Terrorists and others may pose a cyber-threat to high-risk chemical facilities. Control systems, for example, could be manipulated to release hazardous chemicals. The Department of Homeland Security started a program more than a decade ago to help address these security risks.

We reviewed the program. DHS guidance designed to help about 3,300 facilities comply with cybersecurity and other standards has not been updated in over 10 years. Also, its cybersecurity training program for its inspectors does not follow some key training practices.

We made 6 recommendations, including that DHS review and update guidance and improve training.

What GAO Found

The Chemical Facility Anti-Terrorism Standards (CFATS) program within the Department of Homeland Security (DHS) evaluates high-risk chemical facilities’ cybersecurity efforts via inspections that include reviewing policies and procedures, interviewing relevant officials, and verifying facilities’ implementation of agreed-upon security measures. GAO found that the CFATS program has guidance designed to help the estimated 3,300 CFATS-covered facilities comply with cybersecurity and other standards, but the guidance has not been updated in more than 10 years, in contrast with internal control standards which recommend periodic review. CFATS officials stated that the program does not have a process to routinely review its cybersecurity guidance to ensure that it is up to date with current threats and technological advances. Without such a process, facilities could be more vulnerable to cyber-related threats.

Potential Cyber-Related Threats to Chemical Facilities

The CFATS program developed and provided cybersecurity training for its inspectors, but GAO found that the CFATS program does not fully address 3 of 4 key training practices, or address cybersecurity needs in its workforce planning process, as recommended by DHS guidance. Specifically:

  • The CFATS program does not: (1) systematically collect or track data related to inspectors’ cybersecurity training or knowledge, skills, and abilities; (2) develop measures to assess how training is contributing to cybersecurity-related program results; or (3) have a process to evaluate the effectiveness of its cybersecurity training in improving inspector skillsets.
  • The program also has yet to incorporate identified cybersecurity knowledge, skills, and abilities for inspectors in its current workforce planning processes or track data related to covered facilities’ reliance on information systems when assessing its workforce needs.

Fully addressing key training practices will help ensure that CFATS inspectors have the knowledge, skills, and abilities for cybersecurity inspections, and identifying cybersecurity needs in workforce planning will help the program ensure that it has the appropriate number of staff to carry out the program’s cybersecurity-related efforts.

Why GAO Did This Study

Thousands of high-risk chemical facilities may be subject to the risk posed by cyber threat adversaries—terrorists, criminals, or nations. These adversaries could potentially manipulate facilities’ information and control systems to release or steal hazardous chemicals and inflict mass causalities to surrounding populations (see figure). In accordance with the DHS Appropriations Act, 2007, DHS established the CFATS program to, among other things, identify and assess the security risk posed to chemical facilities.

GAO was asked to examine the cybersecurity efforts of the CFATS program, including the extent to which the program (1) assesses the cybersecurity efforts of covered facilities, and (2) determines the specialty training and level of staff needed to assess cybersecurity at covered facilities.

GAO conducted site visits to observe the cybersecurity portion of CFATS inspections based on scheduled inspections, reviewed inspection documents, and interviewed CFATS inspectors. GAO also analyzed inspection guidance and training against key practices and assessed workforce planning documents and processes.

What GAO Recommends

GAO is making six recommendations to DHS to routinely review guidance and update, as needed; to fully incorporate key training practices; and to identify workforce cybersecurity needs. DHS concurred with the recommendations.
