 Instructions
You must use the template I provided for this assignment since it will make it a lot easier for you. Failure to do so will result in a return of your paper for you to redo, a reduction in points, or both.
The first assignment has three parts. 
The first part involves picking something you found interesting from weeks one and two, exploring it beyond the readings, and expanding on it in a paper. This section of your paper needs to be at least three pages long and cannot be about something you wrote directly about in a forum.
The second part involves picking one of the critical infrastructures you learned in week three and writing about it using the six guidelines below. You cannot write about the critical infrastructure you wrote about in the forum.
The third part involves picking one of the critical infrastructures that you learned about in week four and writing about it using the six guidelines below. You cannot write about the critical infrastructure you wrote about in the forum.
It is up to you to decide what will be the most interesting for you! 
You need to use the following outline for each of the two critical infrastructures:
Provide a Hypothetical Threat (cyber, natural disaster, or physical)
Brief background on the Critical Infrastructure as it relates to National Security
Elaborate on the known Risks/Threats/Hazards/Vulnerabilities from the Hypothetical Threat
Explain how damage from the Hypothetical Threat could impact the Dependencies/Interdependencies between critical infrastructure sectors
Existing Resiliency related to the Continuity of Operations
Consider how to Minimize Disruption that improves First Responder Safety. 
Technical Requirements
Write at least seven pages, per the guidance above, and include the title page, an abstract, and a reference page (these last three items are not part of the total page count).
Scholarly and credible references should be used. A good rule of thumb is at least two sources per content page.
Type in Times New Roman, 12 point, and double-spaced.
Students will follow the current APA Style (7th Edition) as the sole citation and reference style used in written work submitted as part of coursework. 
Points will be deducted for the use of Wikipedia or encyclopedic-type sources. It is highly advised to utilize books, peer-reviewed journals, articles, archived documents, etc.
All submissions will be graded using the assignment rubric.

Provide a reflection of at least 500 words (or 2 pages double spaced) of how the knowledge, skills, or theories of this course have been applied, or could be applied, in a practical manner to your current work environment. If you are not currently working, share times when you have or could observe these theories and knowledge could be applied to an employment opportunity in your field of study.

5. Document how five (5) or more components and measures in the network architecture, as
well as host-based measures, address the security threats from the previous step. The
components could be a combination of software or hardware in nature – such as firewalls,
IDS/IPS, routers, switches, anti-virus/malware software, full-disk encryption (FDE) and
encryption in transit, remote device management software, etc.
6. Describe in three (3) or more paragraphs the specific security threats regarding the
specialty topic you chose. These are in addition to those from step 4.
7. Describe in three (3) or more paragraphs the security controls (and their rationale for
inclusion) that you will implement to mitigate against the security threats of the chosen
specialty.
8. Beyond the network design, what additional procedural/governance measures do you
recommend to address security concerns (e.g., training, procedures, policies)? Describe in
two (2) or more paragraphs at least one measure.
9. Describe in one or more paragraphs how biblical principles come to bear with your
proposed design and approach. Include specific scriptural references.
