isäntöpohjainen

Isäntäpohjainen, often translated as host-based, refers to a security or management model where security controls, policies, or data are managed and enforced directly on individual endpoints or hosts. This contrasts with network-based approaches that focus on the perimeter or traffic flow. In an isäntäpohjainen system, each device or server is responsible for its own security posture.

This approach typically involves installing security software, such as antivirus, firewalls, or intrusion detection/prevention systems, directly onto the host. Configuration management and policy enforcement are also done on a per-host basis, ensuring that each device adheres to specific security standards. Logging and monitoring are often conducted locally on the host before being aggregated to a central system.

Key advantages of an isäntäpohjainen model include granular control over individual systems, the ability to secure devices regardless of their network location, and detailed insight into the activity on each host. It can be particularly effective for protecting sensitive data directly on the endpoint where it is accessed and processed. However, it can also be resource-intensive, requiring significant management effort to deploy, configure, and maintain security on a large number of individual hosts. Centralized management tools are often employed to mitigate this overhead.
