Coordinating effectively with vendors during an incident requires clear communication channels and well-defined processes. These steps help ensure vendors can quickly and efficiently assist when issues arise.

Vendor Communication Process

Once an incident is analyzed, quick coordination with vendors is essential to minimize the impact. Use secure, dedicated channels to share important details. These should include:

• Primary and backup contact methods for both technical and management teams
• A system to classify incident severity that aligns with the vendor's response capabilities
• Documented procedures to track communications and decisions
• Secure methods for sharing sensitive incident data

Joint Response Planning

Create a response strategy that aligns your internal team's efforts with the vendor's capabilities. The plan should:

• Clearly outline roles and responsibilities for both internal and vendor teams
• Define escalation paths for critical decisions or challenges
• Include shared timelines for key response activities and milestones
• Leverage real-time collaborative tools for seamless coordination

Status Updates to Management

Provide regular updates to management, focusing on the business impact and progress toward resolving the issue. Updates should cover:

1. A summary of the incident, including its scope, severity, and any effects on critical systems
2. An overview of actions taken by internal teams and vendors, highlighting milestones and next steps
3. Details on any additional resources needed to speed up resolution

Set update intervals based on the severity of the incident to ensure information remains timely, accurate, and actionable.

Incident Control Measures

Managing third-party incidents effectively requires swift action to limit damage while keeping business operations running. This involves close coordination between internal teams and external vendors. Documenting these actions is key to moving toward long-term resolution and system recovery.

Control Actions

Take immediate steps to contain the incident and protect systems:

• Isolate impacted systems but keep necessary vendor links active.
• Limit vendor access while maintaining critical connections.
• Monitor shared data interfaces with stricter validation rules.
• Tighten filtering for vendor traffic and API calls.

Keep an eye on system performance to avoid unexpected disruptions.

Temporary Solutions

When immediate controls aren’t enough, use temporary measures to keep operations running:

• Set up alternative paths for essential vendor services.
• Use supervised manual processes to replace automated workflows.
• Increase internal resources to handle extra workload.

Make sure temporary solutions are logged with clear timelines and rollback plans.

Response Documentation

Keep detailed and up-to-date logs throughout the response process. These should include:

1. Action Records
   Record each control measure with a timestamp, noting the action taken, responsible teams, affected systems, and results.
2. Decision Documentation
   • Include risk assessments, alternative options, and approval details.
