In the fields of computer security and information technology, computer security incident management involves the monitoring and detection of security events on a computer or computer network, and the execution of proper responses to those events. Computer security incident management is a specialized form of incident management, the primary purpose of which is the development of a well understood and predictable response to damaging events and computer intrusions. 
Incident management requires a process and a response team which follows this process. This definition of computer security incident management follows the standards and definitions described in the National Incident Management System (NIMS). The incident coordinator manages the response to an emergency security incident. In a Natural Disaster or other event requiring response from Emergency services, the incident coordinator would act as a liaison to the emergency services incident manager. 
Computer security incident management is an administrative function of managing and protecting computer assets, networks and information systems. These systems continue to become more critical to the personal and economic welfare of our society. Organizations (public and private sector groups, associations and enterprises) must understand their responsibilities to the public good and to the welfare of their memberships and stakeholders. This responsibility extends to having a management program for “what to do, when things go wrong.” Incident management is a program which defines and implements a process that an organization may adopt to promote its own welfare and the security of the public.
An event is an observable change to the normal behavior of a system, environment, process, workflow or person (components). There are three basic types of events:
Computer security and information technology personnel must handle emergency events according to well-defined computer security incident response plan.
An incident is an event attributable to a human root cause. This distinction is particularly important when the event is the product of malicious intent to do harm. An important note: all incidents are events but many events are not incidents. A system or application failure due to age or defect may be an emergency event but a random flaw or failure is not an incident.
The security incident coordinator manages the response process and is responsible for assembling the team. The coordinator will ensure the team includes all the individuals necessary to properly assess the incident and make decisions regarding the proper course of action. The incident team meets regularly to review status reports and to authorize specific remedies. The team should utilize a pre-allocated physical and virtual meeting place. 
The investigation seeks to determine the circumstances of the incident. Every incident will warrant or require an investigation. However, investigation resources like forensic tools, dirty networks, quarantine networks and consultation with law enforcement may be useful for the effective and rapid resolution of an emergency incident.
Incident Response Steps
Computer security, cybersecurity, or information technology security is the protection of computer systems and networks from information disclosure, theft of, or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.
Emergency services and rescue services are organizations which ensure public safety and health by addressing different emergencies. Some of these agencies exist solely for addressing certain types of emergencies whilst others deal with ad hoc emergencies as part of their normal responsibilities. Many of these agencies engage in community awareness and prevention programs to help the public avoid, detect, and report emergencies effectively.
The Incident Command System (ICS) is a standardized approach to the command, control, and coordination of emergency response providing a common hierarchy within which responders from multiple agencies can be effective.
The United States Computer Emergency Readiness Team (US-CERT) is an organization within the Department of Homeland Security’s (DHS) Cybersecurity and Infrastructure Security Agency (CISA). Specifically, US-CERT is a branch of the Office of Cybersecurity and Communications' (CS&C) National Cybersecurity and Communications Integration Center (NCCIC).
Help desk and incident reporting auditing is an examination of the controls within the help desk operations. The audit process collects and evaluates evidence of an organization's help desk and incident reporting practices, and operations. The audit ensures that all problems reported by users have been adequately documented and that controls exist so that only authorized staff can archive the users’ entries. It also determine if there are sufficient controls to escalate issues according to priority.
A command center is any place that is used to provide centralized command for some purpose.
The New Zealand Co-ordinated Incident Management System (CIMS) is New Zealand's system for managing the response to an incident involving multiple responding agencies. Its developers based the system on California's Incident Command System (ICS) - developed in the 1970s - and on other countries' adaptations of ICS, such as Australia's Australasian Inter-Service Incident Management System (AIIMS).
An incident is an event that could lead to loss of, or disruption to, an organization's operations, services or functions. Incident management (IcM) is a term describing the activities of an organization to identify, analyze, and correct hazards to prevent a future re-occurrence. These incidents within a structured organization are normally dealt with by either an incident response team (IRT), an incident management team (IMT), or Incident Command System (ICS). Without effective incident management, an incident can disrupt business operations, information security, IT systems, employees, customers, or other vital business functions.
Critical infrastructure protection (CIP) is a concept that relates to the preparedness and response to serious incidents that involve the critical infrastructure of a region or nation.
Database security concerns the use of a broad range of information security controls to protect databases against compromises of their confidentiality, integrity and availability. It involves various types or categories of controls, such as technical, procedural/administrative and physical.
The Oklahoma Emergency Management Act of 2003 is an Oklahoma state law that replaced the Oklahoma Civil Defense and Emergency Resources Management Act of 1967 as the primary state law detailing emergency management in Oklahoma. The Emergency Management Act and the Catastrophic Health Emergency Powers Act together form the primary state laws regarding emergency and disastrous situations that may occur in the state.
Document Exploitation (DOCEX) is the set of procedures used by the United States Armed Forces to discover, categorize, and use documents seized in combat operations. In the course of performing its missions in the War on Terrorism, members of the United States Armed Forces discover vast amounts of documents in many formats and languages. When documents are suspected of containing information of potential intelligence value, rapid and accurate interpretation of the information identifies targets, bolsters success in subsequent operations, and enhances tactical and strategic all-source intelligence efforts. The sheer volume of documents acquired in the course of military operations can overwhelm a unit's capability to extract meaningful information in a timely manner.
Presidential Decision Directive 62 (PDD-62), titled Combating Terrorism, was a Presidential Decision Directive (PDD), signed on May 22, 1998 by President Bill Clinton. It identified the fight against terrorism a top national security priority.
The Emergency Data Exchange Language (EDXL) is a suite of XML-based messaging standards that facilitate emergency information sharing between government entities and the full range of emergency-related organizations. EDXL standardizes messaging formats for communications between these parties. EDXL was developed as a royalty-free standard by the OASIS International Open Standards Consortium.
Security information and event management (SIEM) is a field within the field of computer security, where software products and services combine security information management (SIM) and security event management (SEM). They provide real-time analysis of security alerts generated by applications and network hardware. Vendors sell SIEM as software, as appliances, or as managed services; these products are also used to log security data and generate reports for compliance purposes. The term and the initialism SIEM was coined by Mark Nicolett and Amrit Williams of Gartner in 2005.
An information security operations center is a facility where enterprise information systems are monitored, assessed, and defended.
IT risk management is the application of risk management methods to information technology in order to manage IT risk, i.e.:
Emergency Responder Health Monitoring and Surveillance (ERHMS) is a health monitoring and surveillance framework developed by a consortium of federal agencies, state health departments, and volunteer responder groups designed to address existing gaps in surveillance and health monitoring of emergency responders. The framework provides recommendations, guidelines, tools, and trainings to protect emergency responders during each phase of an emergency response, including pre-deployment, deployment, and post-deployment phases. ERHMS was designed to function within the Federal Emergency Management Agency's (FEMA's) National Incident Management System (NIMS), a systematic approach to emergency management. The ERHMS trainings satisfy Public Health Emergency Preparedness capability 14, "Responder Safety and Health."
Threat Intelligence Platform is an emerging technology discipline that helps organizations aggregate, correlate, and analyze threat data from multiple sources in real time to support defensive actions. TIPs have evolved to address the growing amount of data generated by a variety of internal and external resources and help security teams identify the threats that are relevant to their organization. By importing threat data from multiple sources and formats, correlating that data, and then exporting it into an organization’s existing security systems or ticketing systems, a TIP automates proactive threat management and mitigation. A true TIP differs from typical enterprise security products in that it is a system that can be programmed by outside developers, in particular, users of the platform. TIPs can also use APIs to gather data to generate configuration analysis, Whois information, reverse IP lookup, website content analysis, name servers, and SSL certificates.
