RS.CO-4: Stakeholder Response Coordination
When a security incident strikes, siloed response efforts fall apart. NIST Cybersecurity Framework control RS.CO-4 ensures your organization coordinates with internal and external stakeholders—customers, regulators, vendors, and partners—using pre-established response plans. This control transforms reactive chaos into orchestrated, compliant incident management.
What this means
RS.CO-4 requires that your incident response activities involve coordinated communication and action with all relevant stakeholders according to documented response plans. Stakeholders may include executives, legal teams, customer support, law enforcement, regulators, and business partners. Coordination must be planned in advance—not improvised during an incident—so response roles, escalation paths, notification timelines, and communication channels are clear before a breach occurs.
How to comply
- 1.Document a formal incident response plan that identifies all internal and external stakeholders and their roles during incidents.
- 2.Define escalation procedures, notification timelines, and communication protocols for each stakeholder group.
- 3.Establish pre-approved communication templates and contact lists to enable rapid, consistent outreach.
- 4.Assign a coordinating authority or incident commander to orchestrate response activities across all stakeholders.
- 5.Conduct tabletop exercises and simulations that include relevant stakeholders to test coordination procedures.
- 6.Review and update coordination procedures annually or after any major incident to capture lessons learned.
