Computer Security Incident Response Team Effectiveness: A Needs Assessment.

Area of Science:

• Cybersecurity
• Information Security Management
• Incident Response

Background:

• Computer security incident response teams (CSIRTs) are critical for national security and economic stability.
• CSIRTs often operate under time constraints, ad hoc conditions, and in close cooperation with other entities, increasing the likelihood of performance issues.

Purpose of the Study:

• To assess the extent to which CSIRTs encounter problems under their typical working conditions.
• To identify areas requiring improvement within CSIRT operations through a comprehensive needs assessment.

Main Methods:

• Development of an incident response needs model with four assessment categories: Organization, Team, Individual, and Instrumental.
• Conducting a literature review to compile a list of challenges and needs affecting CSIRT performance.
• Performing semi-structured interviews with Dutch CSIRT coordinators and members to validate findings and identify practice gaps.

Main Results:

• The needs assessment model provides a framework for understanding CSIRT challenges.
• A comprehensive list of factors influencing CSIRT performance was identified through literature review and interviews.
• Gaps between current and desired incident handling practices in Dutch CSIRTs were identified.

Conclusions:

• The study confirms that CSIRTs face significant challenges impacting their effectiveness.
• The developed model and identified needs offer a basis for improving CSIRT performance.
• Potential solutions for enhancing incident response capabilities are discussed, addressing organizational, team, individual, and technical aspects.
