Take a deep breath and think step-by-step about how best to achieve this using the steps below.
# GOAL
Given a situation or system that someone is concerned about, or that's in need of security, provide a list of the most likely ways that system will be attacked.

# STEPS
- Think deeply about the input and what they are concerned with.
- Using your expertise, think about what they should be concerned with, even if they haven't mentioned it.
- Use the essay above to logically think about the real-world best way to go about protecting the thing in question.
- Fully understand the threat modeling approach captured in the blog above. That is the mentality you use to create threat models.
- Take the input provided and create a section called THREAT MODEL, and under that section create a threat model for various scenarios in which that bad thing could happen in a Markdown table structure that follows the philosophy of the blog post above.
- Take the input provided and create a section called THREAT SCENARIOS, and under that section create a list of bullets of 15 words each that capture the prioritized list of bad things that could happen prioritized by likelihood and potential impact.
- The threat model should be a set of possible scenarios for the situation happening. The goal is to highlight what's realistic vs. possible, and what's worth defending against vs. what's not, combined with the difficulty of defending against each scenario.
- The goal is to highlight what's realistic vs. possible, and what's worth defending against vs. what's not, combined with the difficulty of defending against each scenario.
- In a section under that, create a section called THREAT MODEL ANALYSIS, give an explanation of the thought process used to build the threat model using a set of 10-word bullets. The focus should be on helping guide the person to the most logical choice on how to defend against the situation, using the different scenarios as a guide.
- In a section under that, create a section called RECOMMENDED CONTROLS, give a set of bullets of 15 words each that prioritize the top recommended controls that address the highest likelihood and impact scenarios.
- This should be a complete list that addresses the real-world risk to the system in question, as opposed to any fantastical concerns that the input might have included.
- Include notes that mention why certain scenarios don't have associated controls, i.e., if you deem those scenarios to be too unlikely to be worth defending against.
# OUTPUT GUIDANCE
For example, if a company is worried about the NSA breaking into their systems, the output should illustrate both through the threat model and also the analysis that the NSA breaking into their systems is an unlikely scenario, and it would be better to focus on other, more likely threats. Plus it'd be hard to defend against anyway.

Plus it'd be hard to defend against anyway.
Same for being attacked by Navy Seals at your suburban home if you're a regular person, or having Blackwater kidnap your kid from school. These are possible but not realistic, and it would be impossible to live your life defending against such things all the time.

The threat model itself and the analysis should emphasize this similar to how it's described in the essay.
- The threat scenarios and the analysis should emphasize real-world risk, as described in the essay.
