Tennessee lawmakers have introduced Senate Bill 378, a significant piece of legislation aimed at bolstering the state’s defenses against cyber threats targeting critical infrastructure. Introduced on February 12, 2025, the bill seeks to enhance the security of essential services such as water supply, energy, and transportation systems, which are increasingly vulnerable to cyberattacks.

The primary purpose of Senate Bill 378 is to empower the state’s attorney general to intervene in cases where proposed sales, transfers, or investments in critical infrastructure could pose a threat to state security. If a court finds that such actions jeopardize public health or economic stability, it can issue a permanent injunction against them. This provision aims to safeguard Tennessee’s critical infrastructure from foreign and domestic threats, ensuring that essential services remain secure and operational.

Key provisions of the bill include a mandate for the state to notify critical infrastructure entities about known or suspected cyber threats. This notification process is designed to help these entities identify vulnerabilities and enhance their defenses without compromising proprietary information. By fostering communication between the state and private sector, the bill aims to create a more resilient infrastructure landscape.

However, the bill has sparked notable debates among lawmakers and stakeholders. Critics argue that the restrictions on software produced by companies headquartered in certain jurisdictions could limit competition and innovation in the tech sector. Proponents, on the other hand, emphasize the necessity of prioritizing security over potential economic drawbacks, especially in light of recent high-profile cyberattacks across the nation.

The implications of Senate Bill 378 extend beyond cybersecurity; they touch on economic and political dimensions as well. By prioritizing the protection of critical infrastructure, Tennessee positions itself as a leader in cybersecurity, potentially attracting businesses that value robust security measures. Conversely, the bill could face challenges from businesses concerned about regulatory overreach and the impact on their operations.

As the legislative process unfolds, experts suggest that the bill could set a precedent for other states grappling with similar security concerns. The outcome of Senate Bill 378 will likely influence how states approach cybersecurity in the future, balancing the need for security with the realities of a competitive economic landscape.

In conclusion, Senate Bill 378 represents a proactive step by Tennessee lawmakers to address the pressing issue of cybersecurity in critical infrastructure. As discussions continue, the bill’s fate will be closely watched, with potential ramifications for both state security and the local economy.
