Game streaming delivers a game from a remote system while the local device handles input, video output, and network communication. The heavy rendering and game logic run on a server, PC, or cloud host, so the client can be comparatively weak and still play demanding software.
In cyber security, the model matters because it shifts trust and risk to the network and remote platform. Attackers may target streaming accounts, session tokens, or the software that relays input and video. Poorly secured clients can leak credentials, expose stored sessions, or be abused as a foothold into home networks. Defenders use the same architecture for controlled access, centralized patching, and limited local processing, but they must harden authentication, encrypt traffic, and monitor for hijacking or man-in-the-middle tampering. Game streaming is therefore not just a performance trick; it is a security boundary that moves with the service.
