**Agriculture and Food**
The Agriculture and Food sector comprises systems of individual assets that are closely dependent upon each other. Because of its complexity, the sector has struggled to identify its most critical assets, systems, networks, and functions. Although the sector understands its individual systems and basic interrelationships, the challenge has been to understand the complexities and interdependencies across the farm-to-table continuum on national and regional scales. The Agriculture and Food sector has extensive, open, widely dispersed, diverse, and complex interdependent systems; therefore, the physical asset-based approach may not fit the Agriculture and Food sector.

**Banking and Finance**
The Banking and Finance sector may be divided into several functions: deposit and payments systems; credit and liquidity products; investment products; and risk transfer products. Various members of the Financial and Banking Information Infrastructure Committee (FBIIC) regulate each of these functions. The financial regulators, through their oversight authority, obtain a vast amount of information on institutions, critical assets and processes, and potential vulnerabilities. Sector-wide risks assessments are process-driven and address interdependence. Individual institutions also conduct their own risk assessments to identify and mitigate internal vulnerabilities and external dependencies. The Treasury Department, through collaboration and insights obtained from the members of the FBIIC, gathers sector-specific information. Although the definition of asset data is limited to the categories collected by the regulators, regulatory examinations and trade association surveys are thorough and provide adequate information for defining financial assets. General information for assets may include the following (as appropriate): • Asset name, mailing address, physical location,owner and (or) operator name; • Function or type of transaction – deposit and payments systems; credit and liquidity products, including investment and risk transfer; • Geographic region and financial center; • Number of employees; • Economic contribution – total market value of financial transactions conducted by or through the asset on a daily, weekly, monthly, and yearly basis; • International considerations; • Existing and planned protective measures; • Membership in a regional partnership or Information Sharing and Analysis Center (ISAC); • Dependence on other sectors – Communications, Energy, Information Technology, and Transportation; • Interaction with other assets (that is, other critical national assets directly and indirectly affected by the operation of each asset); • Backup capability – location and function of backup facilities (data center and business resumption); and • Substitutability – whether other industry systems or infrastructures would be able to serve the same function. Intangible assets, such as systems, databases, or networks, are linked to physical assets and locations. Systemically significant assets are stratified by their examination agency with respect to criticality to the financial services sector as a whole.

**Communications**
The complexity of sector assets, indepth corporate security programs, technology, and the numerous systems that make up the communications infrastructure help reduce the likelihood of a significant national-level network failure. For example, resiliency is achieved through the technology and redundancy employed in designing networks, and by encouraging customers to employ diverse primary and backup communications capabilities. Communications network architects employ technology and protocols (for example, Synchronous Optical Network (SONET) rings, and routing protocols), creating effective “self-healing” networks, and helping to mitigate risk at the design stage. Sector owners and operators focus on ensuring overall network reliability, maintaining “always on” capabilities for customers, and quickly restoring capabilities following a disruption. Data parameters for the sector will be defined primarily by the architecture elements of assets, systems, networks, and functions. Architectural elements in the Communications sector include the following: • Assets – shared assets and systems owned and operated by multiple companies Includes facilities in which equipment is collocated and systems shared by network operators, and equipment is owned and operated by the end user or located at the end user’s facility. Customers include individuals, organizations, businesses, and government. • Systems – signaling and control systems that exchange information about establishing a connection and control the management of the network; these systems access, primarily, the local portion of the network t end users to the backbone that enables users to send or receive communications. Access includes equipment and systems, such as Public Switched Telephone Network (PSTN) switches, Asynchronous Transfer Mode (ATM) switches, video servers for video on demand, and Internet Protocol (IP) routers for Internet service providers (ISPs). • Networks – core network/Internet backbone elements of the communications network that represent high-capacity network elements that servicing service regional, national, and international connectivity. • Functions – as defined in the National Infrastructure Protection Plan (NIPP), service, process, capability, or operations performed by specific infrastructure assets, systems, or networks.

**Defense Industrial Base (DIB)**
The DIB is a large, diverse, complex, interdependent, hierarchical, and free-flowing collection of asset owners and operators governed by various regulations, laws, treaties, and precedents. The U.S. Department of Defense (DoD) and the U.S. Census Bureau estimate that the DIB is composed of hundreds of thousands of worldwide Government and private sector sites, with capabilities to perform research and development, design, production, delivery, and maintenance of military weapon systems, subsystems, components, and parts to meet military requirements. Unlike other infrastructure sectors, the DIB is defined not based primarily on the type of goods and services it produces, but rather on who the customer is for these goods and services. It includes companies that perform under direct contract with the DoD, the subcontractors of these companies, and companies that provide incidental materials and services to either the DoD or the contractors. The DoD collects the following information on potential critical DIB assets: Contractor and Government entity code, name, street address, city, State, subject matter experts, facility security officers, and facility security officer contact information; Sales, employment, capacity utilization, square footage; Products, functions, production rates; Programs, components, and subsystems; Prime contractors, subcontractors, and critical subcontractors (first and second tier, selection criteria, products, and services); Business overview (for example, privately or publicly held, non-U.S. owned); Financial information; and Critical technologies. Once an asset is determined to be critical, the DOD collects the following additional information: Longitude and latitude; Buildings or other structures where industry manufactures or stores critical items; Dependencies (that is, the services and support that an asset requires to function) that a sectors asset has on other assets in the same sector and dependencies between assets from different sectors; Continuity and redundancy, including backups built into the asset (alternative sources of supply and backup production facilities); Impact on sector in cases of loss or failure (for example, economic, public health and welfare, public psyche, national security); Existing protective actions (for example, fencing, biometrics, firewalls); and Exposure to known foreign intelligence threat, such as treaty compliance regimes.

**Drinking Water and Waste Treatment Systems**
Drinking water and wastewater assets are defined as entire utilities for purposes of identification, prioritization, and coordination in the water sector. The water sector is composed of a diverse set of drinking water and wastewater utilities. Characteristics of these utilities useful for defining sector infrastructure information are available in databases maintained by the U.S. Environmental Protection Agency (EPA). Owners and operators are responsible for conducting risk assessments of their utilities to identify components (for example, pumps, generators, and supervisory control and data acquisition systems) the loss or damage of which, whether owing to manmade or natural events, could adversely affect the utility’s operation, threaten public health or the environment, or have significant economic impacts. Critical water sector infrastructure is owned and operated predominantly by the public sector (that is, local governments). The EPA, the U.S. Department of Homeland Security (DHS), and water sector owners and operators and security partners work together to develop robust threat, vulnerability, and consequence information to help water sector utilities identify their most critical components.

**Earth cover**
The Earth cover theme uses a hierarchical classification system based on observable form and structure, as opposed to function or use. This system transitions from generalized to more specific and detailed class divisions and provides a framework within which multiple land cover and land use classification systems can be cross-referenced. This system is applicable everywhere on the surface of Earth. This theme differs from the Vegetation and Wetlands themes, which provide additional detail.

**Emergency Services**
The Emergency Services System (ESS) consists of assets, systems, and networks that perform preparedness, prevention, response, and recovery functions so critical to protecting communities, saving lives, protecting property, and recovering essential community services in the wake of a disaster, that their incapacitation or destruction would have a debilitating impact on the Nation’s security, public health and safety, and psychological or moral well-being. Once nationally critical infrastructure and key resources (CI/KR) have been identified, assessed, and protected, the ESS will also address those CI/KR that are important at State, regional, tribal, and local levels. ESS assets, systems, networks, and functions embody physical, cyber, and human aspects or elements, as detailed below: • Physical CI/KR elements - An ESS facility may require specialized protection due to its unique or specialized characteristics. These can include anything that—if lost, stolen, released, damaged, compromised, or exploited—could cause an adverse effect or would be difficult to replace. Examples include: – Equipment. Unique devices, parts, or pieces of equipment; these include the key elements of communications systems; – Conveyances. Aircraft, vessels, or ground transportation vehicles housed within an ESS facility and used to carry out critical functions; – Materials. Critical items used in providing emergency service functions; and – Records. Documents in electronic or nonelectronic media. • Cyber CI/KR elements. These include cyber assets (for example, hardware and software components), systems (for example, a set of cyber assets that interact to perform a particular function), and networks (for example, interconnected assets and systems that store, process, or communicate information), as well as the information contained in them. Cyber CI/KR elements may be identified individually or included as a cyber element of a facility or asset, system, or network, and typically fulfill one of the following three roles: – Access control. Allowing only authorized personnel and visitors physical access to defined areas of a facility; – Control. Used to monitor and control sensitive processes and physical functions. Most communications systems fall within this role; – Warning and alert. Used for alerting and notification purposes to pass critical information that triggers protection and response actions. • Human elements or positions. These include positions staffed within ESS facilities that represent unique knowledge, skills, authorities, or roles, the absence of which could cause undesirable consequences. In general, the human aspect is best captured within the system or functional dimension of the assets, systems, networks, and functions continuum. They both serve as part of a system and help to perform or carry out critical functions. Categories of positions that support continuity of operations at all levels of government and functioning of the ESS include the following: – Strategic positions. Held by individuals and must be identified, assessed, and prioritized for protection to ensure continuity of essential government operations; and – Operational positions. Responsible for operating CI/KR systems, whose impairment could result in either cessation or takeover of operations, or whose compromise would make recovery from an attack more difficult (for example, law enforcement officials, HAZMAT experts, bomb squad members).

**Energy (except Nuclear Power)**
Broadly speaking, Homeland Security Presidential Directive 7 (HSPD–7) defines the energy sector as the Nation’s electric system (excluding nuclear powerplants and hydroelectric dams), natural gas system, and petroleum and petroleum product systems. These energy systems are highly interdependent (for example, natural gas is a significant fuel for electric generation) and are critical for other infrastructure sectors, including Communications, Drinking Water and Water Treatment Systems, Chemical, Information Technology, and Transportation Systems. Each of these interdependent energy systems consists of many individual assets, which in some cases may be highly important, but their importance varies dramatically depending on such factors as the time of day, the time of year, and system conditions. From a reliability and security perspective, however, systems are the critical characteristic of the energy sector. The Energy sector has identified six general asset or system characteristics that are important for evaluating the vulnerabilities of Energy sector infrastructure and for developing risk management programs: • Physical and location attributes – assist the Energy sector to develop consequence, vulnerability, and protective strategies; • Cyber attributes - help monitor and control the energy systems; • Volumetric or throughput attributes – define the extent of the damage, depending on the utilized capacity of the system, or points where the system may be capacity constrained; • Temporal/Load profile attributes – temporal or time-dependent dimension affected by the season of the year or the time of day; • Human attributes - include highly trained and skilled personnel who are key factors in a comprehensive Energy sector security plan; and • Importance of asset or system to the energy network – factors that impact the ability of power generation assets to function properly.

The Orthoimagery sub-channel, which is the only sub-channel currently populated, contains general information about rectified imagery, its sources, orthoimagery acquisition programs, and the access and dissemination of those data, including aerial photography, which is the source of orthoimagery. The Base Maps sub-channel category will consist of those base themes not covered by other categories. They are represented by such national datasets as the Geographic Names database and the National Land Cover Database. The Other Imagery sub-channel will consist of general information about imagery other than orthoimagery. Much of the information and data contained in this sub-channel will be satellite and other remotely sensed imagery.

**Information Technology**
Critical Information Technology sector functions support the sector’s ability to produce and provide high-assurance information technolgoy (IT) products and services for a variety of sectors. Through the IT sector-specific plan (SSP) development process, the sector identified six critical functions: • Provide IT products and services; • Provide incident management capabilities; • Provide domain name resolution services; • provide identity management and associated trust support services; • Provide Internet-based content, information, and communications services; and • Provide Internet routing, access, and connection services. These functions are distributed across a broad network of infrastructure, are managed on a proactive basis, and are therefore able to withstand and rapidly recover from most threats. These critical Information Technoogy sector functions are provided by a combination of entities—often owners and operators and their respective associations—who provide hardware, software, IT systems, and services. IT services include development, integration, operations, communications, and security. Information Technology sector entities include the following: • Domain Name System (DNS) root and generic top-level domain operators; • Internet service providers (ISPs); • Internet backbone providers; • Internet portal and e-mail providers; • Networking hardware companies (for example, fiberoptics makers and line acceleration hardware manufacturers) and other hardware manufacturers [for example, personal computer (PC) and server manufacturers and information storage companies); • Software companies; • Security services vendors; • Communications companies that characterize themselves as having an IT role; • Edge and core service providers; • IT system integrators; and • IT security associations. In addition, Federal, State, and local governments are a component of the Information Technology sector as providers of government IT services that are designed to meet the needs of citizens, businesses, and employees. The Information Technology sector includes public and private sector entities.

**Manufacturing Facilities**
Today’s manufacturing environment has several underlying characteristics that influence its business risks, security posture, and continuity of operations. These characteristics include the following: 1. Most manufacturing enterprises are integrated into complex, interdependent supply chains. A failure in any part of the supply chain can ripple through manufacturing systems, causing cascading economic impacts; 2. Supply chains have been optimized for productivity and efficiency—such methods as just-in-time production have created some fragile supply networks that are susceptible to disruptions; 3. Manufacturers rely highly on information and communications systems; this reliance has introduced new cyber risks that could degrade, damage, or shut down operations; 4. Globalization and outsourcing has caused some U.S. manufacturers to become highly reliant on foreign sources of supply and the transcontinental transportation systems that support them; 5. Manufacturers rely heavily on electricity and fuels, sometimes with only limited power backup and fuel storage. These characteristics increase the likelihood that a disruption in an existing critical infrastructure and key resources (CI/KR) sector could have major economic consequences on the manufacturing industries. Conversely, a direct attack on or disruption of certain elements of the manufacturing industries could disrupt essential functions in some CI/KR sectors.

**National Monuments and Icons (NMI)**
A number of NMI assets located within the United States and its Territories (for example, Puerto Rico and the Northern Mariana Islands) are listed on the National Register of Historic Places or the List of National Historic Landmarks. The National Register of Historic Places is the Nation’s official list of cultural resources reserved for preservation. The National Historic Landmarks are significant historic places designated by the Secretary of the Interior for their exceptional value or quality in illustrating or interpreting the heritage of the United States. Currently, fewer than 2,500 historic places bear this national distinction. The criteria applied to evaluate properties for possible designation as National Historic Landmarks are delineated in the Code of Federal Regulations (36 CFR 65.4, National Historic Landmark Criteria). Through the U.S. Department of Homeland Security (DHS) and State Offices of Homeland Security, the U.S. Department of the Interior (DOI) will work at the Federal, State, tribal, and local government levels, and with the private sector, to identify other NMI assets that may not be on either list but should be considered as National Critical.

**Themes**
Representations of conceptual topics describing digital spatial information for the Nation. Themes contain associated datasets (with attribute records and coordinates) that are documented, verifiable, and officially designated to meet recognized standards. A theme contains one or more datasets of geographic information to be used in common and from which other datasets can be derived. Themes are listed in OMB Circular A–16.

*Date:* November, 2010

**Topics**
The central concept for applying context to data; an aggregate of characteristics, occurrences, and roles played in associations with other topics, whose organizing principle is a single subject. A subject (an area of study) is, in the most generic sense, anything whatsoever, regardless of whether it exists or has any other specific characteristics, about which anything whatsoever may be asserted by any means whatsoever.

**Transportation**
Transportation data are used to model the geographic locations, interconnectedness, and characteristics of the transportation system within the United States. The transportation system includes both physical and nonphysical components representing all modes of travel that allow the movement of goods and people between locations.

**Transportation (marine)**
The Navigation Channel Framework consists of highly accurate dimensions (geographic coordinates for channel sides, centerlines, wideners, turning basins, and river mile markers) for every Federal navigation channel maintained by U.S. Army Corps of Engineers (USACE). The Navigation Framework will provide the basis for the marine transportation theme of the geospatial data framework.

**Transportation networks**
Transportation data are used to model the geographic locations, interconnectedness, and characteristics of the transportation system within the United States. The transportation system includes both physical and nonphysical components representing all modes of travel that allow the movement of goods and people between locations. Typical keywords are roads, airports/airstrips, shipping routes, tunnels, nautical charts, vehicle or vessel location, aeronautical charts, or railways.

**Transportation Systems**
The national transportation network is a large, multifaceted, interdependent mix of links, nodes, flows, processes, agreements, rules, relationships, and regulations. This complex cloud of activity must be reduced into more manageable data to be used for risk analysis. To assist stakeholders within the Transportation Systems sector in defining systems, thematic perspectives or risk views will be used. It presumed that data collected in these views will be collectively exhaustive. Instead, the risk view structure supports a scalable system analysis capability, allowing for the examination of how risk manifests in the system. Risk views are the first step in defining the boundaries of a system, establishing relationships within the system, and identifying interdependencies. The initial set of risk views includes the following: • Modal – Traditional industry delineation (that is, aviation, maritime, mass transit, highway, freight rail, and pipeline). All assets within a mode can be collectively evaluated as a system. • Geographic – All assets within a geographic boundary (for example, New York State or the city of Los Angeles). This view may be used most often by the grants and training (G&T) community, and State, tribal, and local government partners. • Functional – All assets that, taken together, perform a specific function or service (for example, supplying fuel to the Northeast). This view is supply chain-focused and may be used by, for example, the U.S. Coast Guard (USCG), U.S. Customs and Border Protection (CBP), interagency hazardouse materials (HAZMAT) transportation working groups, and private sector partners. • Ownership – All assets that fall under a defined set of decision rights, recognized by Federal, State, tribal, and local governments (for example, all assets owned and operated by the New York Mass Transit Authority) can be evaluated as a system.
