Less than half perform forensic evidence collection, tracking and tracing intruders, and legal investigations. • When the CSIRT is located within the IT department, 100% perform incident handling and IDS monitoring. 92% produced advisories and 83% perform artifact analysis, virus handling, and security policy development. • When the CSIRT is located within the security team, 75% perform forensic evidence collection, pursue legal investigations, and provide a hotline service and a technical watch service. 25% perform penetration testing, vulnerability scanning, vulnerability assess- 70 Any services not mentioned were only listed by a small number of the teams. 68 CMU/SEI-2003-TR-001
ments, or training. None perform security configuration administration, IDS monitoring, or system and network monitoring. Profiling of the teams by sector and services provided the following results: • Banking and finance: CSIRTs: 100% perform incident handling, artifact analysis, virus handling, IDS monitoring, technical document development, security policy development, forensic evidence collection, tracking and tracing of intruders, and legal investigations. • Education: CSIRTs: 100% perform incident handling and IDS monitoring; 83% perform artifact analysis, virus handling, advisory production, security policy development, training, and forensic evidence collection. • Information and communication: CSIRTs: 100% perform incident handling and forensics analysis; 75% perform a technology watch service, produce advisories, perform security policy development, track and trace intruders, and pursue legal investigations. • Military CSIRTs: 88% perform incident handling, 75% produce advisories and perform virus handling, and 63% provide a hotline service. None of the military teams participating in the survey provide penetration testing and only 22% perform vulnerability scanning, assessments, or forensic evidence collection. • Other commercial CSIRTs: 100% perform incident handling, virus handling, network and system monitoring, technology watch, security policy development, and security product development and produce advisories. • Non-profit CSIRTs: 66% provide training, technical document development, advisory publication, and a hotline service. None perform penetration testing, vulnerability scanning, security configuration administration, or legal investigations. Profiling of the teams by CSIRT model and services produced the following results: • Ad hoc teams: 100% perform incident handling; 75% perform virus handling. None perform penetration testing, vulnerability scanning, vulnerability assessments, or security configuration administration. Only 25% perform a technology watch service or monitor IDS. This seems fitting with the nature of such teams not to be involved in proactive or security quality management services. • Coordination centers: 100% perform incident handling, technology watch services, advisory production, technical document production, security policy development, and tracking and tracing intruders. This seems to fit with the focus on coordination and being proactive. • Centralized CSIRTs: 90% perform incident handling; 80% perform advisory production and virus handling. Only 10% perform penetration testing. • Combined teams: 100% perform incident handling and artifact analysis; 80% perform security policy development. CMU/SEI-2003-TR-001 69
