It is essential that users upload and download files for business securely, whether sharing medical records with clients, or transferring data to distant collaborators. But without proper security, these critical business processes can expose your business to attacks and data breaches.
Implementing a validation process for uploads to files in your portal is a great way to ward from such threats. This involves identifying potentially risky contents in users’ files and then confirming they match the extension they claim they have.
In practice, this means that you should ensure that your portal checks for dangerous file extensions such as.exe,.dll, and.bat, as well as encrypting files to keep sensitive data from being stolen and then exposed on the web. This also means allowing users upload only recognizable, valid files (like png and jpg) and removing potentially harmful characters and patterns from the file names to stop attackers from hiding malicious contents behind innocent-sounding formats.
Another important thing to consider is to ensure that your server doesn’t contain any sensitive information. You can do this by making sure that users sign in with their passwords before they are able to access uploaded files. In addition, you must encrypt the pass code supplied by the upload source and then send it to your own server in order that your users are able to access the corresponding data on your system.
It’s important to remember that even when your files are encrypted and you’re using an encrypted platform however, it’s still recommended not to share copyrighted information on a website that is public. This could result in legal issues and can cause a sense of suspicion in your company’s image. Use secure methods of communication, like email, facsimile, or meetings with colleagues to meet your company’s requirements.
