What Is FISMA?
What Is FISMA?
FISMA originally stood for the Federal Information Security Management Act and was updated in 2014 by the Federal Information Security Modernization Act. It is a U.S. law that requires federal agencies and the organizations that support them to develop, document, and implement programs to protect government information systems.
FISMA establishes the framework for managing federal cybersecurity risk and is implemented through standards and guidelines developed by NIST, particularly the NIST SP 800-53 security control catalog.
Under FISMA, agencies and contractors must implement security controls, continuously monitor systems, and demonstrate that risks are managed through documented and enforceable safeguards.
Why It Matters
FISMA applies to federal agencies as well as contractors, service providers, and vendors that operate systems on behalf of the U.S. government.
Organizations must demonstrate that their systems:
- Protect the confidentiality, integrity, and availability of federal information
- Enforce secure system configurations
- Control and monitor system changes
- Continuously assess security controls
- Maintain evidence that safeguards remain effective over time
FISMA compliance is assessed through security authorization processes and ongoing monitoring programs. Organizations unable to demonstrate operational controls may face remediation requirements, system restrictions, or loss of federal contracts.
What the Standard Says
From NIST SP 800-53 Rev. 5 — Configuration Management (CM-6):
“The organization establishes and documents configuration settings for information technology products employed within the system using security configuration checklists that reflect the most restrictive mode consistent with operational requirements.”

This control forms part of the security control framework used to implement FISMA requirements for federal systems.
What FISMA Requires
FISMA relies heavily on NIST security controls, particularly those related to configuration management, access control, system integrity, and continuous monitoring.
Organizations must implement safeguards such as:
- Defined security configuration baselines
- Controlled configuration changes
- Least functionality across systems and services
- Continuous monitoring of security posture
- Risk assessments and vulnerability management
- Documented governance and oversight
These controls must remain active and measurable throughout the lifecycle of the system.
FISMA Implementation Guidance
Organizations operating federal systems should be able to demonstrate the following:
☐ Security baselines are defined and applied to all in-scope systems
☐ Configuration standards align with recognized benchmarks or agency guidance
☐ Change control processes govern modifications to system configurations
☐ System configurations are continuously monitored for drift
☐ Unauthorized changes trigger investigation and remediation
☐ Vulnerability scanning and risk assessments are performed regularly
☐ Audit logs support monitoring and incident investigation
☐ Security controls remain enforced throughout system operation
How CalCom Helps
CalCom Hardening Suite helps organizations enforce configuration controls required under the NIST security framework used by FISMA.
With CalCom, teams can:
- Enforce hardened configuration baselines across servers
- Detect configuration drift in real time
- Restrict unauthorized configuration changes
- Generate audit-ready reports aligned with NIST control requirements
- Maintain continuous visibility into system configuration posture
These capabilities support organizations preparing for security assessments and maintaining ongoing compliance with federal security requirements.
