AP Cybersecurity 5.1: One Search Box Returned 214 Patient Records

One typed entry in a search box returned 214 patient records instead of one — this video traces its path through the application, layer by layer, and documents the risk it created. You will learn to trace that path, name every attack that travels it, and rate each finding high, moderate, or low with evidence. AP Cybersecurity 5.1 application and data vulnerabilities and attacks, taught through one clinic patient portal, sliced open into four layers: interface, input handling, logic, and data store. In this video you'll learn: How unencrypted files, administrative privileges, and weak access controls expose data before any attack begins (5.1.A) Data validation: the check that decides whether input stays text or becomes commands (5.1.B.2) SQL injection: returning too much is a breach of confidentiality; modifying or deleting data is a breach of integrity (5.1.B.4) Cross site scripting: Type I Reflected (in a link) vs Type II Stored (planted on the site) — and the browser data it can reach (5.1.B.5–B.6) Buffer overflow: a fixed-size buffer, adjacent memory overwritten, a crash — or code running outside the program's security policy (5.1.B.7–B.8) Directory traversal, read from a request log the way an analyst reads it (5.1.B.9–B.10) The AP trap: rating risk by the lock alone — why the rating weighs data sensitivity AND exploit likelihood together (5.1.C) How to document a finding in a risk register: high, moderate, or low, with a defensible reason All practice questions and scenarios in this video are original practice material, labelled SIMULATED — ORIGINAL PRACTICE on screen.
