Execution Chain

An execution chain is the sequence of automated actions triggered across systems to complete a task.

Definition

An execution chain is a sequence of automated actions triggered across multiple systems to complete a task. Each step may appear legitimate on its own, but the combined chain may introduce unexpected risk.

Why It Matters

Security teams often inspect events individually. Execution chains reveal how ordinary actions can combine into high-impact outcomes across infrastructure.

Example

A finance automation updates a record in an ERP, which triggers an API call to billing, then a report refresh in analytics, and finally a notification in Slack.
