Securely uploading and downloading company files is an important element of a variety of online applications and services, such as content management systems such as healthcare portals, insurance sites and messaging apps. Making uploads open to all is an ideal attack point for malicious actors who could easily inject malware and steal private information.

A reputable file upload system should verify uploaded files against a list that allows types of files and examine them for viruses prior to they are stored. This ensures that customers’ personal information is not compromised and it complies with compliance standards like the HIPAA for health-related records and GDPR for EU citizens.

The ability to identify the file type is vital as attackers are able to “mask” malicious files by renaming them to allowable extensions such as.jpg or.gif. This means that your solution might not be able of identifying the actual file type, and will allow it to go without being detected. To avoid this, you need a system for uploading files that verifies the file extension as well.

Another way to protect against various attacks is to apply a strong encryption to all information during both in flight and at rest. This converts messages and files into unreadable codes that can’t be read by hackers even when they gain access to them.

In addition, you can create an uploading system for your files which will reject files that don’t conform to your naming conventions. This will help you organize your team and also prevent confidential information from being exposed in file names.
