Input validation

Input validation in software development ensures an application’s security, reliability, and robustness. It involves checking and validating the data entered by users or received from external sources to ensure it meets specific criteria before processing. Proper input validation helps prevent security vulnerabilities, data corruption, and other malformed or malicious input issues.

Here are some critical considerations for implementing input validation in software:

  • Data type validation - Ensure that the input data is of the expected data type (for example, string, integer, date) before processing it. This helps prevent errors and vulnerabilities related to incorrect data types.
  • Length and size checks - Validate the length and size of input data to ensure it falls within acceptable limits. This prevents buffer overflows, memory issues, and other related vulnerabilities.
  • Format validation - Check if the input data matches the expected format...
