Threat Model
Lexicon Core Definition
A threat model is a structured framework for identifying, analyzing, and prioritizing the specific security threats most relevant to your situation, enabling you to implement appropriate defenses rather than trying to protect against every theoretically possible attack.
Analysis Breakdown
Frequent Queries
Why do I need a threat model instead of just using maximum security for everything?
Maximum security for everything is impractical and often counterproductive. Extremely high security typically requires significant time, expense, and complexity that may exceed the value of what you're protecting. Someone holding a few hundred dollars doesn't need the same security infrastructure as someone holding millions. Threat modeling helps you implement appropriate security—enough to protect against realistic threats without wasting resources or creating such complex processes that you make mistakes or avoid using security measures. Good security is sustainable security matched to your actual risks, not theoretical perfection that's impossible to maintain. Over-engineering security can be as problematic as under-engineering it, leading to security fatigue and ultimately weaker protection.
How do I create a threat model for my cryptocurrency holdings?
Start by answering five key questions: First, what am I protecting (how much value, what assets)? Second, who might attack me (opportunistic scammers, targeted attackers, physical thieves)? Third, how would they attack (phishing, malware, social engineering, physical theft)? Fourth, how likely is each attack given my situation? Fifth, what would I lose if each attack succeeded? Then prioritize defenses against your highest-probability, highest-impact threats. Small holders focus on phishing and basic device security. Medium holders add hardware wallets and secure backups. Large or visible holders implement comprehensive operational security. Revisit quarterly or when circumstances change. The goal is matching security investments to realistic threats you actually face.
Does my threat model need to change over time?
Yes, your threat model should evolve as your circumstances change. As holdings grow, you become a more attractive target requiring stronger security. As you become more public about cryptocurrency involvement, you face increased social engineering and targeted attack risks. As you gain technical sophistication, you can implement more advanced defenses. As new attack types emerge, you may need to adapt defenses. Review your threat model quarterly or after significant changes: large holdings increases, public speaking or writing about crypto, security incident attempts, or major lifestyle changes. Security appropriate for your situation last year may be insufficient today. Regular reviews ensure your defenses remain matched to current threats.
Calibration Check
Everyone faces the same cryptocurrency security threats, so everyone needs the same security measures
Security threats vary dramatically based on individual circumstances. Someone holding small amounts primarily faces opportunistic phishing and basic scams. Someone with medium holdings faces more sophisticated phishing plus physical theft risks. Someone with large public holdings faces targeted social engineering, sophisticated attacks, potential physical threats, and enhanced scrutiny from criminals who specifically research high-value targets. Your job, living situation, technical skills, public visibility, and usage patterns all affect your specific threat landscape. Effective security requires understanding your unique threats rather than implementing generic protections that may not match your actual risks. A one-size-fits-all security approach wastes resources on irrelevant threats while potentially missing critical vulnerabilities specific to your situation.
Creating a threat model is too complex and technical for regular users
Basic threat modeling is simply thinking honestly about your situation using common sense. You don't need cybersecurity expertise—just answer straightforward questions: How much am I holding? Would losing it devastate me? Am I public about crypto involvement? Do I use public WiFi? Do I share devices? What would be the easiest way for someone to steal from me given my habits? This practical thinking, not technical analysis, is sufficient for most users to identify their primary threats and implement appropriate defenses. Simple threat models like identifying that you're vulnerable to phishing because you use email frequently is valuable insight that guides focusing on URL verification and bookmark usage. The process doesn't require technical expertise, just honest self-assessment.
Once I create a threat model, my security planning is complete
Threat modeling is an ongoing process, not a one-time exercise. Your threat landscape changes as your holdings grow, your involvement becomes more public, new attack techniques emerge, your technical skills improve, or your life circumstances shift. What was appropriate security six months ago may be insufficient or excessive today. Additionally, threat modeling should lead to action—implementing appropriate defenses against identified threats, testing those defenses periodically, and adjusting as you learn what works. Threat modeling is a continuous cycle of assessment, implementation, testing, and refinement that makes your security increasingly appropriate to your evolving situation. Regular quarterly reviews ensure your defenses remain matched to current threats and circumstances.
