Availability Assures information is available when needed
Awareness Security Control designed to change user behavior
Background checks A Verification of a person's background and experience, Also called pre-
employment screening
Baseline Uniform ways to implement a safeguard , administrative control
,Baseline The minimum level of security necessary to support and enforce a security policy.
Best evidence rule Requires use of the strongest possible evidence
Best practice A consensus of the best way to protect the confidentiality, integrity and
availability of assets
Bot A computer system running malware that is controlled via a botnet
Botnet A central bot command and control (C&C) network, managed by humans
Breach notification Notification of persons whose personal data has been, or is likely to have been,
compromised
Business Impact Analysis (BIA) A functional analysis in which a team collects data, documents business functions,

even other evidence
Civil law Law that resolves disputes between individuals or organizations
Civil law (legal system) Legal system that leverages codified laws or statues to determine what is
considered within the bounds of law
Classification A systematic arrangement of objects into groups or categories according to a set
of established criteria. Data and resources can be assigned a level of sensitivity as
they are being created, amended, enhanced, stored, or transmitted. The
classification level then determines the extent to which the resource needs to be
controlled and secured, and is indicative of its value in terms of information
assets.
Collection Limitation Principle OECD Privacy Guideline principle which states personal data collection should
have limits, be obtained in a lawful manner, and, unless there is a compelling

Corroborative evidence Evidence that provides additional support for a fact that might have been called
into question
cost/benefit analysis An assessment that is performed to ensure that the cost of a safeguard does not
outweighs the benefit of the safeguard. Spending more to protect an asset than
the asset is actually worth does not make good business sense. All possible
safeguards must be evaluated to ensure that the most security-effective and cost-
effective choice is made.
countermeasure A control, method, technique, or procedure that is put into place to prevent a
threat agent from exploiting a vulnerability. A countermeasure is put into place to
mitigate risk. Also called a safeguard or control
Cracker A black hat hacker
