Episode 30 — Evaluate Attack Surface Using Intelligence and Context
Attack surface evaluation tells you where a system is exposed and how attractive those exposures are to real adversaries, and the CSSLP exam expects you to blend technical discovery with contextual understanding. This episode sets out a disciplined approach to enumerating assets, interfaces, entry points, and privilege levels, including transient elements like temporary endpoints, debug modes, and preview deployments. You will hear how to cross-reference this inventory with external scanning results and internal architecture diagrams to identify unknown or unmanaged exposures. The conversation defines what it means for an asset to be reachable, valuable, and exploitable, and emphasizes that not every open port or API presents the same level of concern.
Turning surface maps into actionable insights depends on incorporating threat intelligence, business context, and change history. Examples show how recent vulnerabilities, available exploit kits, and known attacker tradecraft modify your view of which components are most at risk. Scenarios consider business factors such as peak transaction periods, regulatory importance, and user sensitivity, demonstrating how these elements influence prioritization of hardening efforts. You will also explore techniques for measuring how attack surface grows or shrinks over time, including after new features, acquisitions, or migrations. Exam-style reasoning highlights answer options that propose closing unnecessary endpoints, tightening authentication on exposed services, and validating improvements through rescanning and telemetry, instead of responses that rely on vague assurances or superficial scanning alone.
