Previous Question Next Question

To protect file uploads from malware, implement a combination of server-side validation, antivirus scanning, and content-type verification. This ensures that only safe and expected files are processed and stored.

Example Concept: When handling file uploads, it's crucial to validate the file type and size on the server-side, scan for malware using an antivirus solution, and verify the content type against expected MIME types. Additionally, store files outside the web root to prevent direct access.

Additional Comment:

Always validate file extensions and MIME types to ensure they match expected formats.
Use a reputable antivirus library or service to scan files immediately upon upload.
Implement size limits to prevent large, potentially harmful files from being uploaded.
