More About the Office of Infrastructure Protection

The Office of Infrastructure Protection (IP) leads the coordinated national program to reduce and mitigate risk to the nation’s critical infrastructure from acts of terrorism and natural disasters and to strengthen the ability of critical infrastructure owners and operators and other stakeholders to respond to and quickly recover from an emergency.  

Office of Infrastructure Protection Divisions

IP is divided into five divisions and the National Infrastructure Coordinating Center:

Infrastructure Analysis and Strategy Division IASD provides strategic, operational, and tactical products and services to the Department and its partners through an analytic framework that integrates:

• Critical infrastructure and risk analysis across physical – cyber domains;

• Strategic, operational, and tactical risk analysis;

• Risk methodology development, modeling, and capabilities development; and

• Intelligence analysis and operations.

IASD maintains the Homeland Security Infrastructure Threat and Risk Analysis Center (HITRAC), an internal Department coordination center, and the National Infrastructure Simulation and Analysis Center (NISAC).

 Infrastructure Information Collection Division IICD leads the Department’s efforts to protect and provide standardized, relevant, and customer-focused infrastructure data to homeland security partners.

Infrastructure Security Compliance Division ISCD leads the Department’s efforts to secure America’s high-risk chemical facilities and prevent the misappropriation of certain chemicals for use in terrorist acts on the homeland through the systematic regulation, inspection, and enforcement of Chemical Facility Anti-Terrorism Standards.

National Infrastructure Coordinating Center The NICC is the information and coordination hub of a national network dedicated to protecting the critical infrastructure of the United States by providing 24/7 integrated critical infrastructure support to DHS and critical infrastructure partners in order to reduce risk, prevent damage, and enable rapid recovery of critical infrastructure assets from incidents caused by all hazards.

Protective Security Coordination Division PSCD provides strategic coordination and field operations support to reduce risk to the nation’s critical infrastructure from a terrorist attack or natural disaster through site vulnerability assessments, Protective Security Advisors, the Regional Resiliency Assessment Program, and the Office for Bombing Prevention.

Sector Outreach and Programs Division SOPD executes the national effort to build, sustain, align, and leverage public-private partnerships  with critical infrastructure stakeholders. Through strong collaboration with its partners, SOPD works across IP to develop and implement risk-informed programs that improve mitigation capabilities across the nation, thus enhancing critical infrastructure protection and resilience. SOPD is also the Sector-Specific Agency for six critical infrastructure sectors:
