Multidomæne

Multidomæne refers to a concept within computer security and user interface design where a system or application operates with or acknowledges multiple distinct domains or contexts simultaneously. This can manifest in various ways, such as a web browser displaying content from different websites, each with its own security domain, or an operating system allowing users to switch between different security contexts or profiles.

The core idea behind multidomæne is the need to isolate and manage different sets of data, permissions, or functionalities. In web browsing, for example, the Same-Origin Policy is a multidomæne security measure that prevents scripts from one origin (domain, protocol, port) from accessing data from another origin. This helps protect users from malicious websites.

In enterprise environments, multidomæne concepts might be applied to allow a single user to access resources belonging to different departments or security classifications through distinct, controlled interfaces or virtual environments. This enables a more flexible and secure approach to managing access to sensitive information. The implementation of multidomæne often involves complex technical solutions to ensure that these distinct domains do not interfere with each other and that security boundaries are maintained.
