Website Shared Responsibility Model

A website shared responsibility model explains who must do which work to keep a site operational and secure. A hosting provider may protect its infrastructure while the site owner remains responsible for published content, permissions, lawful data collection, and commercial decisions. A developer or maintenance contractor may handle application updates, monitoring, and backups, but only to the extent agreed in its service scope.

The responsibilities change with the technology. A managed website builder may patch more of the underlying stack than a self-managed virtual server. Cloud-service providers describe shared security as responsibilities 'of' and 'in' the cloud; for a typical business website, that framework is a starting analogy, not a substitute for the actual contract.

An effective responsibility matrix states the owner, backup owner, escalation route, test frequency, and evidence for tasks such as domain renewal, DNS, vulnerability patching, restores, analytics access, and incident communication. Unassigned tasks are a common practical risk: paying for hosting does not automatically mean every application, plugin, or business process is managed.
