FISMA

FISMA (Federal Information Security Management Act, now commonly referenced as the Federal Information Security Modernization Act) is a United States federal law that establishes requirements for protecting information and information systems used or operated by federal agencies and, in many cases, by their contractors and service providers.

In practice, FISMA requires covered organizations to implement, document, and maintain an information security program that is based on risk management. For industrial and manufacturing environments that provide products or services to U.S. federal agencies, this often includes both IT and OT systems that store, process, or transmit federal information, such as plant-level control systems, MES instances, or cloud services supporting regulated programs.

Key elements of FISMA

Common elements of a FISMA-governed information security program include:

• Classifying information systems by impact level (low, moderate, or high) using NIST guidance
• Selecting and tailoring security and privacy controls, typically from NIST SP 800-53
• Implementing and documenting those controls across relevant systems and environments
• Conducting security assessments and ongoing monitoring of system security posture
• Maintaining system security plans, plans of action and milestones (POA&Ms), and related records
• Reporting on security status and incidents through defined federal channels

Relation to NIST SP 800-53 and industrial systems

FISMA is the legal driver that leads many organizations to use NIST SP 800-53 as the primary catalog of controls for federal information systems. In industrial and manufacturing settings, this can affect:

• Enterprise IT systems that integrate with MES, ERP, LIMS, or quality systems used for federal programs
• Operational technology (OT) assets, such as SCADA and control systems, when they handle federal data or connect to federally scoped networks
• Third-party hosting or managed services supporting regulated production or maintenance activities

Under FISMA, organizations document how applicable controls are implemented and how evidence (such as configuration baselines, access reviews, change records, and incident logs) is maintained for assessment and oversight.

Common confusion

• FISMA vs. NIST SP 800-53: FISMA is the law that mandates federal information security programs. NIST SP 800-53 is a control catalog commonly used to satisfy FISMA requirements, but it is not the law itself.
• FISMA vs. agency-specific policies: Individual agencies may issue additional security policies or baselines. These are built on top of FISMA requirements and NIST guidance rather than replacing them.

Use in regulated manufacturing environments

Manufacturers working on federal contracts, especially in defense, aerospace, and critical infrastructure projects, may be required to align their information systems and cybersecurity practices with FISMA. This can influence how they design network segmentation for OT, control access to production data, integrate MES or historian systems with enterprise networks, and retain documentation needed for federal security assessments.
