In a Check Point Multi-Domain Security Management environment, the management database is logically segregated into four primary domains to organize different types of data. These domains are:

System Domain: Contains data about the Multi-Domain Server itself, including global administrators, GUI clients, and licenses.

User Domain: Contains definitions for users and user groups.

Global Domain: Contains global objects, policies, and settings that can be assigned to and shared among multiple individual domains.

Log Domain: Contains the log database, which is managed by the Multi-Domain Log Server (MLM) and consolidates logs from all managed domains.

A. "Local" refers to a specific customer domain, not a main database type, and "VPN" is a feature configuration, not a database domain.

B. "Event" is a type of record stored within the Log domain, not a separate top-level database domain itself.

D. "Host" and "Network" are types of network objects that are stored within other domains (like the Global or a local domain), not main database domains.

This section details the architecture, explaining: "The Multi-Domain Server stores data about the Multi-Domain Server itself, administrators, and licenses in the System Domain." and "The Global Domain contains global objects, policies, and settings that you can assign to some or all Domains."

2. Check Point R81.20 Multi-Domain Security Management Administration Guide, Chapter 2: "Multi-Domain Security Management Architecture", Page 22. This page describes the Multi-Domain Log Server, which hosts the log database for all domains, effectively representing the Log Domain.

3. Check Point R81.20 CLI Reference Guide, Page 687. The mdsbackup command description implicitly confirms these domains by having flags and procedures to back up system data, global policies, and logs separately, reflecting their distinct nature. The management of users is also a distinct function, representing the User Domain.
