A distribution model is the way software is delivered to users and how the platform or marketplace behind it makes money. Common models include direct downloads, app stores, subscriptions, commissions, and per-install fees. The model affects who controls publishing, what checks are applied, and how updates reach devices.
In cyber security, the distribution model matters because it shapes trust and attack surface. A tightly controlled marketplace can block malicious apps, enforce code signing, and speed up revocation, while a looser model can make it easier for attackers to hide trojanized or fake software in legitimate-looking channels. Attackers also abuse monetization rules by building adware, scareware, or fraudulent apps that exploit platform incentives. Defenders look at the distribution model when assessing supply-chain risk, deciding whether to allow sideloading, and planning how to verify software integrity before installation.
