Incident Response & Escalation Protocols

Severity Levels

Impact Assessment Criteria

Consider these factors when classifying incidents:

• Number of Users Affected: 1 user, department, multiple departments, entire company
• Business Impact: Revenue impact, customer-facing, regulatory compliance, reputation
• Duration: Short-term vs. extended outage
• Workaround Availability: Can users continue working through alternate means?
• Security Implications: Data exposure, unauthorized access, compliance violations
• Time Sensitivity: Is there a critical deadline or time-bound business need?

Phase 1: Detection and Logging

1. Incident Reported: Via service desk, monitoring alerts, or direct communication
2. Initial Assessment: Gather basic information about the issue
3. Create Ticket: Log in IT service management system with all details
4. Assign Severity: Classify based on impact and urgency
5. Acknowledge Receipt: Confirm to reporter that incident is logged and being addressed

Phase 2: Initial Response

1. Route to Appropriate Team: Assign to correct technical team or specialist
2. Acknowledge SLA: Ensure response within defined SLA for severity level
3. Begin Investigation: Technical team starts troubleshooting
4. Document Actions: Record all troubleshooting steps and findings
5. Status Updates: Provide updates per communication plan

Phase 3: Escalation (if needed)

Escalate when:

• Incident cannot be resolved within SLA timeframe
• Technical expertise beyond current team is required
• Business impact is greater than initially assessed
• Vendor involvement is needed
• Multiple teams must coordinate response
• Management awareness and decisions are required

Phase 4: Resolution and Recovery

1. Implement Fix: Apply permanent or temporary solution
2. Verify Resolution: Test and confirm issue is resolved
3. Communicate Resolution: Notify affected users and stakeholders
4. Monitor Stability: Watch for recurrence
5. Document Resolution: Record root cause and fix in ticket

Phase 5: Post-Incident Review

For P1 and P2 incidents, conduct post-incident review within 48 hours:

1. Timeline of events from detection to resolution
2. Root cause analysis
3. Response effectiveness evaluation
4. Identification of preventive measures
5. Process improvement recommendations
6. Documentation of lessons learned

Technical Escalation Path

Management Escalation Path

Immediate Actions for P1 Incidents

1. 0-5 minutes:
   • Log P1 incident in ticketing system
   • Call IT Director immediately
   • Assemble incident response team via conference bridge
2. 5-15 minutes:
   • Assess scope and business impact
   • Initiate incident command structure
   • Notify CTO/CIO if warranted
   • Begin status page updates
3. 15-30 minutes:
   • Implement emergency workarounds if available
   • Engage vendors if needed
   • Notify affected business units
   • Establish communication cadence (hourly updates)
4. Ongoing:
   • Continue troubleshooting and resolution efforts
   • Provide regular status updates
   • Coordinate with business leadership
   • Document all actions and decisions

Incident Command Structure

For major P1 incidents, establish clear roles:

Security Incident Types

• Malware or ransomware infection
• Data breach or unauthorized access
• Phishing attack or social engineering
• Denial of service (DoS/DDoS)
• Insider threat or policy violation
• Lost or stolen device with company data
• System compromise or unauthorized changes

Security Incident Response Process

1. Identification:
   • Security alert or user report received
   • Log incident as P1 or P2 based on scope
   • Notify Security Team immediately
2. Containment:
   • Isolate affected systems from network
   • Disable compromised accounts
   • Block malicious IP addresses or domains
   • Preserve evidence for investigation
3. Eradication:
   • Remove malware or unauthorized access
   • Patch vulnerabilities
   • Reset compromised credentials
   • Verify systems are clean
4. Recovery:
   • Restore systems from clean backups
   • Gradually bring systems back online
   • Monitor for signs of persistent threat
   • Validate business operations
5. Lessons Learned:
   • Conduct post-incident review
   • Document attack vector and response
   • Implement preventive controls
   • Update security policies and training

Security Escalation and Notification

Security incidents require specific notifications:

Internal Communication

Status update frequency based on severity:

Status Update Template

All incident communications should include:

• Subject Line: [Incident] - [Brief Description] - [Status]
• Current Status: What is happening right now?
• Impact: Who/what is affected?
• Actions Taken: What have we done so far?
• Next Steps: What are we doing next?
• Estimated Resolution: When do we expect resolution? (if known)
• Workaround: Can users do anything to continue working?
• Next Update: When will we provide the next update?

External Communication

For incidents affecting customers or requiring public statement:

• All external communications must be approved by Legal and Executive Leadership
• Marketing/PR coordinates messaging
• Customer support provides approved talking points
• IT provides technical facts and timeline
• Avoid technical jargon; focus on business impact and resolution

When to Engage Vendors

• Issue is related to vendor product or service
• Internal troubleshooting has exhausted options
• Vendor-specific knowledge is required
• Software bug or defect is suspected
• Performance issue related to vendor service

Vendor Support Levels

Information to Provide Vendors

• Internal incident ticket number
• Customer/account number
• Product version and configuration
• Detailed problem description and symptoms
• Steps to reproduce the issue
• Troubleshooting already performed
• Error messages and log files
• Business impact and urgency

Workaround Strategies

When primary systems are unavailable:

• Alternative Systems: Use backup or redundant systems
• Manual Processes: Temporarily revert to manual workflows
• Reduced Functionality: Operate with limited features
• Cloud Alternatives: Leverage cloud-based alternatives
• Mobile Solutions: Use mobile apps when desktops unavailable

Critical System Recovery Priorities

Recovery order based on business impact:

1. Email and communication systems
2. ERP and financial systems
3. CRM and customer-facing systems
4. Core business applications
5. Collaboration and productivity tools
6. Administrative and support systems

Required Documentation During Incident

• Timeline of events with timestamps
• All troubleshooting steps performed
• Conference bridge attendance and participants
• Decisions made and decision-makers
• Communications sent to stakeholders
• Vendor interactions and case numbers
• System changes or configurations modified

Post-Incident Report

Required for all P1 and P2 incidents:

1. Executive Summary: Brief overview in business terms
2. Incident Details: What happened, when, who was affected
3. Timeline: Chronological sequence of events
4. Root Cause: Why did this happen?
5. Resolution: How was it fixed?
6. Business Impact: Quantify downtime, revenue impact, user impact
7. Response Assessment: What went well, what didn't?
8. Preventive Measures: How will we prevent recurrence?
9. Action Items: Follow-up tasks with owners and due dates

On-Call Rotation

IT maintains 24/7 on-call coverage:

• Primary On-Call: IT Manager or Senior Engineer (rotating weekly)
• Secondary On-Call: IT Director (escalation point)
• Tertiary On-Call: CTO/CIO (critical incidents only)

On-Call Responsibilities

• Monitor phone/email for critical alerts
• Respond to P1 incidents within 15 minutes
• Triage and escalate as needed
• Coordinate vendor engagement if required
• Document all actions and handoff to day team

After-Hours Contact Methods

• PagerDuty: Automated alerting and escalation
• IT Leadership Mobile: Direct contact numbers in emergency contact list

Incident Management KPIs

Monthly Incident Reports

IT Managers must provide monthly reports including:

• Total incidents by severity and category
• Top 5 incident types and trends
• SLA compliance by severity level
• Average MTTA and MTTR
• Major incidents summary and lessons learned
