(ONG) pipeline industry, which includes, but is not limited to, natural gas
and hazardous liquid transmission pipeline systems, natural gas distribution
pipeline systems, liquefied natural gas (LNG) facilities, propane air facilities,
and others involved in these industries. This standard was developed to
provide an actionable approach to protect IAC essential functions by
managing cybersecurity risk to IAC environments. IAC environments can
include, but are not limited to, supervisory control and data acquisition

Facility Security Plan Methodology for the Oil and Natural Gas
Industries
Provides the framework to establish a secure workplace. The plan provides
an overview of the threats facing the facility and describes the security
measures and procedures designed to mitigate risk and protect people,
assets, operations, and company reputation. This API standard was
prepared with guidance and direction from the API Security Committee, to
assist the petroleum and petrochemical industries in the preparation of a
Facility Security Plan (FSP). This standard specifies the requirements for
preparing an FSP as well as a discussion of the typical elements included in
an FSP.
This standard is intended to be flexible and adaptable to the needs of the
user. It is noted that the content of an FSP can vary depending on
circumstances such as facility size, location, and operations. This
methodology is one approach for preparing an FSP at petroleum and
petrochemical facilities. There are other security plan formats available for
the industry. It is the responsibility of the user to choose the format and
content of the FSP that best meets the needs of a specific facility. The format
and content of some FSPs should be dictated by government regulations for
covered facilities. This standard is not intended to supersede the
requirements of any regulated facility but may be used as a reference
document. Pages: 82
