Topic 2: Computer, Data, and Device Basics

Understanding CPU execution cycles, volatile memory (RAM), persistent storage blocks (SSD/HDD), and network interface traffic.

Exploring OS kernel paradigms, platform-specific security sandboxing architectures, and regular updates.

Managing access control lists (ACLs), read/write/execute variables, and folder group permissions.

Mitigating BadUSB attacks, firmware-level exploits, hardware keyloggers, and infected auto-run file trees.

Applying initial secure installation guidelines, disabling unnecessary legacy protocols, and ensuring drive lockup during sleep states.

How do platform sandboxes protect modern systems?

They restrict applications to isolated execution zones, blocking unauthorized reads or writes to system files or other application memory blocks.
