Info

3.7.5.1 Data Fields Many CSIRTs have developed an incident reporting form to capture the type of information that helps them to identify the “who, what, when, where, and how” of some activity that is being reported. A variety of incident reporting forms (or templates) have been developed by different organizations and a few examples are referenced in Table 11. Examples of these forms have been included in Appendix E. Some CSIRTs may make their incident reporting forms available for public download and use by anyone wishing to report an incident to them. Other internal teams 94 may place their forms on intranets or include them as part of procedures or guidelines for reporting.

ISBN 0-596-00130-4 Kruse & Heiser Computer Forensics-Incident Response Essentials, ISBN 0-201-70719-5 CERT/CC http://www.cert.org/reporting/incident_form.txt Looking at these incident reporting forms, and others that are available or accessible from the Internet, we can see a standard set of data fields used to collect critical incident information: • contact information of the individual(s) reporting and/or contact information for other sites involved in the activity − name − email address − address − phone (direct dial, mobile/cellular, fax) • organization reporting incident • organization that is the victim of the incident • time of incident and corresponding time zone 94 By “internal teams” we mean CSIRTs who only serve their internal organization or a specific group or department in their organization and who have no external appearance outside their organization. 92 CMU/SEI-2003-TR-001
• time of report and corresponding time zone • time of discovery of incident and corresponding time zone • description of problem or report (summary, technical details) • type of system(s) involved or affected (owner, mission) • IP address(es) of involved hosts (source and destination of attacks or scans) • operating system (versions, patch level, applications installed) of hosts involved • actions taken (planned), mitigation strategies, resolution • involvement of law enforcement In addition to the list above there are often check boxes for identifying • the specific type of activity (probe, scan, break-in, virus, denial of service, etc.) that is being reported • whether the activity is currently ongoing or has stopped (i.e., was discovered after the fact) • questions to gauge the scope of the incident, extent of the damage, severity of the threat, and cost of the incident • the time zone and/or geographic location of system(s) involved (especially helpful when tracking or handling widespread incidents that span multiple time zones and affect many systems) • any other sites or organizations that may have been notified Each CSIRT will need to determine the information that is most appropriate to collect and record, depending on their mission and goals, the needs of the constituency they are supporting, and/or any regulatory requirements that may be imposed—and having tools to support the management of this information is a critical need for an effective CSIRT. Most teams need to customize existing products to meet their functionality requirements. Teams also need to identify how long they retain information about their incident reports. Some teams will keep information for short periods of time (months), while others may keep information for several years. 95 Different types of teams for different sectors may have various legal requirements that impact how long they can retain information. Although currently there are no widely accepted standards used by the CSIRT community to record and track CSIRT data, there is ongoing work in the IETF to develop standard data 95 The CERT/CC has kept an archive of all incident reports handled since the team was established in 1988.
