Episode 11 — Prevent unapproved execution with allowlisting logic and tightly governed exceptions

This episode explains how application allowlisting reduces attack surface by controlling what is permitted to execute, not just what is blocked after detection. You’ll define allowlisting in practical terms, including path rules, publisher signatures, hashes, and policy scopes that apply differently to servers, endpoints, and privileged admin workstations. For the exam, you’ll focus on the intent: preventing unknown binaries, scripts, and living-off-the-land abuse from running when a user is tricked or a system is partially compromised. We’ll walk through how to design exceptions without undermining the control, including who can request an exception, what evidence is required, how to time-box approvals, and how to review exceptions for removal. Real-world scenarios include urgent business installs, developer toolchains, and break-glass troubleshooting, with guidance on compensating safeguards like monitoring, temporary elevation, and restricted execution contexts.
