Define maximum file size
Summary
The files manipulated by the system and the users must have a defined maximum file size (5MB recommended).
Description
When a system allows users to upload or attach files for storage, the maximum file size limit must be defined for these files, in order to avoid issues involving the availability of the service and to reduce the chance of an attacker uploading a file containing malicious software.
