime)

return

if (start is left truncatable)

found one. print it out

Build Truncatable Primes (start * 10 + 1)

Build Truncatable Primes (start * 10 + 3)

Build Truncatable Primes (start * 10 + 7)

Build Truncatable Primes (start * 10 + 9)

For left-truncatable, consider testing the number 12345. We know that we need to check 12345, 2345, 345, 45, and 5. But since all must be prime, the order they are tested in does not matter. In particular, we can check them in the order 5, 45, 345, 2345, 12345. What is nice about that order is we can get those digits by modding by successive powers of 10. Therefore you can use a loop that starts at 10, and updates by multiplying by 10.

Tips

· Start by writing an is_prime function.

· Next write an is_left_truncatable function.

· Using the modulus operator with powers of 10 can cut off digits from the left side.

· Write the algorithm specified above.

· Start the algorithm with all possible single digit prime numbers.

 Write a brief paper in APA format of 500-1000 words that respond to the following questions with your thoughts, ideas, and comments. Be substantive and clear, and include the tables below to support your findings. Refer to the APA Sample Research Paper as a template for your write up.

A survey was conducted to analyze the debt of individuals in the United States. A researcher obtained this secondary data and ran Chi-Square and Crosstabulation analyses to determine if people who defaulted on loans is associated the level of education they completed. Additionally, the researcher wanted to determine which education level(s) are more likely to default on a loan. The results of his analyses are provided below.

Write the Results section of the paper and present the results using appropriate APA-formatted tables and figures. Include one research question and one set of an aligned null and alternative hypothesis to address the research goals outlined above. Follow all APA conventions and include the proper APA statistical notation. A clustered bar chart comparing the number of people who defaulted or did not default on a loan, for each education level, is included to help the reader visualized the data and should be included in your paper as an APA-formatted figure.

This assignment serves to benchmark competency 2.1: Establish a risk management framework using industry standards for compliance.

3. A paragraph outlining the framework governing the enterprise
4. Major gaps that were found
5. Remediation that is recommended
6. A high-level diagram that represents the current state of the system
7. An equal diagram depicting the proper end state
