C.2.6.2 Official Information Dissemination Information Type

Official Information Dissemination includes all efforts to provide official government
information to external stakeholders through the use of various types of media, such as video,
paper, web, etc. The recommended security categorization for the official information
dissemination information type is as follows:
Security Category = {(confidentiality, Low), (integrity, Low), (availability, Low)}
The confidentiality impact level is the effect of unauthorized disclosure of official information
dissemination information on the ability of responsible agencies to provide official Federal
government information to external stakeholders through the use of various communications
media. Official information dissemination information is usually in the public domain and poses
no confidentiality impact.
Recommended Confidentiality Impact Level: The provisional confidentiality impact level
recommended for official information dissemination information is low.
not on the time required to detect the modification or destruction of information. In general, the
adverse effects of unauthorized modification or destruction of official information dissemination
information on overall agency mission functions will be limited.
Special Factors Affecting Integrity Impact Determination: There is a potential for customer actions
taken based on modified or incomplete information. In addition, unauthorized modification or
destruction of official information dissemination information may result in distribution of false
and misleading information (e.g., modified web pages, electronic mail, video). Such events can
adversely affect operations or public confidence in the agency. This can significantly degrade
the official information dissemination mission capability. In such cases, a moderate integrity
impact may exist. Also, the more serious integrity impacts become increasingly likely as E-
government initiatives progress.
Recommended Integrity Impact Level: The provisional integrity impact level recommended for
official information dissemination information is low.
mission, not on the time required to re-establish access to the official information dissemination
information. Official information dissemination processes are generally tolerant of limited
delays. However, even temporary loss of availability of official information dissemination
information is likely to have an adverse effect on public confidence in the agency. In most cases,
disruption of access to official information dissemination information can be expected to have
only a limited adverse effect on overall agency operations, agency assets, or individuals.
Special Factors Affecting Availability Impact Determination: While most cases will result in only
limited consequences, repeated outages can have a serious adverse effect on public confidence in
the agency. This can significantly degrade the official information dissemination mission
capability. In such cases, the availability impact might be moderate.
Recommended Availability Impact Level: The provisional availability impact level recommended for
official information dissemination information is low.
