			In information security, a [[Security domain]] refers to a distinct area within an organization's IT infrastructure that is protected by specific security policies, controls, and boundaries. It serves as a framework for managing access, enforcing compliance, and isolating systems to mitigate risks. The concept is widely used in cybersecurity to segment networks, applications, and data, ensuring that sensitive resources are only accessible to authorized users and systems.

			{{H2\|Definition}}
	https://archive.is/wip/fwXEf
			A [[Security domain]] is a logical or physical grouping of systems, users, or data that share common security requirements and are governed by unified access control mechanisms. It is often defined by organizational policies, regulatory standards, or technical architectures. For example, a financial institution might establish separate [[Security domain]]s for customer data, internal communications, and public-facing services to apply tailored security measures.

			{{H2\|Key Components}}
			The structure of a [[Security domain]] typically includes:
			- Authentication mechanisms: Verifying user identity through passwords, biometrics, or multi-factor authentication.
			- Authorization policies: Defining what resources users or systems can access based on roles or permissions.
			- Access control lists (ACLs): Specifying which entities are permitted or denied access to particular assets.
			- Network segmentation: Isolating [[Security domain]]s using firewalls, virtual local area networks (VLANs), or software-defined networking (SDN).

			{{H2\|Role in Information Security}}
			[[Security domain]]s play a critical role in reducing the attack surface of an organization's infrastructure. By compartmentalizing systems, breaches in one [[Security domain]] are less likely to compromise others. This principle is central to strategies like zero trust architecture, where every access request is authenticated and authorized regardless of its origin.

			{{H2\|Applications and Examples}}
			[[Security domain]]s are implemented in various contexts, including:
			- Enterprise networks: Separating administrative, user, and guest networks.
			- Cloud computing: Isolating tenant environments in multi-tenant platforms.
			- Industrial control systems: Protecting critical infrastructure from unauthorized access.
			- Healthcare systems: Ensuring compliance with regulations like HIPAA by segmenting patient data.
