DVC Software Engineering Process Paper and Concept Map
Prior to beginning work on this interactive assignment, read Chapter 9: Software Evolution in the course text.
It is also recommended that you begin reviewing Chapter 9 exercises 9.1 and 9.4, as these exercises will be your homework assignment due later in the week.
In this week’s interactive assignment, you will add to your concept map that you created in Week 4 and further illustrate and make connections among the concepts of software evolution. This week’s section of the concept map is focused on software evolution. In your concept map, illustrate and label each component of software evolution. Show the logical elements of a legacy system and describe their relationships.
In addition to your concept map, you will write a paper in which you will assume an organization has N legacy systems, and you want to assess the quality and business value of these systems. In your paper,
Describe the four clusters of N systems using “quality” versus “business value” coordinates.
Provide a pie chart showing the approximate distribution of costs, based on the available survey by Davidson and Krogstie (2010) in your text.
Explain three different types of software maintenance.
Describe a general model for the reengineering of software process, using a legacy program as input and an improved version of the same program as an output.

Discussions of Security Control Frameworks and Controlling the Uncontrollable
1. When performing a gap analysis, one must have an understanding of the desired future or "to be" state. For cybersecurity focused gap analyses, we frequently use IT security controls as the framework for describing the "to be" (or "should be") state. There are a variety of guidance documents which list and define sets of security controls.If you look at multiple sources, e.g. NIST, SANS, CSIS, you will see that IT controls come in a variety of "flavors". Some sources use the People, Process, and Technology scheme to organize and define controls. Other sources define controls (safeguards) in terms of the phases of information security to which they apply (e.g, Preventive controls, Detective controls, Deterrent controls, Corrective controls (used in the Response or remediation phases)). A third framework which you used in earlier courses (CSIA 413) is "administrative or managerial, operational, and technical" controls.Research and select a control grouping framework then populate the framework with some examples of the actual controls. Provide your rational as to why you selected your framework and identify an industry or industry vertical to which your framework is most applicable.2. What four (4) IT security controls do you find the most important? Why? Do you consider anything related to process or policy a real or actual "safeguard?" Why? Why not? Note: Use NIST SP 800-53 (http://nvlpubs.nist.gov/nistpubs/SpecialPublicatio...) as your source for security controls definitions for this discussion question.

CS 405 SNHU Module 4 C++ in Visual Studio Computer Science Task
Overview
You are a senior software developer on a team of software developers who are responsible for a large banking web application. Your manager has recently learned about the best practice of creating unit tests for software and wants to see a full example of how it works. Another developer on the team started creating a unit test for the std::vector class, and he managed to get the TextFixture and a few tests completed before his vacation started. Your manager is impatient and has asked you to complete the task. He wants to see a number of tests, including positive and negative tests.
Key Concepts
Positive tests prove that functionality works when tested. For example, Test(1+1) = 2.
Negative tests prove that an error or exception happens when provided bad data. For example, Test(5/0) => Divide By Zero.
The following are some essential notes:
The source code has been commented using TODO to explain the detailed rules you must follow.
You are provided the situation to create 13 unit tests, of which 11 are defined for you and 2 you will need to define.
You only need a minimum of 2 negative tests, but can do more.
Test names should reflect the purpose of a test. For example, to test that a number is positive, the test name would be something like EnsureNumberIsPositive.
Do not confuse the C++ assert / static_assert with the Google Test ASSERT and EXCEPT.
When should you use the EXPECT_xxx or ASSERT_xxx macros?
Use ASSERT when failure should terminate processing, such as the reason for the test case.
Use EXPECT when failure should notify, but processing should continue.
There are multiple ways to validate the test results, but each test must explicitly prove the defined condition of the test.
Do not forget that you can leverage capabilities provided by the standard C++ library to help you achieve success.
You will learn to do the following:
Name unit tests correctly
Compile and run a Google unit test fixture
Extend Google unit test fixture with a number of positive and negative tests
Prove the test results
Prompt
Test the existing source code in the test.cpp file using the Google unit testing framework. Include a brief written summary of the process you used, the issues you found, and how you managed the issues.
Specifically, address the following in a static testing summary:
Unit Test Names: Define all unit test names to appropriately reflect the test condition.
Unit Testing: Successfully implement the 13 unit tests, as part of the Google Test fixture; run Google Test ASSERT and EXPECT functionality to prove the tests. Each test you run must explicitly prove the defined condition of the test.
Negative Unit Tests: Complete at least 2 of the unit tests as negative tests that demonstrate capturing the appropriate unit test result based on an expected negative result of the test code.
C/C++ Program Functionality and Best Practices: Demonstrate industry standard best practices, including in-line comments and appropriate naming conventions to enhance readability of code. Develop functional C/C++ code that illustrates a software design pattern approach.
Process Summary: Provide a summary of the debugging that is thorough and systematic, including specific types of bugs, and that accurately describes the corrections.
To complete this assignment, download the test.cpp file and use the Google Test Guide as guidance as you move through the activity. You will use your development environment to complete this activity. Google Test has a number of resources online, including the following:
