Connect delivery to the SOC and SIRT

Define the functions behind the names

A security operations center, or SOC, commonly monitors security signals, investigates alerts, and escalates suspected incidents. A security incident response team, or SIRT, coordinates the response to security incidents. CSIRT is another common name for this response function.

Organizations divide these functions differently. The same people may perform both. An external provider may supply part of the service. Do not infer coverage or authority from an acronym. Record monitoring hours, escalation routes, decision rights, and response commitments.

FIRST’s CSIRT framework describes services that a response team can provide. NIST connects incident response with broader cybersecurity risk management. Use these references to define your responsibilities and interfaces. FIRST framework, NIST incident response.

Include AI development in the detection scope

A software delivery system has identities, repositories, runners, registries, integrations, and deployment credentials. Agents add tool calls and model-provider data flows. Include these boundaries in the security design.

Select events that support defined detections. Examples include unexpected repository access, privilege changes, unusual artifact publication, and deployment from an unapproved identity. Connect records with timestamps, actor identities, resource identifiers, and immutable artifact digests where available.

Protect those records. Audit access, retention, clock quality, and collection failures affect the investigation. A development run log and a cloud audit log answer different questions. Neither is automatically a complete incident record.

Prepare a handoff before the incident

Define who can revoke a token, isolate a runner, pause deployment, or restore a service. Service owners explain operational consequences. Security responders coordinate investigation and containment. Relevant privacy, legal, and business owners assess notification duties for the actual situation.

Notification requirements depend on the incident and applicable obligations. Include the appropriate decision owner early. Do not let an AI summary make that determination or delay an established escalation route.

Work through a fictional token incident

At 14:05 UTC, the SOC detects a build identity reading an unexpected repository. At 14:08, the repository owner confirms that no approved job explains the activity. Whether source code left the environment remains unknown.

The response team preserves audit records and the relevant runner evidence. An authorized owner revokes the affected credential and stops the suspect execution path. These actions follow the organization’s response procedure and account for service impact.

Deleting the leaked token from a file is insufficient. The credential can remain valid elsewhere. Rebuilding a runner is also insufficient if the identity remains compromised. Investigate issued artifacts, downstream access, and other credentials within the plausible scope.

Before restoring delivery, verify the identity, runner, artifact provenance, and required access boundaries. Record what is still unknown. A successful build alone does not establish that the delivery environment is trustworthy.

Return the findings to engineering

Convert confirmed causes into owned work: shorter credential lifetime, narrower access, runner isolation, detection changes, or a regression test. Validate the correction and exercise the handoff again.
