About the Infrastructure Information Collection Division

The National Protection and Programs Directorate/Office of Infrastructure Protection's Infrastructure Information Collection Division (IICD) leads the Department’s efforts to gather and manage vital information regarding the nation’s critical infrastructure. Accurate critical infrastructure data is essential to developing and executing infrastructure protection programs at all levels of government. IICD helps ensure that the necessary infrastructure data is available to homeland security partners by identifying information sources and developing applications to use and analyze the data.

IICD equips federal, state, and local governments with tools for the collection, management, and visualization of infrastructure data to support national preparedness, response, and recovery efforts.

Resources and Tools to Support Infrastructure Protection and Resilience

Critical Infrastructure Data Collection

To help homeland security personnel and emergency responders collect and manage information about critical infrastructure in their communities, IICD provides the Automated Critical Asset Management System (ACAMS) at no cost to state, local, tribal, and territorial governments. The comprehensive set of tools and resources in ACAMS support infrastructure protection programs by helping streamline collection efforts.

IICD, in collaboration with Homeland Infrastructure Threat and Risk Analysis Center (HITRAC), manages the National Critical Infrastructure Prioritization Program's (NCIPP) Data Call process.

The NCIPP Data Call is the primary method for the Department to collect, identify, and prioritize critical infrastructure information from states, the 18 critical infrastructure sectors, and other homeland security partners across the nation. The NCIIP Data Call uses an enhanced Infrastructure Data Collection Application, which provides the ability to input data throughout the year.

Critical Infrastructure Data Management and Protection

IICD establishes standards, requirements, and procedures to help ensure the consistency and relevance of data collected. As part of this effort, IICD developed and maintains the Infrastructure Data Taxonomy, a common terminology for communicating about critical infrastructure.

To enhance information-sharing efforts among the public and private sectors, the Protected Critical Infrastructure Information (PCII) program provides congressionally mandated protections from public disclosure to qualifying critical infrastructure information. The success of the nation’s collaborative critical infrastructure protection program relies on participation from critical infrastructure owners and operators and PCII provides those owners and operators assurance that their sensitive information can be protected.


IICD manages infrastructure information partnerships with homeland security geospatial stakeholders in state and local governments, as well as the private sector. These partnerships include activities such as working to define better geospatial information requirements and to improve data sharing, creating geospatial data sets for partner use, assigning staff to work in the field and serve as focal points for state and local data needs, and managing workshops to address future geospatial information issues in homeland security and emergency response.

IICD is in the process of replacing its current suite of Web-based visualization tools available through the Integrated Common Analytical Viewer (iCAV).
