DHS partners with a broad range of stakeholders to provide resources to help organizations and facilities plan for an active shooter incident.

Access and Functional Needs

This Active Shooter Preparedness: Access & Functional Needs - What You Should Know video provides insightful information for critical infrastructure owners and operators to better understand the unique and complex challenges that persons with disabilities, and access and functional needs face during an active shooter incident.

Business Continuity Planning Suite

With the goal of helping a business or organization better prepare to minimize disruption of service and maintain normal business operations during an emergency or crisis, the Business Continuity Planning Suite aims to create, update, or improve an organization’s business continuity plan. The suite provides an overview on business continuity planning, prepares users to write their own plan, and has tools to generate a plan tailored to their specific organization.

Hospitals and Healthcare

Hospitals and healthcare facilities face a unique set of challenges in an active shooter incident. These incidents have no patterns in victim selection or method, creating an unpredictable and quickly evolving situation that can lead to loss of life and injury. Numerous factors associated with hospital and healthcare environments complicate traditional response to active shooter incidents, including the “duty-to-care”, also known as “duty-to-act”, commitment and the varying levels of patient mobility and patient special needs. Additionally, staff must consider response planning for patients that require the greatest allocation of resources, as well as the unique characteristics within the hospital and healthcare environment. Visit this Hospitals and Healthcare Facilities Action Guide for more information.

Public Demonstrations and Outdoor Eating Venues

The Protecting Infrastructure During Public Demonstrations document offers security recommendations for businesses that may be the target of unlawful acts during public demonstrations. The document provides options for consideration to mitigate risk and access to CISA resources to assist with decision-making.

The Protecting Patrons in Outdoor Eating Venues document identifies security measures for restaurants that choose to conduct business outside. Restrictions in operations from COVID-19 have forced restaurants to set up tables outside, creating a potential vulnerability of an attack.  This product identifies various potential threats such as vehicle ramming, including security measures restaurants and the municipality can enforce to help mitigate the threat, and actions to take if an attack occurs. 

Protecting Patrons During Holiday Shopping Season

The Protecting Patrons During the Holiday Shopping Season document helps mitigate the impacts of a potential attack. Given the increase of patrons in shopping venues during the holidays, individuals or groups intending to inflict harm or disrupt festivities may also leverage the corresponding shopping season as an opportunity to engage in grievance-based violence. Although there are currently no credible or imminent threats, shopping venues should assess existing security practices to ensure effective procedures are in place.

Personal Security Considerations

The CISA Personal Security Considerations fact sheet encourages critical infrastructure owners and their personnel to remain vigilant and report suspicious behavior that individuals may exhibit in order to thwart an attack. It also contains several easily implementable security measures that can mitigate threats to personal safety.

You can find the Personal Security Considerations fact sheet translated into Korean.

Physical Security Considerations for Temporary Facilities

The Physical Security Considerations for Temporary Facilities fact sheet helps temporary facilities— defined as those that are established for set time frames for hosting a venue— navigate the unique security challenges due to their provisional nature. The dynamic threat environment, inclusive of international and domestic violent extremists emphasizing attacks in public gathering locations, further underscore the importance of incorporating security measures to keep facilities and people safe.

The Physical Security Considerations for Temporary Facilities fact sheet informs operators how to determine if the facility has a security plan in place, if existing protective measures provide necessary security for the event, and how to conduct a vulnerability assessment to identify and prioritize areas of concern that need to be addressed. It also provides cost-effective protective measures to mitigate identified vulnerabilities and enhance security, and access to resources to support decision-making.
