The Cybersecurity and Infrastructure Security Agency (CISA) has announced plans to overhaul its Automated Indicator Sharing (AIS) system, a crucial tool designed to share cybersecurity threat information, following a government watchdog report that revealed several shortcomings within the program. The Department of Homeland Security’s Office of the Inspector General (OIG) released a report last Friday highlighting concerns about declining participation, lack of outreach efforts, and missing information on program expenditures.
The AIS System: An Essential Cybersecurity Tool
Automated Indicator Sharing (AIS), created in 2016 as part of the Cybersecurity Act of 2015, was designed to facilitate the real-time exchange of cyber threat intelligence between federal entities and public-private sector partners. The system shares machine-readable threat intelligence such as vulnerabilities and hacking tactics, enabling quicker response times to emerging cyber threats. It was seen as a critical element in protecting the nation’s cybersecurity infrastructure.
However, the OIG report revealed significant issues that have hampered the program’s effectiveness. The most alarming finding was the steep decline in participation, with the number of AIS users dropping from 304 participants in 2020 to just 135 in 2022. The sharing of cyber threat indicators also plummeted by 93% over the same period, a troubling trend considering the system’s importance in fostering collaborative defense against cyberattacks.
Why Did AIS Participation Decline?
The OIG attributed much of the decline to a lack of outreach from CISA. “CISA paused outreach efforts for promoting AIS in May 2022, which led to a significant reduction in participation,” the report noted. One major stakeholder, according to the report, only discovered the existence of the AIS system by conducting its own research and directly contacting CISA.
Another contributing factor was the decision by an unspecified federal agency to stop sharing threat intelligence with AIS, citing “security concerns with transferring information from its current system.” This loss significantly impacted the volume of cyber threat indicators being shared through AIS.
Compounding these challenges, CISA could not provide detailed expenditure data related to the AIS program, limiting the OIG’s ability to assess whether taxpayer funds had been used effectively. The agency reported spending $31 million in 2021 and $35 million in 2022 on information-sharing capabilities but did not offer a breakdown of how that funding was specifically allocated to AIS.
CISA’s Commitment to Address the Issues
Following the report, CISA has pledged to resolve the issues flagged by the inspector general. In a statement, CISA announced plans to revitalize AIS, with a focus on active recruitment and retention of participants, including federal data producers. The agency has also agreed to create detailed spending plans for the program, addressing the OIG’s concern about the lack of financial transparency.
“CISA is committed to strengthening the sharing of cyber threat information and improving documentation of future costs related to AIS,” a spokesperson said. The agency has already begun implementing the recommendations, including exploring alternative approaches to automated threat intelligence and information sharing.
What’s Next for AIS?
CISA’s Cybersecurity Division is currently leading an independent evaluation of the AIS service, with plans to present recommendations to leadership by July 2025. The agency aims to develop a spending plan by December 2024, which will offer better financial oversight of the program. This evaluation will help CISA align the AIS system with its new long-term Threat Intelligence Enterprise Services strategy.
While the agency’s response to the watchdog report was generally well-received, the OIG noted that CISA had not addressed the need for performance metrics to track the program’s success. This omission remains unresolved, though CISA has 90 days to provide further documentation to the inspector general.
A Broader Issue in Public-Private Cybersecurity Partnerships
The challenges faced by AIS are not unique to this program. In June, a key public-private cybersecurity partnership initiative under CISA faced backlash, with several participants voicing concerns about mismanagement and slow response times to shared intelligence. The criticism underlines the growing demand for better coordination between the public and private sectors in the fight against cyber threats.
As ransomware and other cyberattacks become increasingly sophisticated, the need for robust, real-time intelligence sharing systems like AIS cannot be overstated. The ability to quickly disseminate information about active threats and vulnerabilities is crucial for both federal entities and private organizations to mount an effective defense. Without an efficient and well-participated system, the nation’s critical infrastructure remains at greater risk of cyberattacks.
Looking Forward: Cybersecurity and Accountability
The recent watchdog report emphasizes the need for not only stronger cybersecurity measures but also greater accountability and transparency in how government programs are funded and managed. CISA’s willingness to implement the OIG’s recommendations is a positive step forward, but the full revitalization of AIS will depend on how quickly and effectively these changes are made.
The long-term success of AIS will require a clear outreach strategy to attract and retain participants, more robust tools to enhance the functionality of the platform, and transparent financial practices to ensure that taxpayer funds are used effectively. The cybersecurity landscape is evolving, and tools like AIS must evolve with it to ensure the protection of both public and private entities from cyber threats.
