Secure Upload Guide

Ensuring the security of file uploads is crucial for maintaining the integrity and privacy of your website. This guide will walk you through the best practices for implementing secure file uploads.

Best Practices

Validate File Types: Always validate the file type before processing the upload. This helps prevent malicious files from being uploaded.
Use Secure Connections: Make sure your website uses HTTPS to encrypt data in transit.
Store Files Securely: Store uploaded files in a secure location with restricted access.
Limit File Sizes: Set a maximum file size limit to prevent denial-of-service attacks.
Use Secure Permissions: Set the correct file permissions to prevent unauthorized access.

Example

Here's an example of a file upload form:

<form action="/upload" method="post" enctype="multipart/form-data">
  <label for="file">Select file:</label>
  <input type="file" id="file" name="file">
  <input type="submit" value="Upload">
</form>
