What do you think about the CHAOS study’s definition of a successful project? Do you think there are better definitions of success besides meeting scope, time, and cost goals?
In today’s world, both government and the private sector are struggling to provide a secure, efficient, timely, and separate means of delivering essential services. As a result, these critical national infrastructure systems remain at risk from potential attacks via the Internet and from Insiders.
The Federal Government is continually increasing capabilities to address cyber risk associated with critical networks and information systems through the proper separation of data and assets. One way of doing this is through the implementation of firewalls.

Instructions
Initial response
Post your primary response to the Module 2 discussion question(s) by 9:59 PM (EST) by Wednesday of Week 4 Module 2. This posting should be at least 350 words. Late responses will receive a zero grade no exceptions (late is considered one (1) minute after 9:59pm EST). Your primary posting can end with a “tag-line” or a related question of your own.
Attacks on our national infrastructure are already happening. And the expectation is that they will continue to increase at an accelerated rate. For this week’s discussion, we’ll cover threats to our nation’s pipelines. To get started, read this article:
After reading the article, start a discussion thread and discuss how the types of threats discussed in the article could impact our economy, and how implementing Diversity and Commonality (as discussed in chapters 4 and 5) could help mitigate these threats.
You must do this following:
1) Create a new thread. As indicated above, discuss how the types of threats discussed in the article referenced above could impact our economy, and how implementing Diversity and Commonality (as discussed in chapters 4 and 5) could help mitigate these threats.
Part 2:
Prior to beginning work on this assignment read Chapters 1, 2, and 9 of your textbook, review the Database Lifecycle (Links to an external site.) and (DBLC) Database Life Cycle (Links to an external site.) online resources, and review any relevant information in this week’s lecture. These sources will be used to support your work in the assignment. It is also recommended that you log in to your virtual lab environment and make sure you can access the Structured Query Language (SQL) server housed there.
Successful database development must appropriately reflect the information system of which the database is a part. In order to ensure that the database captures the needed information for the target information system, database architects must work within a framework known as the Database Development Life Cycle (DBLC). The DBLC includes steps ranging from initial assessment and analysis to operation and maintenance. This assignment will be the first step in the creation of your Week Six Database Design Project.
For this assignment, analyze the user needs laid out in the ISM641 DBLC Scenario in order to facilitate the development of a database life cycle for the project. Within your paper describe the steps of the Database Development Life Cycle as it relates to the ConstructCo needs. Explain the analysis, design, implementation and testing tasks needed to complete each step within the DBLC for ConstructCo. For the conceptual design phase of the development, describe how unstructured data can be converted to structured data. Explain a minimum of two challenges, either business or technical, you might face when implementing the DBLC process and suggest ways in which you would overcome these challenges. Use evidence from your required resources to support your statements.
The final portion of your paper will be a one-page professional memo that will explain the DBLC steps to the ConstructCo executive team. The objective of the memo is to gain buy-in for the database development process in order to ensure successful project implementation. (Information on Writing a Business Memo, as well as a Business Memo Template, and a Sample Business Memo are provided for your convenience.)
