Threat Modeling and Risk Assessment
Threat modeling and risk assessment are systematic processes used to identify, evaluate, and prioritize potential security threats and vulnerabilities within a system or organization. Threat modeling focuses on understanding possible attack vectors and adversaries, while risk assessment evaluates the likelihood and impact of these threats. Together, they help organizations implement effective security controls, reduce risks, and safeguard critical assets by proactively addressing weaknesses before they can be exploited.

❓ Frequently Asked Questions
What is threat modeling?
A structured process to identify potential security threats, attacker capabilities, and attack paths so you know where a system might be vulnerable and how to strengthen it.
What is risk assessment?
A systematic evaluation of how likely threats are to occur and how much damage they could cause, used to prioritize security actions.
How do threat modeling and risk assessment relate to each other?
Threat modeling lists possible threats and attack paths; risk assessment estimates their likelihood and impact to guide prioritization and remediation.
What is an attack vector?
A path or method an attacker uses to exploit a vulnerability, such as phishing, software bugs, or misconfigurations.
