Detailed Answer
Do wire Inspector findings to EventBridge for automated response; do not rely on it for non-AWS or on-prem assets, which it does not see.
The anti-pattern usually comes from treating the tool as a checkbox rather than a control people have to live with. A gate that is too loud gets bypassed; a gate that blocks on things nobody can fix gets disabled; a suppression with no expiry becomes a permanent blind spot. The best practice above is the version that survives contact with a real team under delivery pressure.
Generally: make the signal trustworthy (low noise), make the required action clear and achievable, give an honest escape hatch for genuine exceptions, and review suppressions and thresholds on a schedule so the configuration does not quietly rot into "always green, never useful."

Interview Tip
Pair every best practice with the failure it prevents — it shows you learned it the hard way, not from a doc.
