Episode 8 — Threats, Vulnerabilities, and Exposure Basics

Here we untangle three terms that often get blended in conversation and on exams. The episode defines a threat as an agent or event with intent or capability to cause harm, a vulnerability as a weakness that can be exploited, and exposure as the degree to which an asset is open to potential harm. You’ll hear how these concepts combine into practical risk stories and how wording in questions signals which element you’re being asked to analyze. We also discuss common sources—configuration gaps, weak authentication, unpatched software, and insecure defaults—so you can quickly categorize what you’re seeing.
We then translate definitions into scenarios: a misconfigured S3 bucket, a legacy VPN with outdated ciphers, a public web form vulnerable to injection, or an endpoint lacking application control. For each, we show how to describe the threat actor, name the vulnerability precisely, and estimate exposure based on access paths and blast radius. You’ll leave with a checklist for distinguishing root cause from symptom, plus tips for prioritizing mitigations that meaningfully reduce opportunity for exploitation.
