In cybersecurity, a concentric pattern refers to a method of structuring security controls or network defenses in layered, ring-like formations around critical assets. This approach mimics the concept of wall stacking, where each security layer provides additional protection, making it harder for attackers to reach the core systems. The concentric pattern is often used in defense-in-depth strategies, ensuring that even if one layer is breached, subsequent layers continue to safeguard sensitive data. This pattern is visually and conceptually similar to expanding rings or shapes, effectively compartmentalizing risks and enhancing overall network resilience.
