Secure uploading and downloading of business files

It’s essential that your file sharing system can protect you from malicious attacks when you share large quantities of data. Malware often takes the form of a malicious file with an unimportant extension, like.jpeg or.gif. This tactic allows attackers to bypass security barriers and replace a legitimate file with one that appears identical outwardly but has hidden malicious code within. An effective way to guard against these types of “undercover attacks” is to have an option that checks the content of uploaded files based on their extensions.

To accomplish this, you should set your upload system to check for the name of a file type and/or extension to determine whether it is compatible with a malicious or fake extension. This should be done in conjunction with a variety of other security measures. The use of a single method is not enough to protect your service, so a defense-in-depth approach is recommended.

In addition to checking file names and extensions, your uploader must also check the content of the files before they are being uploaded. This will keep fake or malicious documents from being uploaded and shared. This is particularly important for sensitive files which may include copyrighted or personal data.

For instance, Mitchell needs feedback from his business partners on a marketing campaign. Mitchell uploads the campaign’s files to SimplePractice and shares them with his partners via the link. They helpful hints can access documents on their laptops, tablets and phones. They can even edit the document and see changes in real time.
