Direct answer
Before an incident, identify the internal owner and verified provider contacts for each important service, including escalation and out-of-hours paths. Test the process with an exercise and keep the information current.
Identify the service and contract owner
For an identity provider, record which applications depend on it, the internal service owner and the contractual support channel. Avoid relying on a single employee's personal contact list; maintain a controlled, accessible record.
Reference: NIST SP 800-61 Rev. 3: Incident Response.
Verify the channels
Use established provider documentation or account records to confirm security reporting, support and escalation contacts. Document availability, expected response arrangements and who can open a case. A contact in an unexpected incident email should be verified independently.
- Record primary and backup internal contacts.
- Identify relevant account or contract identifiers without storing credentials.
- Review channels after provider or ownership changes.
Define shared decisions
Agree who can revoke integration access, pause a service or communicate with customers. Determine what evidence can be shared and how sensitive logs will be transferred. A vendor may control its infrastructure while the customer controls identities and configuration.
Reference: NIST SP 800-61 Rev. 3: Incident Response.
Exercise and update
Walk through a simulated provider outage or credential exposure and check whether contacts and authorities are usable. Assign gaps and dates for correction. Preserve the exercise outcome securely without exposing sensitive operational details broadly.
Assessment limits
Contact information and provider processes can change. A documented channel does not guarantee response time or determine legal notification requirements.
Frequently asked questions
Can a vendor handle the whole incident?
Responsibilities vary. Identify the decisions and controls owned by both the vendor and your organization.
Should we use a contact from a surprising email?
Verify it using the provider's established channel before sharing sensitive information or acting on instructions.
