🔒 Understanding Operating System Security: Processes, System Calls & Kernel 🔒

Welcome to InfoSecTube! In this episode, we break down the core of OS security — how operating systems control processes, system calls, and the kernel interface. Learn how fork(), exec(), and wait() shape modern UNIX-style process management. Discover user mode vs. kernel mode, trap instructions, and how the OS regains control with timer interrupts and limited direct execution.

Understand the role of the superuser (root) and the importance of security boundaries in multi-user systems.
