CPM Dictionary: V
Vaccination: Procedures for immunization against an infectious disease
Vaccine: Substance used for active immunization by introducing into the body a live modified, attenuated, or killed inactivated infectious organisms or its toxin; designed to stimulate the body’s immune response resulting in resistance to the infection
Variant: Modified virus version; produced on purpose by virus author or another person amending the virus code
Vector: Insect or any other living carrier that transports an infectious agent from an infected individual or its wastes to a susceptible individual or its food or immediate surroundings
Vendor-Managed Inventory (VMI) Package: See National Pharmaceutical Stockpile Program
Verification: Process of comparing two levels of system specification for proper correspondence, such as security policy model with top-level specifications, top-level specs with source code, or source code with object code
Victim: Person who has been affected by a disaster; three classes: a) primary victims – affected by physical impact of a disaster; b) secondary victims – reside within an affected community or on the border of an affected area and suffer economic loss due to the disaster or actions taken by relief operations; and c) tertiary victims – those who are indirectly affected. See also Victim Distribution
Victim Distribution: Process of defining the method of transportation and distribution of victims among neighboring hospitals according to their hospital treatment capacity. See also Victim
Viral: Having the features of a virus, particularly self-reproduction
Viral Agents: Group of viruses that have been selected as biological warfare agents because of their ability to produce disease, illness, and death in susceptible individuals. See also Biological Warfare Agent
Virtual Private Network (VPN): Restricted-use, logical computer network that is built from system resources of a public, physical network (the Internet), often by using encryption (located at hosts or gateways), and often by tunneling links of the virtual network across the real network; generally less expensive to build and operate than a dedicated real network, because the virtual network shares the cost of system resources with other users of the real network
Virus: Unauthorized program that inserts itself into a computer system and then propagates itself to other computers via networks or disks; can interfere with computer system operation; cannot run by itself and requires running the host program to activate the virus
Virus Definitions File: Provides information to antivirus software to find and repair viruses
Vital Record: Must be preserved and available for retrieval if needed
Vital Record Location: Facility for storing vital records; usually highly secure and physically distant from the primary operations site. See also Offsite Location, Records
VMI Packages: See National Pharmaceutical Stockpile Program
Voice Recovery: Replacement and reactivation of voice communications services at another site; an important application is recovery of call centers
Volcano: Eruption from the earth's interior producing lava flows or violent explosions issuing rock, gasses, and debris
Voluntary Agency (VOLAG): Non-profit, non-governmental, private association maintained and supported by voluntary contributions that provides assistance in emergencies and disasters
VOLAG: See Voluntary Agency
Voluntary Evacuation: Warning to persons within a designated area that a threat to life and property exists or is likely to exist in the immediate future; when this type of warning is issued residents are NOT required to evacuate, however it would be in their best interests to do so (FEMA). See also Evacuation
Vulnerability: 1) Flaw or weakness in a system design, implementation, or operation and management that could be exploited to violate the system's security policies; lets attackers execute commands as another user; helps attackers access data that is contrary to the specified access restrictions for that data; lets attackers pose as another entity, or helps an attacker conduct a denial of service attack; 2) mathematical function defined as the degree of loss to a given element at risk, or set of such elements, expected to result from the impact of a disaster hazard of a given magnitude; 3) incorporates considerations of both the intrinsic value of the elements concerned and their functional value in contributing to communal well-being in general and to emergency response and post-disaster recovery in particular. See also Hazard; Vulnerability
Vulnerability Analysis: 1) Systematic examination of systems to determine adequacy of security measures, identify security deficiencies, and provide data to predict effectiveness of proposed security measures; 2) analysis of theoretical and empirical data concerning the effects of particular phenomena on particular types of structures; 3) consideration of all significant elements in society, including physical, social and economic considerations (both short- and long-term), and the extent to which essential services (and traditional and local coping mechanisms) are able to continue functioning
Vulnerability Assessment: Measurement of vulnerability that includes susceptibility of a particular system to a specific attack and opportunities available to a threat agent to mount such an attack
Vulnerability, Disaster: See Disaster Vulnerability
Vulnerability Management: Identifying and removing weaknesses that can be used to compromise the confidentiality, integrity, or availability of a computer information asset; preventive information security practice that identifies and removes weaknesses before they can be used to compromise a computer information asset
Vulnerability Measure: Quantitative measurement of vulnerability, using such factors as physical exposure, electronic exposure, potential damage, age, and information
Vulnerability Measure Factors: Elements used to calculate the danger posed by vulnerabilities (vulnerability measure); rated in terms of physical exposure, electronic exposure, potential damage, information, and age
Vulnerability Safeguard: Process, procedure, technique, or feature that assists in securing a vulnerability by reducing risks linked to the system's vulnerability measure
Vulnerable Groups: Categories of displaced persons with special needs, including unaccompanied minors, elderly, mentally and physically disabled, victims of physical abuse or violence and pregnant, lactating or single women
VX: Refers to "Virus eXchange" community, those who consider it right and proper to write, share, and release viral programs, including those with damaging payloads
