Episode 47 — macOS Security Essentials and Hardening

Apple systems may be known for their usability, but they still demand deliberate hardening. This episode explains how macOS implements security through layered controls, from Gatekeeper app verification to the System Integrity Protection (SIP) framework that locks down key system files. You’ll learn how FileVault provides full-disk encryption, how keychains manage stored credentials, and how the T2 or Apple silicon chip enhances hardware trust. The discussion ties these features to exam objectives around endpoint protection and user privilege management.Listeners will also hear how to configure logging, auditing, and patching for visibility and compliance. We discuss how attackers target Mac environments using persistence mechanisms like LaunchAgents and unsigned binaries, and how to detect them through monitoring and configuration management. The episode concludes by emphasizing that macOS security is about understanding defaults—what’s already strong, what needs attention, and how to manage the balance between simplicity and control.
