25 Security classification schema

25.1 General

The subject of the security_classification_schema is the definition of degrees of secrecy to be specified. This clause defines the information requirements to which implementations shall conform using the EXPRESS language as defined in ISO 10303-11. The following EXPRESS declaration begins the security_classification_schema and identifies the necessary external references.

Each implementation of an AP that uses this schema and that encodes entity names shall use the encoding specified in Annex A. Each reference to this schema in an open system shall use the identifier encoding specified in Annex B. This schema is illustrated in Annex D using the EXPRESS-G notation.

EXPRESS specification:

*)
SCHEMA security_classification_schema;

REFERENCE FROM support_resource_schema    --  ISO 10303-41
  (label,
   text);
(*

NOTE 1   The schemas referenced above are specified in the following parts:

support_resource_schema ISO 10303-41

NOTE 2   See Annex D for a graphical representation of this schema.

25.2 Fundamental concepts and assumptions

A security classification is the level of confidentiality that is required for the purpose of product data protection. Security classifications are assigned by some authoritative agency. Security classification information can be attached to any aspect of product data.

25.3 security_classification_schema entity definitions

25.3.1 security_classification   EXPRESS-G

A security_classification is the level of confidentiality that is required for the purpose of product data protection.

NOTE    The role of can be defined in the annotated EXPRESS schemas that use or specialize this entity, or by default, in an agreement of common understanding between the partners sharing this information.

EXPRESS specification:

*)
ENTITY security_classification;
  name : label;
  purpose : text;
  security_level : security_classification_level;
END_ENTITY;
(*

Attribute definitions:

name: the label by which the security_classification is known.

EXAMPLE    'National Security' is a security classification role. A security classification assignment role assigns the security classification role to a security_classification_assignment.

purpose: an informal description of the intent of the security_classification.

security_level: the security_classification_level that specifies the required degree of security.

25.3.2 security_classification_level   EXPRESS-G

A security_classification_level is a category of security required for product data protection.

EXAMPLE    'Confidential', 'secret', and 'top secret' are examples of security_classification levels.

EXPRESS specification:

*)
ENTITY security_classification_level;
  name : label;
END_ENTITY;
(*

Attribute definitions:

name: the label by which the security_classification_level is known.

NOTE    The meaning of this attribute can be defined in the annotated EXPRESS schemas that use or specialize this entity, or in an agreement of common understanding between the partners sharing this information.
