Validity check: A process that verifies if data entered into a system adheres to specified rules and formats. These checks are typically performed to maintain data integrity and reduce the likelihood of errors or inconsistencies. For example, a validity check might ensure that an email address entered into a system is in the correct format.

Variant: A version or form of something that is slightly different from the original. In the context of malware, for instance, a variant refers to a version of the malicious software that has been slightly altered from its original form, often to avoid detection by security measures or to adapt to different environments.

Verification: The process of ensuring that a product, system, or component meets specified requirements. It involves a series of checks and balances to ensure that what was designed, created, or implemented aligns with the original intentions or goals. Verification is often used to ensure that security measures are properly in place and functioning as intended.

Video and audio recording tools: The technology used to capture, store, and playback visual and auditory data. In the context of maintaining organizational security, such tools can be used for monitoring environments for any suspicious activities, recording incidents for investigation or evidence purposes, and training personnel on security protocols.

Video monitoring or video surveillance: The use of cameras and other visual recording devices to monitor and record activities within a specific area. It is used for security purposes, to identify potential threats or incidents, and to provide evidence of criminal activity. Examples include CCTV cameras in a shopping mall or security cameras in a parking lot.

Virtual circuits: A connection-oriented communication model that allows data to be delivered between two network nodes. They create a logical path between source and destination, mimicking the behavior of a physical circuit but over a shared network infrastructure, providing a degree of isolation and security between communication sessions.
