Overview

This hands-on lab provides comprehensive practice in implementing secure data disposal and sanitization procedures—critical skills for IT professionals and CompTIA A+ certification candidates. Covering objectives from the 220-1202 exam, you'll develop proficiency in various data destruction methods, verification techniques, and compliance requirements that ensure complete data removal from storage devices.

Through guided exercises, you'll master essential data disposal practices including data overwriting, secure file deletion, physical device destruction, sanitization verification, and regulatory compliance procedures. These skills are fundamental for protecting sensitive information, maintaining privacy compliance, and preventing data breaches through improper disposal of storage media and computing devices.
