Uploading files is an essential feature of many services and applications. They’re used in many systems for managing content and insurance sites, healthcare portals and messaging applications. However, allowing uploads of files to malicious actors could expose your customers to security breaches involving their data.

In order to ensure secure uploading and downloading, a solution must be implemented which checks uploaded file’s contents against the whitelist of approved types of files and scans for viruses. This is especially important if you handle customer data and must be compliant with laws like HIPAA or GDPR for EU citizens.

A good file uploading system should also be able to secure data when it is in transit and while at rest. This stops the data from being readable by third parties. It also protects your business from expensive fines and lawsuits if are not compliant.

In addition you should ensure that you only store uploaded files in specific storage locations on your database, server or cloud storage service and return a hyperlink to the file to the user. This will decrease the likelihood that hackers can gain access to your server, and also steal sensitive information from customers.
