Uploading and downloading files securely is essential for businesses.
When sharing large amounts of data, it’s crucial that your file-sharing system is able to defend itself against malicious attacks. Malware is often disguised as a harmless file with a benign extension like.jpeg,.gif or.bmp. This technique allows attackers to bypass security barriers and replace legitimate files with one that appears identical outwardly but has hidden malicious code inside. A good way to protect against these types of “undercover attacks” is to have an option to verify the contents of uploaded files based on their extensions.
You can set up your upload system so that it examines the name of the file type and/or extensions to determine whether they match with a known dangerous extension. This should be done in conjunction with a range of other security measures. A defense-in-depth approach is necessary to protect your service.
In addition to checking file names and extensions, your uploader should also examine the content of the files that are being uploaded. This will stop fraudulent or fake documents from being uploaded and shared. This is particularly important for sensitive files which may contain copyrighted or personal data.
Mitchell, for example seeks feedback from his team members about his marketing campaign. He uploads his campaign’s documents to SimplePractice and shares a link with his business partners. They can access the documents on their tablets, laptops and phones. They can also edit the document, and see changes in real time.
