Linux vs. Windows vs. macOS: Where Security Actually Differs

People love to ask which operating system is the most secure. That's the wrong shape of question. Each one is designed for a different job, and that shapes how it gets attacked.

This episode clears up what Linux actually is, how it compares to Windows and macOS, and why the differences matter for security. It starts by explaining why Linux isn't one product but a family of systems built around a shared kernel, then covers how each OS handles permissions, software installation, and administrator access differently. The episode walks through why Windows attracts commodity malware at scale, why macOS trades flexibility for Apple's guardrails, and why Linux incidents usually start not with a dramatic virus but with quiet exposure: an open SSH service, default credentials, or a skipped patch. It busts three common myths (Linux doesn't get malware, open source means audited, macOS and Linux are the same thing) and closes with a five-step starter kit covering patching, attack surface reduction, least privilege, trusted software sources, and recovery planning.

Whether you're choosing an OS for your team, managing Linux servers for the first time, or just curious why your security team cares so much about configurations, Plaintext with Rich sorts it out.
