IDS/IPS Signature Set Coverage Gap Ratio calculator computes Coverage Gap Ratio in dimensionless using the defined engineering formula and the input values provided. Coverage Gap Ratio is expressed in dimensionless. No universal acceptance threshold is defined by this calculator.
Worked Example
Verified calculation
Given:
- Total Known Threat Patterns = 10000
- Threat Patterns Covered by Signatures = 8500
Expected Result:
- Coverage Gap Ratio = 0.15
Engineering Interpretation:
Under the given input conditions, the calculated result is: Coverage Gap Ratio = 0.15 dimensionless.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
Formula / Method
coverage gap ratio = max(0.0, min(1.0, (total known threat patterns - threat patterns covered by signatures) / total known threat patterns))Formula family: formula_cybersecurity_idsips_signature_set_coverage_gap_analyzer
