Thought I had this cold but mid-answer I started second-guessing myself on where threat ends and risk begins.
Define each term clearly and then explain their relationships using a concrete example, such as a SQL injection vulnerability. Emphasize that risk is a function of threat, vulnerability, and impact, and that as an engineer you prioritize based on risk.
Pro tip: Tie your answer to Amazon's leadership principles, like Customer Obsession and Dive Deep, by explaining how you assess risk to prioritize fixes that protect customers. Show that you think beyond definitions to practical decision-making.
A vulnerability is a weakness or flaw in a system that can be exploited by a threat. For example, unvalidated input in a web application.
A threat is any circumstance or event with the potential to exploit a vulnerability and cause harm. This includes malicious actors, natural disasters, or accidental errors.
Risk is the potential for loss or damage when a threat exploits a vulnerability. It is often calculated as the likelihood of an event multiplied by its impact.
Use a concrete scenario to show how the three concepts interact. For instance, a SQL injection vulnerability, a hacker threat, and the risk of data breach.
Discuss how you use this understanding to prioritize security efforts, such as mitigating high-risk vulnerabilities first and implementing defense in depth.
