Validation

Validation is a process used in computing and cybersecurity to verify the accuracy of data. It is used to ensure that the data, information, or program meets certain requirements or constraints, such as correctness, consistency, completeness, reliability, and usability.

Validation functions similarly to verification, which is the process of confirming whether something is true or not. While verification helps to ensure that the data is correct, validation helps to ensure that the data fits the intended purpose, is valid, and complies with any security conditions set out for the data or program.

Validation is used in a variety of applications, from software and web development to cybersecurity, and can be done either manually or automatically. Manual validation checks are done by people, such as software developers and security professionals, while automated validation is done using various tools and algorithms. Automated validation can help to speed up the process and reduce potential human errors.

Validation is an essential part of almost any computer system or program and is a key part of the development process. It is used to ensure the accuracy and reliability of data, which is necessary for the proper functioning of the system or program. As such, it is important that validation be performed regularly and rigorously, as it can help to protect against data corruption and malicious attack.
