Enhancing Cybersecurity Data Quality for CSIRTs: Preliminary Study Findings

Feasibility study on developing cybersecurity risk indicators through a questionnaire distributed to national CSIRTs, with 25 responses analyzed. Preliminary results highlight three primary sets of questions: general aspects, capacity, and incident-related queries. The study delves into challenges encountered and methods to enhance data quality.

  1. Improving the international comparability of statistics produced by csirts Developing Cybersecurity Risk Indicators panel 26th Annual FIRST Conference Aaron Martin

  2. Feasibility study design • Questionnaire developed to determine: • Can CSIRTs respond to these questions? • Would the data collected help produce quality statistical indicators? • Widely distributed to national CSIRTs • 25 responses • Analysis of results ongoing

  3. Preliminary analysis • Three sets of primary questions • General aspects of CSIRTs • Organisational capacity • Incidents • Feedback questions • Explaining non-responses • Additional information • Basis for calculations • Difficulties encountered • How to improve the questions

  4. General aspects • Accounting for more than one national CSIRT per country/economy • Classifying CSIRTs by constituency • IP addresses as an indicator of network size • Internet users as an indicator of network size • Understanding CSIRT data sources

  5. Capacity questions • CSIRT annual budget • Percentage of budget funded by government • FTEs employed by the CSIRT • FTEs employed for security incident handling • Technical skills • Incident reports handled without human intervention (i.e. automated) • Requests for assistance  dedicated action taken • Targeted mitigation (proactive notice) • Formal co-operation • Informal co-operation

  6. Incident-related questions • Phishing websites hosted in the CSIRT’s constituency • DoS attacks targeting the constituency • Defaced websites hosted in the constituency • Servers hosting malware • Servers directing to malware • Botnet C&C servers
