If it’s sharing medical records with clients or sharing project data to remote collaborators, safe uploading and downloading business files are crucial for the productivity of users. These essential business processes are susceptible to data breaches and attacks when they aren’t properly secured.
Implementing verification of file uploads on your website is the best way to keep from such threats. This involves identifying potentially harmful content in a users files and verifying that they have the extension they claim to have.
In practice, this means you must ensure that your portal is checking for malicious extensions to files like.exe,.dll and.bat. You should also ensure that your files are encrypted to keep sensitive information from being stolen and exposed online. This also includes allowing users to only upload recognizable, valid file types (like jpg or png) and removing potentially hazardous patterns and characters from file names in order to prevent hackers from hiding malicious content in innocent-sounding file formats.
Another important aspect is to ensure that you’re not exposing sensitive data on your server in the first place. You can accomplish this by making sure that users sign in with their passwords before they are able to access uploaded files. Furthermore, you should encrypt the pass token provided by the uploading source and transmit it to your own server so that your users only access the corresponding data on your system.
It’s also important to keep in mind that even it’s an encrypted portal and your files are encrypted however, it’s a good idea to never share copies of your material on a public site. This could result in legal issues and harm your company’s reputation. Use secure methods of communication like email or facsimile, as well as meetings with colleagues to meet your company’s requirements.
