If it’s sharing medical records with clients, or sharing project data with remote collaborators, secure uploading and downloading of documents are vital to user productivity. However, without adequate security, these essential business processes can expose your organization to attacks and data security vulnerabilities.
Implementing validation of uploads into your portal is the best way to keep away threats like this. This involves identifying potentially harmful information within the files of a user and confirming that they match to the extension they claim to have.
In actual practice, this implies ensuring that your portal checks for harmful file extensions such as.exe,.dll, and.bat, as well as encrypting files to prevent sensitive information from being stolen and then exposed to the public internet. This also means allowing users to upload only recognizable, valid files (like jpg and png) and removing potentially harmful characters and patterns from file names to stop attackers from hiding malicious files behind innocent-sounding formats.
Another important element is to ensure that you’re not exposing sensitive information on your server in the first place. This can be accomplished by requiring users to input their password before they are able to access uploaded files. Also, you should secure the pass token provided by the upload source and send it to your own server so 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 portal however, it’s still recommended not to publish copyrighted content on a public website. This could lead to legal issues and damage your company’s reputation. Instead, you should use secure methods of exchange, such as email, fax, or meeting with colleagues in person to address your business requirements.
