Securely uploading and downloading company files is an essential component of numerous online applications and services, such as content management systems, insurance portals, healthcare portals and messaging apps. Unrestricted uploads of files are the most common attack channel used by malicious hackers to insert malware and steal data.

A reputable system for uploading files will check uploaded files against a list of allowed types of file and screen them for viruses before they are saved. This ensures that personal data of the users are not disclosed, and it complies with compliance standards like HIPAA (for health-related information) and GDPR (for EU citizens).

It is vital to be able verify the file type, since hackers are able to “mask” malicious software by changing the names of files to acceptable extensions like.jpg or.gif. Your solution might not be capable of detecting the actual file type, and thus allow it to be ignored. To avoid this, you’ll need an uploader system that can verify the extension of the file as well.

A strong encryption of all data both in the air and at rest is a way to defend yourself against a variety of attacks. This transforms messages and files into unreadable code that hackers cannot read even in the event that they gain access to.

You can also create a system for uploading files which rejects files that do not conform to your namestamps. This will help organize your team and avoids exposing confidential information in the names of files.
