># Guide to Determining Your Threat Model
>
> Creating a solid threat model is an essential step in improving your operations security (OPSEC). It helps you identify potential threats, assess their impact, and prioritize your defenses. Here’s a step-by-step guide to help you develop your own threat model.
>
> ---
>
> #### 1. Define Your Assets
> First, list the things you want to protect. These might include:
>
> - **Personal Information:** Name, address, phone number, Social Security number, etc.
> - **Financial Information:** Bank account details, credit card numbers, financial records.
> - **Digital Assets:** Emails, social media accounts, documents, photos.
> - **Physical Assets:** Home, devices (computers, smartphones, etc.).
>
> #### 2. Identify Potential Threats
> Next, think about who or what could pose a threat to your assets. Possible threats include:
>
> - **Hackers:** Individuals or groups looking to steal data or money.
> - **Government Agencies:** Law enforcement or intelligence agencies conducting surveillance.
> - **Corporations:** Companies collecting data for marketing or other purposes.
> - **Insiders:** Employees or contractors who might misuse their access.
> - **Physical Threats:** Burglars or thieves aiming to physically access your assets.
>
> #### 3. Assess Your Vulnerabilities
> Identify weaknesses that these threats could exploit. Consider:
>
> - **Technical Vulnerabilities:** Unpatched software, weak passwords, outdated systems.
> - **Behavioral Vulnerabilities:** Poor security habits, lack of awareness.
> - **Physical Vulnerabilities:** Insecure physical locations, lack of physical security measures.
>
> #### 4. Determine the Potential Impact
> Think about the consequences if your assets were compromised. Ask yourself:
>
> - **How critical is the asset?**
> - **What would happen if it were accessed, stolen, or damaged?**
> - **Could compromising this asset lead to further vulnerabilities?**
>
> #### 5. Prioritize Your Risks
> Based on your assessment, rank your risks by considering:
>
> - **Likelihood:** How probable is it that a specific threat will exploit a particular vulnerability?
> - **Impact:** How severe would the consequences be if the threat succeeded?
>
> #### 6. Develop Mitigation Strategies
> Create a plan to address the most critical risks. Strategies might include:
>
> - **Technical Measures:**
> - Use strong, unique passwords and enable two-factor authentication.
> - Keep your software and systems up to date with the latest security patches.
> - Use encryption to protect sensitive data.
>
> - **Behavioral Measures:**
> - Be cautious with sharing personal information online.
> - Stay informed about common scams and phishing tactics.
> - Regularly review your privacy settings on social media and other platforms.
>
> - **Physical Measures:**
> - Secure your devices with locks and use physical security measures for your home or office.
> - Store sensitive documents in a safe place.
> - Be mindful of your surroundings and use privacy screens in public places.
>
> #### 7. Continuously Review and Update
> Your threat model isn’t a one-time project. Review and update it regularly as your situation changes or new threats emerge.

> # Example Threat Model
>
> 1. **Assets:**
> - Personal Information (e.g., SSN, address)
> - Financial Information (e.g., bank accounts)
> - Digital Assets (e.g., emails, social media)
> - Physical Assets (e.g., laptop, phone)
>
> 2. **Threats:**
> - Hackers (e.g., phishing attacks)
> - Government Agencies (e.g., surveillance)
> - Corporations (e.g., data collection)
> - Insiders (e.g., disgruntled employees)
> - Physical Threats (e.g., theft)
>
> 3. **Vulnerabilities:**
> - Weak passwords
> - Outdated software
> - Sharing too much information online
> - Insecure physical locations
>
> 4. **Potential Impact:**
> - Identity theft
> - Financial loss
> - Loss of privacy
> - Compromise of additional accounts
>
> 5. **Prioritize Risks:**
> - High Likelihood/High Impact: Weak passwords leading to account compromise.
> - Low Likelihood/High Impact: Government surveillance leading to loss of privacy.
>
> 6. **Mitigation Strategies:**
> - Use a password manager and enable two-factor authentication.
> - Regularly update all software and devices.
> - Limit the amount of personal information shared online.
> - Use a home security system and lock devices.
No, it should delete all system files. Those people don’t deserve a computer.
