Annual cybersecurity assessments must be conducted by qualified third parties beginning in 2026. Self-assessments no longer satisfy directive requirements for covered operators. Organizations must identify qualified assessment providers and schedule assessments meeting the annual requirement.

EPA water system requirements

The Environmental Protection Agency clarified cybersecurity requirements for public water systems through updated guidance and enforcement expectations. While EPA lacks direct cybersecurity regulatory authority, agency officials indicated cybersecurity deficiencies may constitute violations of Safe Drinking Water Act sanitary survey requirements. This interpretation creates effective cybersecurity mandates for water systems.

State drinking water programs received EPA guidance for incorporating cybersecurity into sanitary surveys. Survey teams will assess cybersecurity practices as part of routine water system evaluations. Systems with significant cybersecurity deficiencies may face compliance actions including required corrective measures and potential enforcement.

EPA's Water Sector Cybersecurity Task Force published best practices for water utility cybersecurity. While formally voluntary, these practices establish expectations that inform sanitary survey assessments. Water systems should implement task force recommendations to avoid compliance findings.

Small water systems face particular challenges meeting cybersecurity expectations with limited resources. EPA and state programs offer technical assistance for small system cybersecurity improvement. Systems should use available assistance programs while implementing foundational security measures.

Financial sector cybersecurity evolution

Financial regulators continued strengthening cybersecurity expectations during 2025 with focus on third-party risk management and operational resilience. The Federal Reserve, OCC, and FDIC interagency guidance on third-party risk management establishes thorough due diligence and monitoring requirements. Financial institutions must demonstrate effective oversight of technology vendors and service providers.

NYDFS Cybersecurity Regulation second amendment compliance deadlines occur throughout 2026. New York-regulated financial services companies face enhanced requirements for board oversight, access controls, and incident response. The November 2025 deadline for third-party service provider requirements marked the first phase with additional requirements following.

SEC cybersecurity disclosure requirements prompted financial services firms to enhance board-level cyber risk governance. Mandatory incident disclosure creates accountability pressure for cybersecurity investment. Boards now engage directly with cybersecurity matters given disclosure and liability implications.

PCI DSS 4.0 full enforcement began in 2025 with enhanced requirements for payment card security. Organizations processing payment card data must implement updated controls including customized security approaches and targeted risk analysis. Payment security programs require updating for 4.0 compliance.

Healthcare critical infrastructure protections

Healthcare cybersecurity received increased federal attention following continued ransomware attacks against hospitals and health systems. HHS published updated guidance reinforcing HIPAA Security Rule requirements and announcing enhanced enforcement focus on cybersecurity compliance. Healthcare organizations should anticipate increased audit and enforcement activity.

The Healthcare Cybersecurity and Resiliency Act introduced in Congress would establish mandatory cybersecurity requirements for healthcare organizations. While not yet enacted, the legislation signals direction for healthcare cybersecurity policy. Organizations should track legislative progress and prepare for potential requirements.

Healthcare information sharing improved through expanded Health-ISAC participation and improved threat intelligence sharing mechanisms. Organizations not participating in healthcare sector information sharing should evaluate membership benefits. Sector-specific threat intelligence improves defensive capabilities.

Medical device cybersecurity requirements established by FDA premarket guidance affect healthcare organizations acquiring new connected medical devices. Purchasing requirements should include cybersecurity specifications aligned with FDA expectations. Legacy device risks require assessment and mitigation planning.

State and local government requirements

State cybersecurity requirements for local governments expanded during 2025 with multiple states establishing mandatory security standards. Local governments receiving state funding or operating critical services face baseline security requirements. States now condition grants and assistance on cybersecurity compliance.

State cybersecurity grant programs funded by the Infrastructure Investment and Jobs Act require cybersecurity planning as a condition of funding. Grant recipients must develop and implement cybersecurity plans meeting state-established standards. Local governments should align cybersecurity investments with grant requirements.

Multi-state information sharing organizations expanded coverage providing threat intelligence and incident response assistance to state and local governments. MS-ISAC membership grew substantially providing smaller governments access to security resources otherwise unavailable. Non-member governments should evaluate membership benefits.

Election infrastructure security received continued focus ahead of the 2026 election cycle. Election officials face requirements for voting system security, voter registration database protection, and election night reporting security. Election administrators should verify compliance with applicable security requirements.

International critical infrastructure coordination

US-EU critical infrastructure cybersecurity coordination advanced through structured dialogs and information sharing arrangements. Cross-border incident coordination procedures improved enabling faster response to threats affecting infrastructure in multiple jurisdictions. Organizations with transatlantic operations benefit from improved coordination mechanisms.
