What is anonymous FTP?

Anonymous FTP allows users to connect to an FTP server without a personal account, using the username anonymous and any string (typically an email address) as the password. It was historically used to distribute public software but is now considered a security risk on servers that host sensitive data.

Why check for anonymous access?

  • Unintended anonymous access can expose private files to the public internet.
  • Attackers use anonymous FTP to upload malware or use the server as a staging point.
  • Many compliance frameworks (PCI-DSS, HIPAA) require anonymous FTP to be disabled.
