The Five Pillars
The Five Pillars are the five essential areas you must protect to keep your digital life safe: who you are (Identity), the gadgets you use (Devices), how you connect (Network), the software you run (Applications), and the information you keep (Data). Think of it like securing a house: you need to lock the front door, secure the windows, protect the driveway, guard the rooms, and keep your valuables in a safe.
The Five Pillars represent the foundational security domains—Identity, Devices, Network, Applications, and Data—that form the Practical Cyber Knowledge Spine. By addressing these five distinct areas, security professionals ensure a comprehensive defense-in-depth strategy that covers the entire lifecycle of digital assets and interactions.
