Data mining is used to reveal hidden relationships, patterns and trends by running queries on large data stores.
Data mining is the act of collecting and analyzing large quantities of information to determine patterns of use or behavior and use those patterns to form conclusions about past, current, or future behavior. Data mining is typically used by large organizations with large databases of customer or consumer behavior. Retail and credit companies will use data mining to identify buying patterns or trends in geographies, age groups, products, or services. Data mining is essentially the statistical analysis of general information in the absence of specific data.
The following are incorrect answers:
They are incorrect as they all apply to Protecting Objects and the data within them. Layering, abstraction and data hiding are related concepts that can work together to produce modular software that implements an organizations security policies and is more reliable in operation.
Layering is incorrect. Layering assigns specific functions to each layer and communication between layers is only possible through well-defined interfaces. This helps preclude tampering in violation of security policy. In computer programming, layering is the organization of programming into separate functional components that interact in some sequential and hierarchical way, with each layer usually having an interface only to the layer above it and the layer below it.
Abstraction is incorrect. Abstraction “hides” the particulars of how an object functions or stores information and requires the object to be manipulated through well-defined interfaces that can be designed to enforce security policy. Abstraction involves the removal of characteristics from an entity in order to easily represent its essential properties.
Data hiding is incorrect. Data hiding conceals the details of information storage and manipulation within an object by only exposing well defined interfaces to the information rather than the information itslef. For example, the details of how passwords are stored could be hidden inside a password object with exposed interfaces such as check_password, set_password, etc. When a password needs to be verified, the test password is passed to the check_password method and a boolean (true/false) result is returned to indicate if the password is correct without revealing any details of how/where the real passwords are stored. Data hiding maintains activities at different security levels to separate these levels from each other.
