The Port Resiliency for Operational/Tactical Enforcement to Combat Terrorism Model

PROTECT: A partnership of the U.S. Coast Guard and academia

To address the need for randomization and resource optimization a Literature Review was conducted by the LantArea Operations Analysis (LANT-7) division. One of the first projects discovered that offered a possible framework for this requirement had been developed by the University of Southern California’s (USC) Department of Homeland Security (DHS) Center of Excellence (CoE) – the National Center for Risk and Economic Analysis of Terrorism Events (CREATE). The DHS Science and Technology’s Office of University Programs CoE Program matches world-class researchers with DHS component operators to “perform research and development activities to provide critical homeland security tools, technologies, training, and talent [including more than 40 tools, technologies, and knowledge products either in pilot studies or use the Office of University Programs: Product Overviews].”

CREATE had addressed the need for randomization and resource optimization in their application of game theory at the International Airport in Los Angles (LAX). They worked with local law enforcement to develop a computer-based model that looked at the checkpoint and canine patrolling/monitoring problem at the airport as a Bayesian Stackelberg game (a method of combining a means for calculating probability that incorporates learning with a defender-attacker sequence game theory). With this model, the CREATE team developed the Assistant for Randomized Monitoring Over Routes (ARMOR) Program. ARMOR appropriately weighs the different actions in randomization taking into account different target weights, as well as the fact that the adversary will conduct surveillance, and that there is uncertainty over adversary types.

ARMOR has been successfully deployed since August 2007 at LAX to randomize checkpoints on the roadways entering the airport and canine patrol routes within the airport terminals. ARMOR was also successfully deployed by the Federal Air Marshal Service to randomize the deployment of resources on international flights.

Based on the success of ARMOR, LantArea joined with their PacArea counterparts and the service’s Research and Development Center (RDC) to take the program and adapt it to a maritime environment application. This RDC team developed the PROTECT Model. The development of the PROTECT Model was made possible through a flawless partnership between the Coast Guard’s operational- and tactical-level commands and academia.

The LantArea, PacArea, and RDC team looked at every port in the United States as a candidate to determine which would serve as a test bed for PROTECT. They collectively settled on the Boston, Mass., port. It was chosen for its relatively simple and constrained geographic properties and mix of critical infrastructure. With a port chosen, the USC research team developed and applied randomizing security strategies (patrols, checkpoints, inspections, etc.) based on rigorous game-theoretic modeling and solution algorithms.

The project goal was to use USC CREATE’s modeling prowess to maximize the effectiveness of Coast Guard resources in conducting its ports, waterways, and coastal security mission. This project also presented the USC academic team a new problem with real-world ramifications that would provide the research team several areas of exploration. At the same time that PROTECT’s team was embarking on algorithm development, a second DHS CoE – Purdue University’s VACCINE Center (Visual Analytics for Command, Control, and Interoperability Environments) – developed the data visualization to support the model. David Ebert, Ph.D., director of VACCINE, noted, “In PROTECT Phase I, the value of our team’s visualization and temporal analytics became clear. The initial integrated analysis and visualization clearly identified patterns in the historical data. Moreover, the visualization and analysis identified patterns and issues during the development of the PROTECT Model that enabled the model to be quickly refined to alleviate these patterns and allow USCG personnel to consider their assigned RIN [risk] values and their affect on the scheduling of PWCS patrols.”

A Boston “game board” was developed for the port with different geographic components. Based on critical infrastructure groupings and the physical layout of the port, nine patrol areas (PAs) were identified. The PROTECT Model generated a 60-day optimized random PWCS critical infrastructure pilot-test patrol schedule providing Coast Guard Sector/Station Boston patrol coordinators the time of day to start the patrol, PAs to visit, the sequence of visit, and what activity to perform (query, observe, or transit) at each PA.

A consideration for any new scheduling function is the ease with which the organization is able to incorporate the functions into their daily operational execution plan. A key collateral gain of the 60-day patrol forecast is the planning for asset availability. Coast Guard Station Boston leadership and boatcrews reported that the schedule was easily implemented and improved their ability to plan and schedule crew rest intervals, required training evolutions, and scheduled boat maintenance. Success was measured not only by the elimination of patrol patterns previously identified, but in addition, by exceeding all service visit count requirements without increasing the number of boat hours or crews, and higher revisit rates on critical infrastructure that presented the greatest risk as measured by the Coast Guard’s Maritime Security Risk Assessment Model.

In February 2012, PROTECT’s research focus shifted from Boston to New York City, a more complex area of operations. As more complex defender-attacker strategies and other PWCS activities are modeled, tested, and determined to be valid for each sector, the RDC plans to integrate them into the overall PROTECT Model. The output will be a Microsoft® Excel spreadsheet schedule sent to the patrol planning (response) branch in that sector. The USC team continues to refine the model, adding additional complexity and rigor while considering evaluating changes to procedures and tactics to the output of the model.

Rear Adm. Daniel Neptun, commander, 1st Coast Guard District, which includes the ports of Boston and New York, noted: “The partnership across the DHS Centers of Excellence, and with the Coast Guard, added synergy and excitement into an important, but otherwise routine process – conducting harbor patrols to improve maritime domain awareness and enhance harbor safety and security. The result was invigorated boatcrews more focused upon providing effective presence, reducing predictability, and enhancing the safety and security within our ports. PROTECT-guided patrols became a source of pride for my boatcrews, and it doesn’t get much better than that! The results have been exceptional, and we continue to refine the product for what I hope will be the eventual servicewide use. I am optimistic that this will be the first of many mutually beneficial projects in the years ahead.”

Vice Adm. Robert C. Parker, commander, LantArea, explained the value of the project when he noted: “The example of the collaboration on the PROTECT Model is a wonderful partnership of academia and the Coast Guard because it empowers us to be more random, and less predictable in our ports, waterways, and coastal security mission. Our maritime safety and security presence enables American prosperity and synergies, and partnerships like PROTECT help make America safer.”

PROTECT has provided the Coast Guard with the means to both fully randomize and optimize its tactics, techniques, and procedures for conducting critical infrastructure patrols. As noted at the beginning of this article, randomization is critical to minimizing a terrorist’s ability to circumvent the service’s security operations. This was made possible through an effective partnership of operators and academics. This partnership underscores what the Coast Guard and academia can do … this is just the beginning.
