Infrastructure Survey Tool

The Infrastructure Survey Tool (IST) is a voluntary, web-based security survey conducted by Protective Security Advisors (PSAs) in coordination with facility owners and operators after an Assist Visit to identify and document the overall security and resilience of the facility. The security survey is conducted to:

  • Identify facilities’ physical security, security forces, security management, information sharing, protective measures, and dependencies related to preparedness, mitigation, response, resilience, and recovery.
  • Identify security gaps.
  • Create facility protective and resilience measures indices that can be compared to similar facilities.
  • Track progress toward improving critical infrastructure security.

IST Results

The survey data, composed of weighted scores on a variety of factors for the specific facility, are provided to owners and operators through the IST Dashboard that compares the data against similar facilities and informs protective measures, resilience planning, and resource allocation. In addition to providing a security and resilience posture overview, the dashboards also highlight areas of potential concern and give owners and operators the ability to preview how specific enhancements to security and resilience measures will potentially improve the security and resilience of their facility.

This is an example of the information displayed in the IST Dashboard. At the top are six bar graphs displaying the example facility's scores for overall security, physical security, security management, security force, information sharing, and protective measures. Each bar graph is compared to other facilities so determine how it ranks compared to other similar facilities.

A written report, developed from the IST data, contains a description of the facility and its vulnerabilities as well as recommendations to mitigate identified vulnerabilities. The information is protected under the Protected Critical Infrastructure Information (PCII) Program and is used by DHS for steady-state analysis, special event planning, and incident management. PCII may also be shared with authorized representatives of homeland security stakeholder agencies at all levels of government who have a valid need to know the information.
