The documentation of a predetermined set of instructions or procedures that describe how an organization’s mission/business processes will be sustained during and after a significant disruption.
Business Impact Analysis (BIA)
An analysis of an information system’s requirements, functions, and interdependencies used to characterize system contingency requirements and priorities in the event of a significant disruption. NIST SP 800-34 Rev. 1
Disaster Recovery (DR)
In information systems terms, the activities necessary to restore IT and communications services to an organization during and after an outage, disruption or disturbance of any kind or scale.
Disaster Recovery Plan (DRP)

Incident Handling, Incident Response (IR)
The mitigation of violations of security policies and recommended practices. Source: NIST SP 800-61 Rev 2
Incident Response Plan (IRP)
The documentation of a predetermined set of instructions or procedures to detect, respond to and limit consequences of a malicious cyberattack against an organization’s information systems(s). Source: NIST SP 800-34 Rev 1
Intrusion
A security event, or combination of security events, that constitutes a security incident in which an intruder gains, or attempts to gain, access to a system or system resource without authorization. Source: IETF RFC 4949 Ver 2
Security Operations Center
A centralized organizational function fulfilled by an information security team that monitors, detects and analyzes events on the network or system to prevent and resolve issues before they result in business disruptions.
Vulnerability
Weakness in an information system, system security procedures, internal controls or implementation that could be exploited or triggered by a threat source. Source: NIST SP 800-128.
