Introduction to Cyber Security

The ability and means to communicate with or otherwise interact with a system, to use system resources to handle information, to gain knowledge of the information the system contains, or to control system components and functions.

An actual assault perpetrated by an intentional threat source that attempts to alter a system, its resources, its data, or its operations.

A list of entities that are blocked or denied privileges or access.

A computer connected to the Internet that has been surreptitiously/secretly compromised with malicious logic to perform activities under the remote command and control of a remote administrator.

A model for enabling on-demand network access to a shared pool of configurable computing capabilities or resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

The systems and assets, whether physical or virtual, so vital to society that the incapacity or destruction of such may have a debilitating impact on the security, economy, public health or safety, environment, or any combination of these matters.

The use of mathematical techniques to provide security services, such as confidentiality, data integrity, entity authentication, and data origin authentication.

The interdependent network of information technology infrastructures that includes the Internet, telecommunications networks, computer systems, and embedded processors and controllers.

The unauthorized movement or disclosure of sensitive information to a party, usually outside the organization, that is not authorized to have or see the information.

The processes and specialized techniques for gathering, retaining, and analyzing system-related data (digital evidence) for investigative purposes.

A comprehensive approach to risk management that engages people, processes, and systems across an organization to improve the quality of decision making for managing risks that may hinder an organization's ability to achieve its objectives.

The measures that protect and defend information and information systems by ensuring their availability, integrity, and confidentiality.

The process and methods for analyzing information from networks and information systems to determine if a security breach or security violation has occurred.

The numerical value used to control cryptographic operations, such as decryption, encryption, signature generation, or signature verification.

Software that compromises the operation of a system by performing an unauthorized function or process.

An actual assault perpetrated by an intentional threat source that attempts to learn or make use of information from a system but does not attempt to alter the system, its resources, its data, or its operations.

An evaluation methodology whereby assessors search for vulnerabilities and attempt to circumvent the security features of a network and/or information system.

A digital form of social engineering to deceive individuals into providing sensitive information.

A set of software tools with administrator-level access privileges installed on an information system and designed to hide the presence of the tools, maintain the access privileges, and conceal the activities conducted by the tools.

The level of confidence that software is free from vulnerabilities, either intentionally designed into the software or accidentally inserted at any time during its lifecycle, and that the software functions in the intended manner.

A computer program that can replicate itself, infect a computer without permission or knowledge of the user, and then spread or propagate to another computer.

A list of entities that are considered trustworthy and are granted access or privileges.
