Compare file format and extension
Summary
The system must validate that the format (structure) of the files corresponds to their extension.
Description
This is a security measure that can be useful for validating the integrity and authenticity of files in a system or application. This process involves verifying that the actual content or format of a file matches the file extension it claims to have. Mismatches between file formats and extensions can indicate potential security risks or attempted attacks.
