service providers, or nation states [West-Brown 03]. Whomever it serves, the CSIRT must clearly identify the constituency to ensure that they are providing services to appropriate individuals. The majority (86%) of the CSIRTs participating in the CSIRT Organizational Survey stated that they did have an identified constituency. Some of the new and developing teams stated that they were still in the process of identifying their constituency. The types of constituencies identified by the survey participants are shown in Figure 11. Organizational Survey Participants Constituencies clients and customers 17% IP range or domain 10% parent or host organization 17% public 3% military organizations 26% university and research networks 20% government organizations 7% Figure 11: Constituencies of Survey Participants As would be expected, the educational sector CSIRTs identified their parent research network or university as their constituency. The military CSIRTs identified other areas of the military or specific military departments, and the information and communication CSIRTs identified their customers or supported IP ranges and domains as their constituency. The non-profit CSIRTs identified the public or their host organization as their constituency. It should be pointed out that a CSIRT does not just interact with its constituency. A CSIRT may also communicate with other CSIRT teams and security experts, individuals outside of the CSIRT who are reporting problems, representatives from law enforcement, or vendors. Many CSIRTs, if time permits and if their policies allow, will try to help those outside of their constituency when reporting problems. But the constituency is the formal group that the CSIRT provides service for according to its mission. 50 CMU/SEI-2003-TR-001
3.2.2 Mission Because of the wide variety of CSIRTs and the diverse constituencies they serve, there is no one standard mission that all teams proclaim. The majority of the CSIRTs participating in our survey stated that they have an identified mission statement and included that statement or an approximation. Most mission statements included references to • protecting and maintaining the security of constituent systems • managing and coordinating incident response activities • minimizing damage in the event of a security incident • educating the constituency on security issues and best practices Many teams define their mission on their main web page and in literature describing their services. Mission statements can easily be found for a large number of national and coordinating CSIRTs. It is more difficult to find mission statements for MSSP CSIRTs, as their web pages are devoted to the types of services that clients can purchase. An example of a national CSIRT mission can be seen on SingCERT’s “About SingCERT” page [SingCERT 03]: “Mission One Point of Trusted Contact Facilitate Security Threats Resolution Increase National Competency in IT Security” The roles and responsibilities of the team, the mission and goals that it has, and how the team will operate must be identified and refined as the CSIRT is being planned and developed. One thing we have also learned is that teams evolve over time. Effective CSIRTs must be able to adapt to changes in funding, mission, constituency, management, or staffing. This has happened to a number of teams, including the CERT/CC, AusCERT, and DFN-CERT, to mention a few. 3.2.3 Organizational Placement of the CSIRT There is no clear standard or consistent placement or location of a CSIRT within the organizational reporting structure of a host or parent organization. Current teams are positioned across a wide range of departments, including the information technology (IT) department, security department, and even the audit or compliance department. A CSIRT can also be its own department not located within any other area. It is difficult to determine where a team is located in the organization without looking at an organization chart or asking the team. For MSSP CSIRTs, you may be able to find the division the service is located in by looking at CMU/SEI-2003-TR-001 51
