Embarking on this task lets you discern the perimeters of your information empire. What encloses your data, and what vulnerabilities lay along its border? These boundaries define what falls under your purview for protection and what might be influenced by external threats. Grasping this allows strategizing for security nuances. Ah, but where do potential pitfalls lurk? Old system documentation, perhaps, or convoluted network diagrams. With careful mapping and energized focus, you'll pinpoint these boundaries effectively.
