Info

Nebraska Information Technology Commission The Nebraska Information Technology Commission (NITC) has developed a set of procedures for reporting security breaches involving Nebraska state agencies. We have reproduced the procedures document in this appendix. These incident response procedures also include both a short and long form for reporting incidents: • Computer Incident Reporting Short Form • State of Nebraska Information Systems Administrator’s Incident Reporting Form The document and forms are available from http://www.nitc.state.ne.us/standards/ (see the links for the “Security Architecture” section) [Nebraska 02]. 2086 CMU/SEI-2003-TR-001
Nebraska Information Technology Commission Standards and Guidelines Security Architecture Title Category Incident Response and Reporting Procedure for State Government Security Architecture Date Adopted June 18, 2002 Date of Last Revision April 5, 2002 Date of Next Review June 2004 State Agencies shall prepare procedures for reporting security breaches and incidents. Documentation on security incidents shall be filed with the Chief Information Officer for the State of Nebraska. Explanation / Key Points Security is a growing problem. Effective response and collective action are required to counteract security violations and activities that lead to security breaches. Agency management, law enforcement, and others must know the extent of security problems in order to make proper decisions pertaining to policies, programs and allocation of resources. Responding to security alerts will help to prevent incidents from occurring. Quick reporting of some incidents, such as new viruses, is essential to stopping them from spreading and impacting other systems. Reporting computer crimes is the only way for law enforcement to deter and apprehend violators. These guidelines incorporate most of the “CIO Cyberthreat Response and Reporting Guidelines” jointly sanctioned by the FBI and U.S. Secret Service. A copy of those guidelines is available at: http://www.cio.com/research/security/incident_response.pdf, http://www.usss.treas.gov/net_intrusion.shtml, or http://www.fbi.gov/pressrel/pressrel02/cyberguidelines.htm. Effective response to security incidents requires quick recognition of problems and fast mobilization of skilled staff to return systems to normal. This requires prior documentation of procedures and responsibilities of everyone with a role in responding to the emergency. Continuous improvement by eliminating points of vulnerability and applying lessons learned is an essential component of incident response. Centralized reporting serves the goal of increasing awareness of vulnerabilities and threats to state government as a whole. In particular, centralized reporting is necessary to discern patterns, identify areas of vulnerability, allocate resources, and develop statewide solutions. Centralized reporting does not substitute for internal reporting to management, reporting to law enforcement, or mobilizing a computer security incident response team (CSiRT). Agencies should develop procedures for internal and external
