Securely uploading and downloading of business files is a crucial component of many online applications and services, such as content management systems and insurance websites, healthcare portals and messaging applications. Unrestricted uploads of data are the most common attack vector used by malicious actors to inject malware and take data.
A reliable file-uploading system must confirm that the uploaded files are compliant with a list of permitted file types, and also scan them for viruses prior storage. This ensures that private information of customers isn’t exposed, and adheres with compliance standards like HIPAA (for health-related information) and GDPR (for EU citizens).
It is essential to be able and able to confirm the file types, as attackers are able “mask” malicious software by changing the names of files to acceptable extensions like.jpg or.gif. Your solution may not be able to identify the actual file type, and it would let it go unnoticed. It is essential to use a file-uploading program which also checks the extension of the file to avoid this.
A strong encryption of all data both in flight and at rest is a way to protect yourself against various attacks. This converts messages and files into unreadable codes that can’t be read by hackers even when they gain access to the data.
You can also create an uploading process that rejects any files that don’t conform to your namestamps. This will help you keep your team organised and stop confidential information from being exposed in name of the file.
