FISMA High Impact
FISMA High impact level applies to critical federal information systems where a security breach would result in severe or catastrophic adverse effects on organizational operations, assets, or individuals. High impact systems require ~370 NIST 800-53 baseline controls and the most rigorous security measures. Tyndora automates comprehensive control implementation, assessment, and continuous monitoring for High impact systems.
High Impact — Severe or Catastrophic Effect
Systems where loss of confidentiality, integrity, or availability would have severe or catastrophic adverse effects. Reserved for the most critical federal systems.
High Impact Characteristics
- Confidentiality: Severe/catastrophic effect if disclosed
- Integrity: Severe/catastrophic effect if modified
- Availability: Severe/catastrophic effect if disrupted
- Control Baseline: ~370 NIST 800-53 controls (High baseline, Rev 5)
Typical High Impact Systems
- ✓ Critical infrastructure systems
- ✓ Law enforcement and intelligence systems
- ✓ Emergency services and response systems
- ✓ Financial systems of national importance
- ✓ Systems with highly sensitive data
- ✓ National security related systems

NIST 800-53 Control Families
The FISMA High baseline draws from these NIST SP 800-53 families. Select any family to see representative controls and what each one requires.
Representative controls in plain language, not verbatim NIST text. The exact controls and enhancements that apply are set by the impact level; consult NIST SP 800-53B and the FedRAMP baselines for the authoritative set.
