Safe uploading and downloading business files is a key component of a variety of online applications and services, including content management systems as well as insurance portals, healthcare portals and messaging apps. Making uploads open to all is the most common attack vector for malicious actors who could easily install malware and steal private information.
A reliable system for uploading files should verify that uploaded files are in compliance with a list of acceptable file types, and also scan them for viruses prior to storing. This helps ensure that clients’ personal information isn’t disclosed and is in compliance with requirements such as HIPAA for health-related data as well as the GDPR for EU citizens.
It is essential to be able to identify the types of files, as hackers are able to “mask” malicious programs by renaming the files to acceptable extensions like.jpg or.gif. This means that your solution might not be able of identifying the file’s actual type and could allow it to pass without being detected. You will require a file-uploading system that also validates the extension of the file to prevent this.
Another way to safeguard yourself against a variety of threats is to apply a strong encryption to all data during travel and at rest. This converts messages and files into codes that are unreadable, and can’t be read by hackers, even in the event that they gain access to them.
Additionally, you can set up an upload system for files which will reject files that do not conform to your naming conventions. This helps you organize your team and also prevents you from exposing confidential information in the names of files.
