Method — Runtime Verification

Definition, scope boundary, and structural model.

Definition

Runtime verification is the analysis of observed system executions against specified properties in order to derive verification information about those executions.

The model separates the property specification, execution trace, monitor evaluation, and verification verdict without prescribing a particular monitoring language, instrumentation mechanism, runtime framework, or enforcement procedure.

Model Classification

The runtime verification model is structured as a descriptive and analytical reference model.

It provides a framework for examining specification-based monitoring of concrete executions without defining exhaustive static verification, general testing methodology, implementation-specific monitoring architectures, or operational control procedures.

Scope Boundary

Included

Observation or recording of concrete system executions

Execution traces composed of events, states, values, or transitions

Explicit properties, requirements, assertions, or formal specifications used for monitoring

Monitor evaluation of execution traces against specified properties

Verification verdicts or other verification information derived from observed executions

Online and offline runtime-verification relations

Excluded

Exhaustive static verification independent of a concrete observed execution

General software testing without the runtime-verification relation

Implementation-specific monitoring frameworks or instrumentation mechanisms

Vendor-specific systems

Runtime enforcement or control actions as such

Operational safety or incident-response procedures

Structural Model

Property Specification

The explicit property, requirement, assertion, or formal specification against which execution behavior is evaluated.

Execution Trace

The observed sequence or structured record of events, states, values, or transitions produced by a concrete system execution.

Monitor Evaluation

The evaluation relation that processes relevant execution observations with respect to the specified property.

Verification Verdict

The verification information derived from the evaluated execution relative to the monitored property and the available observation state.

Structural Components

Property Specification

The explicit semantic condition that establishes what aspect of execution behavior is being monitored.

Execution Trace

The concrete behavioral evidence available to the runtime-verification process.

Monitor Evaluation

The structured comparison or interpretation of trace observations relative to the monitored property.

Verification Verdict

The resulting assessment state produced from the relation between the observed execution and the specified property.

Transferability

The runtime verification model is not limited to a specific execution platform or monitoring technology.

It can be applied across software, hardware, embedded, cyber-physical, autonomous, distributed, and other executing systems in which observable behavior can be assessed against explicit properties.

The model remains consistent by focusing on property specification, execution trace, monitor evaluation, and verification verdict rather than implementation-specific monitoring or enforcement mechanisms.
