Information about SIRT responsibilities and incident ownership is available in the SIRT On-Call Guide.

Incident Management and Review

As part of the incident management and review process the SIRT maintains a recurring meeting that takes place on Monday of each week. During this meeting all of the previous weeks incidents, and any incidents that are currently open are reviewed. The review process covers the incident’s scope, impact, the work performed to mitigate and remediate the incident, next steps, blockers, and current status. These meetings are also an opportunity to discuss mishandled incidents and process improvements.

Limited Access

Information about security incidents or investigations is considered limited access and is not shared with all team members by default. Security incidents are handled with appropriate confidentiality protocols to protect potentially sensitive information and maintain operational security.

The workflow for security incident handling is:

graph TD
    A[Security incident occurs] --> |Incident reported| B[SIRT automation creates a private project]
    B -->C[SIRT automation creates issue in new project]
    C -->D[Reporter added to the issue/project]
    D -->E[Other team members are added as needed*]

*A pre-defined list of team members are automatically added when the incident is ~severity::1.
