Kaitseskeem

Kaitseskeem, often translated as "protection scheme" or "security diagram," is a conceptual tool used to visually represent the layers of security measures implemented to protect a system, asset, or information. It illustrates how different components and their associated defenses work together to prevent unauthorized access, mitigate threats, and ensure the integrity and availability of what is being protected.

A typical kaitseskeem would depict concentric circles or distinct zones, with the most critical or sensitive elements at the center and progressively less sensitive elements or the external environment further out. Each layer represents a different type of security control, which can be physical, technical, or procedural. Physical barriers might include walls, fences, or locked doors. Technical controls could involve firewalls, encryption, intrusion detection systems, and access control lists. Procedural measures often encompass security policies, user training, background checks, and incident response plans.

The purpose of a kaitseskeem is to provide a clear and easily understandable overview of the overall security posture. It helps in identifying potential weaknesses or gaps in the defense strategy by highlighting how a breach in one layer might be contained or detected by subsequent layers. It also facilitates communication about security requirements and strategies among stakeholders, including security professionals, management, and users. By visualizing the security architecture, organizations can better allocate resources, prioritize security investments, and ensure a comprehensive approach to risk management.
