Info

ased on a sampling of CSIRTs done via survey; our own research, interviews, and observation 6 ; and input and observations from others in the field. This document provides information about CSIRTs at a particular point in time—June 2002 through August 2003. Although some of the information is time constrained, the resulting information can still provide useful insights for organizations planning to create or expand an incident response capability or formal CSIRT. The focus of the document is the collection of data to understand how CSIRTs are structured and how they operate and to determine if there are any trends particular to a certain type of CSIRT or CSIRT sector. This document does not try to make any recommendations for best practices or processes in day-to-day CSIRT activities. It is simply synthesizing and presenting the information gathered. This document also does not include a review or discussion of broader security standards such as those from the International Standards Organization (ISO) or British Standards (BS). 1.3 Intended Audience The primary audience for this document includes the general CSIRT community who may want a better understanding of the structure and functions of existing teams. It will also benefit those individuals and organizations looking to join the CSIRT community. It is specifically targeted at those managers and individuals who are involved in the process of creating and operating a CSIRT or managing incident activity. This may include • Organizational Chief Information Officers (CIOs), Chief Security Officers (CSOs), and Information Systems Security Officers (ISSOs) • project leaders and members charged with creating a team • CSIRT managers • CSIRT staff • IT managers As well as being a useful reference for higher management levels and all CSIRT staff, this document can also be of use to other individuals who interact with CSIRTs and would benefit from an understanding of CSIRT organizational issues. This may include members of the 6 All contributions were provided voluntarily. 4 CMU/SEI-2003-TR-001
• CSIRT constituency • law enforcement community • systems and network administrator community • CSIRT parent organization or other departments within the parent organization such as − legal − media or public relations − human resources − audits and risk management − investigations and crisis management 1.4 Use of this Document This document was developed for use as both a stand-alone document and as a companion document to two other reports from the Software Engineering Institute: • Handbook for CSIRTs, CMU/SEI-2003-HB-002 [West-Brown 03] • Organizational Models for CSIRTs, CMU/SEI-2003-HB-001 7 As a stand-alone document, this report can be used as an information reference by anyone interested in CSIRT activities. The document also provides information on • the evolution and development of teams • the types and numbers of teams existing today • preliminary statistics on the types of CSIRT structures and processes gathered through the pilot survey • current articles, publications, and training that may be of interest to anyone involved in incident response activities • some current projects that teams may want to join or review • resources that teams may want to use or review • current challenges and issues that are being addressed by the CSIRT community This document can be used in conjunction with the other two reports mentioned above to provide guidance for teams on the options for organizing and operating a CSIRT. It can be used at the early stage of CSIRT development to provide ideas for organizational structures and service offerings. It can also be used to help gather management buy-in and support and, after support has been gathered, to strategically plan and develop a team. Looking at what existing teams are doing can provide ideas for other teams and help existing teams plan their 7 Organizational Models for CSIRTs will be published in the fall of 2003.
