Core Team Roles & Responsibilities

Every incident response team needs these core roles. In smaller organizations, individuals may fill multiple roles. The key is clear accountability before an incident occurs.

Incident Commander

Internal

Senior executive (CISO, CIO, or VP) with authority to make decisions and allocate resources. Single point of accountability for the entire response.

Key Responsibilities:

  • • Overall incident ownership and decision-making authority
  • • Resource allocation and budget approval
  • • Executive and board communication
  • • Final approval on external communications
  • • Post-incident review leadership

IT/Security Lead

Internal

Technical leader who coordinates containment, investigation, and remediation activities. Interface between technical teams and leadership.

Key Responsibilities:

  • • Coordinate technical response activities
  • • System isolation and containment decisions
  • • Interface with external IR firm (if engaged)
  • • Technical evidence preservation
  • • Remediation planning and execution

Legal Counsel

Internal or External

Attorney experienced in privacy law, data breach notifications, and cyber liability. Critical for attorney-client privilege protection.

Key Responsibilities:

  • • Legal strategy and liability assessment
  • • Regulatory notification requirements (GDPR, HIPAA, CCPA)
  • • Attorney-client privilege protection
  • • Review all external communications
  • • Litigation preparation and defense

Communications/PR Lead

Internal or External

Manages internal and external messaging. Controls narrative and protects reputation. Experience with crisis communications essential.

Key Responsibilities:

  • • Draft customer notification letters
  • • Prepare media statements and Q&A
  • • Internal employee communications
  • • Social media monitoring and response
  • • Reputation recovery strategy

HR Representative

Internal

Essential if employee data is compromised or insider threat is suspected. Handles internal personnel matters and employee notifications.

Key Responsibilities:

  • • Employee data breach notifications
  • • Insider threat investigation support
  • • Staff scheduling during incident
  • • Employee assistance programs
  • • Disciplinary actions (if applicable)

Forensic Investigator

Usually External

Specialized digital forensics expert. Conducts technical investigation, determines root cause, and preserves evidence for legal proceedings.

Key Responsibilities:

  • • Forensic imaging and evidence collection
  • • Root cause and attack vector analysis
  • • Scope determination (what data was accessed)
  • • Malware analysis and attribution
  • • Expert testimony preparation

RACI Matrix: Who Does What

RACI defines Responsible, Accountable, Consulted, and Informed roles for each activity. Clear accountability prevents confusion during crisis.

Activity Commander IT/Sec Lead Legal Comms HR Forensics
Initial containment A R I I I C
Evidence preservation I A C I I R
Regulatory notification A C R C I C
Customer communication A I C R I I
Technical remediation I R I I I A
Post-incident review R C C C C C
R = Responsible (does the work)
A = Accountable (final authority)
C = Consulted (input required)
I = Informed (kept updated)

Internal vs External IR Resources

Most organizations need a combination of internal and external resources. Here's a decision framework for when to engage external IR firms.

✓ Hire External IR Firm When:

  • • Limited internal forensic expertise
  • • Severe breach (regulatory scrutiny expected)
  • • Ransomware or advanced persistent threat
  • • Litigation risk is high
  • • Objectivity required (insider threat suspected)
  • • Insurance requirement

△ May Handle Internally When:

  • • Minor incident with clear containment
  • • Strong internal security team (5+ FTE)
  • • No regulatory notification required
  • • Previous incident experience
  • • Existing forensic tooling in place
  • • Low litigation probability

Cost Comparison

Model Cost Advantages Disadvantages
Internal Team $200K-500K/year
(salaries + tools)		 Institutional knowledge, immediate availability Expensive, capacity limited, may lack objectivity
Retainer Agreement $50K-200K/year Guaranteed response, pre-negotiated rates, relationship Ongoing cost, may not use
Per-Incident $50K-300K/incident Pay only when needed, no ongoing commitment Longer response times, higher rates, no relationship

Recommendation

Most mid-sized organizations benefit from a hybrid model: internal team for first-responder containment and coordination, with external IR retainer for forensic investigation and regulatory expertise. This provides cost efficiency while ensuring access to specialized skills when needed.
