Management opsawg Internet-Draft This memo discusses and defines a framework for cyberspace resource property description, which is suitable for the unified classification organization and description of multi-source network resource measurement information. Now, there is no unified description framework for network resource property. The objective of this draft is to establish a general model based on cyberspace identification reference, and implement the reuse of survey data in different users and occasions. Then discuss the basic methodology and propose a less mature framework for further complement and improvement

Network space measurement is based on certain methods, techniques and standards. It uses software or hardware tools to test the composition, behavior and development of cyberspace by testing multiple indicators that characterize the state, property and relationships of various layers of cyberspace. The range of measurement can be local to the network space or global. The objects to be measured include the composition, structure, property, behavior, characteristics, laws and trends of the network space. The information obtained by measurement is a kind of typical big data. The content is diverse in format, complex in structure and rapid in change. It is difficult to understand, interact with, and disseminate the information. Given that network measurement data may be used by many people other than producers. It is usually produced by an individual or organization and used by others or organizations. Building a unified entity encoding rule enables people or organizations that are less familiar with each other to better share data and use the data appropriately. As web measurement data producers and users process more and more data, appropriate textual data can provide them with rich information about the data, enabling them to better manage, store, share, update and reuse data products. This memo can support the integration and management of surveying and mapping information across departments, cross-domains, time space, multi-source and multi-scale networks through the unified description of network space property. It can be used as cyberspace management in the future. It adopts a markup language RDF for describing network resource property, and focuses on the classification and coding rules of network measurement elements and their expansion methods.

In this memo, individuals represent the objects of interest in the field of network mapping space, and OWL does not use the Unique Name Assumption. It must clearly indicate whether individuals are identical, otherwise their relationship is unclear. Note: Individuals are sometimes referred to as Instances.

Properties are binary relationships between individuals. In the description logic, the concept of a Role is represented. Properties can be divided into the following categories: Functional property Functional property can only be connected to one individual. Inverse Functional Property The inverse functional property is that for a given individual, only at most one individual can be connected through this property. That is, the inverse property of this property is a functional property. Inverse Property The inverse property uses only one property name as a parameter, indicating the inversion of the relationship. Transitive Property Transitive property means that the property can be passed. Object Property The Object property represents the relationship between instances of two classes. Datatype Property Connect individual and XML Schema data type values or RDF literals, Datatype property cannot be passed, symmetric, or inverse functional.

Cyberspace is a virtual and real space where human beings use information facilities to construct and realize the information interaction, and then influence human thoughts and behaviors. It relies on the carrier of information and communication technology infrastructure carriers such as Internet, telecommunication networks, and various control systems and devices. In cyberspace, the use of cyberspace means to detect and perceive entities, including the Internet, telecommunications networks, industrial control networks and other types of network resources. Specifically, cyberspace resources include physical equipment such as network infrastructure and network access; information resources and network services such as audio, video, websites and text data; virtual characters, various IP-based telecommunication network equipment and industrial control systems, etc. The feature is an abstract representation of an entity. Note: Features can appear as types or as instances. When expressing only one meaning, you should use a feature type or a feature instance.A single cyberspace resource object existing in cyberspace is a specific unit of cyberspace resource feature, and it is also the smallest component of the corresponding feature types, and can be represented by specific symbols.

RDF: Resource Description Framework RDFS: Resource Description Framework Schema XML: Extensible Markup Language OWL: Ontology Web Language URI: Uniform Resource Identifier DTD: Document Type Definition IDL: Interface Description Language OCL: Object Constraint Language

The following sections highlight some of the most common framework for network resource property description use case scenarios and are in no way exhaustive.

The traditional search method mainly uses keyword matching to realize the retrieval of information. Therefore, it is difficult for the user to simply use the keyword or keyword string to retrieve the content that he really needs, and the natural language changes with time, region or field. The same concept can be expressed in different language expressions. For the same concept retrieval, different users may use different keywords to query, resulting in a large amount of irrelevant information being returned to the user. Intelligent semantic search based on framework for network resource property description is an advanced form of information retrieval, which can provide users with search results in an accurate and concise natural language. When the user initiates the query, the search engine will provides unique identities for each resource, map to parse and reason the keywords of the user query, and then map it to one or a set of concepts, and then according to the concept level in the framework.

There are many elements involved in cyber security. These elements often play a role in the attack threat. According to the order of context, the layers are progressive, and finally reflect the macro network security situation. The purpose of each element is different, and the network security situation process can be divided into several situational segments. Various situational elements are extracted through network security events. Network security situational awareness based on framework for network resource property description can be regarded as a specific situational segment. Through the structure of the security situational, the role of various situational elements is hierarchically displayed, enabling managers to grasp the current network security more deeply and accurately.

Network viruses and worms themselves are also a kind of network resources. With the deepening of network opening and complexity, network viruses and worms are evolving constantly, and the characteristics of diversity and spatial discretization are increasing, resulting in a great hidden danger of network security. The framework for network resources categorization can locate the network resources more accurately and distinguish the benign or malignant network resources, study the process of virus evolution and the possible effects according to the attached attributes , and provide a clearer way to safeguard the operation of network space security, such as anti virus, antivirus and so on.

The attribute description should conform to the basic organizational rules of cyberspace resource mapping information. The selection of attribute classification perspective should meet the integration requirements of multi-source cyberspace resource mapping information, and fully take into account the traditional information classification system in various fields, thus covering network mapping information at various levels and fields.

The methodology of Attribute description should be designed with good compatibility and can cover the requirements of the attribute representation of network measuring and mapping feature of different scales, different properties and different types. The attribute categorization system should correctly reflect the measuring and mapping feature and the vertical and horizontal architecture attributes. The level of information categorization and grading should be clear and reasonable. The same perspective should be adopted for the categorization of objects at the same level.

The design of attribute categorization and description should meet the uniqueness of the measuring and mapping feature attributes of cyberspace resources in the same mapping system, in which the values and units of the physical domain, logical domain and cognitive domain attributes of entities should be consistent with the national and international standards in related fields. When the scale of resources and attributes in cyberspace is modified and redirected, the description of resource attributes and the relationship between resources and attributes should be stable and semantically consistent.

The attribute description, meta property description, resource-attribute relationship description and attribute-attribute relationship description of cyberspace resources are able to perfect and expand when facing the future development of cyberspace, multi-domain information integration and sharing, mapping of unknown resources and user requirements in different fields.

In this memo, the attributes of cyberspace resources are described by RDF resource description framework, and metadata is described as a data model through XML syntax and RDFS. The basic RDF specification only defines the rules, and does not define the vocabularies for describing resources. It should be refined for practical application in different fields. RDF uses Web identifiers (URI) to identify things, and attributes and attribute values to describe resources, allowing RDF to represent one or more simple statements about resources as a graph of nodes and arcs, where nodes represent resource and attribute values and arcs represent attributes. The RDF description for the cyberspace resource attribute consists of a file, resource description, and statement three-level structure, which is serialized by RDF/XML syntax. A file can contain multiple resource descriptions, and a resource description can contain multiple statements, a statement can be expressed as a triplet composed of {subject, predicate, object} in natural language. In the cyberspace resource and the attribute description, the cyberspace resource entity is corresponding to the subject in the triplet, the cyberspace attribute type is corresponding to the predicate in the triplet, and the attribute value is corresponding to the object in the triplet, which constitute the{cyberspace resource entity, cyberspace attribute type, attribute value} triplet can accurately and unambiguously record and describe all the information obtained during the measuring and mapping process.

The association rules of attributes represent the internal relations between attributes, and the possible associations or relations between things can be found behind the data. Unsupervised machine learning methods commonly found in data mining can be used for knowledge discovery and building knowledge maps. In this memo, various attribute association operations are defined: alias relationship, synonym relationship, ownership relationship, and aggregation relationship.

According to the state, structure and behavior characteristics of resources at different levels in cyberspace, this memo divides the properties of resources in cyberspace into four categories, namely physical domain, logical domain, cognitive domain and social domain, which are respectively used to describe the explicit and partial implicit characteristics of resources at corresponding levels. In addition to representing the properties of cyberspace resources, the memo also includes nine meta property, which represent the common features of attributes. The attribute description specifies its meaning, data type, range of values, and so on as much as possible.

The physical domain attribute represents a subset of features that can be observed, queried, recorded, and measured in the physical space and geospatial of each resource feature constituting the cyberspace. Each attribute value is closely related to the objective existence of the corresponding resource feature in the physical world. Resources are at a higher level, the material basis of services.
