3 Terms and definitions

The following terms and definitions apply to this document.

3.1 cyberspace

The interconnected digital environment consisting of the networks, services, systems, people, processes, organizations, and things that reside in or traverse the digital environment.

Note. Cyberspace mainly relies on information and communication technology infrastructure carriers such as the Internet, telecommunications networks, and various control systems and equipment.

[Source. ISO /IEC TS27100 2020, 3.5, modified]

3.2 cyberspaceresource

In cyberspace (3.1), targets that can be detected and sensed using network measurement methods.

Examples. infrastructure, application services, data resources, etc.

3.3 [Source. GB/T 30170-2013, 4.10, modified]

A set of mathematical rules for assigning coordinates to elements of cyberspace resources (3.2).

Note. This refers to the positioning reference system for cyberspace resource elements.

3.4 cyberspacemap

Based on the cyberspace coordinate system (3.3), according to certain drawing rules, use mapping methods to express the location of cyberspace resources (3.2) tools to store and display information about the device and its attributes.

3.5 Cyberspace-timedatum

The time system and corresponding parameters used to describe the time when an event occurs in cyberspace, as well as the coordinate system used to describe the location of cyberspace resources.

Definition of standard system and corresponding parameters.

Note. It includes cyberspace time reference and space reference. Cyberspace time reference usually includes time origin, advancement mode, accuracy and length, etc.

The space reference usually includes the origin, basis vectors and scale.

3.6

Based on the cyberspace coordinate system (3.3), with the cyberspace map (3.4) as the goal, in the unified cyberspace time and space reference (3.5) and
