Question

A developer at your company notices a secret scanning alert flagging an AWS access key that was committed to a repository three weeks ago. The developer confirms the key is real and is still active in the AWS account. Under time pressure, they consider simply dismissing the alert in GitHub as 'used in tests' so the CI dashboard turns green. As the security lead, what is the most important thing you must communicate about the implications of this action?

Accepted Answer

Dismissing the alert only changes its status in GitHub and does nothing to invalidate the exposed credential; the key must be rotated/revoked at AWS and the exposure remediated regardless of alert status.

Answer

Dismissing the alert automatically revokes the exposed AWS key through GitHub's partner integration, so no further action is needed once dismissed.

Answer

Dismissing the alert permanently deletes the secret from the repository's Git history, eliminating the exposure automatically.

Answer

Dismissing the alert prevents that same secret pattern from ever being scanned again across the entire organization, reducing future false positives.
