CRITICAL INFRASTRUCTURE Protecting Critical Infrastructure from Terrorism: A Risk-Based Multi-Hazard Approach to Vulnerability Assessment Reducing the Risks and Consequences of Terrorism CREATE Conference November 18, 2004 Professor Rae Zimmerman New York University/Wagner Graduate School of Public Service
Research ObjectivesElectric Power Case • Develop Critical Infrastructure as a Focus for and Demonstration of the Assessment of Risk, Consequences, Emergency Response and Economic Impact • Provide Inputs from Electric Power Case to Risk and Economic Modeling, including: • electric power system configuration • common mode failures • indicators for interdependencies with other infrastructure
Why Infrastructure? • Attention of Federal Policy: 1996-2004 • Public Concern; Contributes about 10% to Gross Domestic Product (Henry and Dumagan 2004) • Highly Interdependent Centralized Production Systems and Networked Distribution Systems • Large Consequences of an Attack: Extensive Number of Users Exposed • Proven Targets of Terrorism • Interconnections that Magnify Impacts
Attention of Federal Policy: CHRONOLOGY OF SELECTED FEDERAL INITIATIVES INCORPORATING INFRASTRUCTURE 1996 Executive Order 13010 1997 President’s Commission on Critical Infrastructure Protection 1997 U.S. Department of Commerce Critical Infrastructure Assurance Office 1998 Presidential Decision Directive (PDD) 63 2001 USA Patriot Act Section 1016 2002 National Strategy for Homeland Protection 2003 Homeland Security Presidential Directive (HSPD)7 and 8 2003 National Strategy for the Physical Protection of Critical Infrastructures 2004 National Incident Management System (NIMS)
Proven Targets of Terrorism or Sabotage: TRANSIT and WATER TRANSIT • 1900s: Hundreds of Subway Attacks Outside U.S.(Mineta Institute) • 1995: Tokyo Sarin Gas on 3 Separate Lines • 1995: Subway Car Bombings - St. Michel-Notre Dame Station • 1995: Derailment of Amtrak’s Sunset Limited (AZ) (vandalism) • 2001: Destruction of Lower Manhattan Subway Lines (WTC) • 2004: Madrid Subway Bombings WATER • 2003: break-ins at water systems in 5 states and Canada • Poisoning threats in Turkey, Germany and Malta Source: R. Zimmerman, “Water” in Digital Infrastructures, edited by R. Zimmerman and T. Horan (Routledge 2004).
Proven Targets of Terrorism or Sabotage: ELECTRIC POWER • Domestic attacks on power plants: “70 percent of energy and power companies experienced at least one severe cyber attack.” ( U.S. GAO 2004: 12) • Transmission Towers: Vandalism occurred in October 2004, when two bolts were removed from a transmission tower in Milwaukee, WI disrupting power and rail service when the tower fell on to the lines (USA Today 2004). • Crude oil and gas pipelines: Between June 2003-September 2004, in Iraq, over one hundred attacks on oil and gas pipelines were reported.
System Interconnectedness (Macro and Micro Effects) ENERGY TRANSPORTATIONWATER TELECOMMUNICATIONS
Macro Interdependencies: 2003 Total Energy Consumption by SectorSource:Drawn from U.S. Department of Energy, Energy Information Administration, Monthly Energy Review, October 2004
Micro Interdependencies: Energy use at the East Bay Municipal Utilities District OAKLAND, CA Energy Inputs Onsite Power Generator 2.6 MW Western Area Power Authority 4.16 MW Pacific Gas and Electric EBMUD Surplus Power Oxygenation Plant 27% Activated Sludge Mixing 22% Headworks 18% Lighting, Losses, Misc. 12% Solids Handling 10% Activated Sludge Pumping 7% Other Motor Loads 4% Energy Outputs Diagrammed from Hake, Bray and Kallal (2004)
Types of Potential Disruption and Vulnerability Associated with Interdependencies GENERAL EFFECTS • Single System Effects • Multiple System Effects (e.g., J. Peerenboom, R. Fisher, R. Whitfield): Common-Cause; Cascading; Escalating GENERIC ELECTRIC POWER CASE: Disruption by Terrorism • Multiple modes of attack possible • Numerous cascading effects • Many second and third level consequences • Enormous economic impacts of sustained regional electricity disruption
ILLUSTRATIVE EXAMPLE: U.S. and CanadianBlackout of August 14, 2003 • One set of initiating events: cyber failures • Series of cascading failures of electrical systems • Interdependencies: transportation, water, sanitation, communications failures • Economic and social impacts: health and recreation; job disruption; disruption and redistribution of economic sectors • Numerous analogies to consequences of a terrorist attack

Research Approach: Electric Power 1.Identify Event Case Databases (“all-hazards” approach): U.S. DOE, U.S. DHS, websites, etc. 2.Case Diagnosis of Failures: Identify and code- • characteristics of failures • Interdependencies with other infrastructure • vulnerable components and consequences 3.Develop and Apply Indicators of Infrastructure Interdependency 4.Identify Risk Reduction Options

Risk and Consequence Reduction Options for Electricity: Post 9/11 (WTC) Examples • Redundancy/Service Alternatives • Spare transformer vaults at the South Street Seaport provided energy to damaged areas • Use of Slack Resources • Ability to access portable generators provided temporary power • Decentralization and Decoupling • Alternative, portable energy sources used

Conclusions • Electric power is a key driver of other infrastructure and impacts other infrastructure in extreme events • Grid configurations, common component failures and their consequences guide risk estimates of terrorist attacks • Risk reduction alternatives exist that can alter vulnerability of energy service configurations to attack • Outputs of case-based diagnostic methods and indicators provide inputs to risk and economic models
