Securely uploading and downloading company files is a crucial component of many online applications and services, including content management systems, insurance websites, healthcare portals and messaging applications. The freedom to upload files is the most common attack vector for malicious actors who can easily insert malware and steal private data.
A reputable file upload system must verify uploaded files against a set of permitted file types and screen them for viruses before they are stored. This ensures that customers’ personal information isn’t disclosed and is in compliance with standards such as the HIPAA for health-related data as well as the GDPR for EU citizens.
The ability of confirming file types is essential as hackers often “mask” malicious files by renaming them to allowable extensions such as.jpg or.gif. Your solution might not be capable of detecting the actual file type, and thus allow it to pass unnoticed. To avoid this from happening, you require an uploader that can verify the extension of the file as well.
A strong encryption of all data both in flight helpful hints and at rest is another method to defend yourself against a variety of attacks. This converts messages and files into unreadable codes that can’t be read by hackers, even when they gain access to them.
Additionally you can also create an upload system which rejects files that don’t conform to your namestamps. This will help keep your team organized and prevents the disclosure of confidential information in the file names.
