Info

In September 2003, the U.S. Department of Homeland Security (DHS), in conjunction with Carnegie Mellon University, announced the formation of the United States Computer Emergency Response Team (US-CERT). The main goals of the US-CERT will be to work with public and private sectors to • improve warning of and response to incidents • increase coordination of response information • reduce vulnerabilities • enhance prevention and protection efforts [US-CERT 03] “The US-CERT will begin as a partnership between the National Cyber Security Division (NCSD) within DHS and Carnegie Mellon’s CERT/CC. The US-CERT will grow to include other partnerships with private-sector security vendors and domestic and international organizations. These groups will work together to coordinate national and international efforts to prevent cyber attacks, protect systems, and respond to the effects of cyber attacks across the Internet” 47 [SEI 03]. 2.3.8 Other Initiatives in CSIRT Development and Evolution In 1995 a working group on Guidelines and Recommendations for Incident Processing (GRIP) was formed by the Internet Engineering Task Force (IETF). Its purpose was to develop guidelines for providing consistent information about CSIRTs to those internal and external to a team’s constituency. 48 The GRIP Working Group published RFC 2350, “Expectations for Computer Security Incident Response Teams as Best Current Practice” [Brownlee 98]. This Request for Comment (RFC) documented recommendations for what teams should publish about themselves and explained why this information would be useful for users of a CSIRT. As intruders make more use of home users’ computer systems, CSIRTs today are struggling to figure out ways to interact with this type of constituency. Some interesting public outreach projects and services are currently offered by the CERTCC-KR. 49 The initiatives include • providing free anti-virus software and vaccine programs to elementary and secondary education organizations • operating a 24x7 phone number for anyone to call and report computer security incidents and receive assistance in resolving them. This initiative is known as the Cyber 118 Operation. 47 48 49 For more information on US-CERT, see . The GRIP Working Group was disbanded when its work was completed. Its initial charter can be read at . For more information on CERTCC-KR, see . 34 CMU/SEI-2003-TR-001
• providing a test lab for information security products. This lab is available for free to industry. These initiatives show the diversity of CSIRT services. 2.3.9 Today’s Activities Today there are many more CSIRTs in operation and many different projects underway to facilitate coordination and information sharing between teams and to standardize terminology and processes in CSIRT operations. Some of the issues being discussed at the time of the publishing of this report in 2003 still reflect the original goals and objectives of early discussions, namely, to create an effective way to coordinate information sharing, analysis, and response between teams. Teams today are still investigating the tools required for this type of coordination and also what organizational structures will work best. Many areas are talking about creating regional coordination mechanisms to focus on particular geographic areas. How these regional mechanisms will then coordinate has yet to be determined. Other areas of discussion and activity include finding ways to standardize work and information exchange between CSIRTs, the impact of changing laws and regulations on CSIRT activities and organizational protection strategies, and the difficulty in finding, training, and retaining qualified incident handling staff. These activities, as well as information about how CSIRTs are currently operating, are discussed in the next section, “Current State of the Practice of CSIRTs.” CMU/SEI-2003-TR-001 35
