Our BGMI (Battlegrounds Mobile India) infrastructure occasionally freezes when traffic surges. I want to put a permanent stop to that by building a preventive DDOS shield that covers every critical touch-point—login, in-game communication, and matchmaking. You will begin with a quick audit of the existing network layout and traffic patterns, then design and deploy a solution that blocks volumetric and application-layer attacks before they can overwhelm the servers. I expect minimal additional latency for legitimate players, clean documentation of every rule or service introduced, and a repeatable playbook I can apply to new nodes as we scale. Deliverables • Security architecture diagram and written rollout plan • Hardened configurations applied to the login, game, a...
