- Validation The process of verifying that data or information meets certain criteria or standards. It is used to ensure the accuracy and consistency of data and to prevent errors or inconsistencies. Examples include verifying the format of a phone number or email address or checking that a password meets the required complexity criteria.
- 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.
- Variable samplingA statistical analysis method where a subset of data from a larger population is examined to draw conclusions about the larger set. In the context of system auditing and security, variable sampling might be used to analyze patterns of behavior, detect anomalies, and identify potential threats or vulnerabilities. The goal is to uncover insights that can help improve system security without the need to analyze every single piece of data.
- 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.
- Vendor Lock-in (Cloud Computing)A situation where a customer using cloud services becomes dependent on a single cloud provider's infrastructure and tools, making it difficult or costly to migrate to another service. This can be due to proprietary technologies, custom APIs, or data transfer costs.
- Vendor Lock-out (Cloud Computing)A strategy where a cloud service provider may exclude competitors' services or products from integrating with its own platform, enforcing a form of ecosystem control that can limit customer choice and interoperability between different cloud services.
- 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.
- Very Early Smoke Detection Apparatus (VESDA)A system that actively draws air through a network of pipes to a central detector, enabling it to provide a very early warning of potential fire situations. It detects minute smoke particles in the air, thus allowing organizations to initiate response procedures before any visible signs of fire appear, minimizing potential damage and enhancing safety.
- 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.
