Discussion: Part 1. In your own words, construct an overview of the critical infrastructure sector you choose for this discussion based on the ones that we are reading about this week. 
Part 2. Examine at least three of the following:
Unique aspects as they relate to national security
Risks/threats/hazards/vulnerabilities related to national security

Potential countermeasures/mitigations related to the continuity of operations
Minimizing disruption and improving first responder safety
Cross-sector dependencies/interdependencies 
Part 3. Give your opinion on how either a physical attack, a cyber event, or a natural disaster could impact critical infrastructure (just discuss one of these, not all three).
