WN25-00-000420 - Windows Server 2025 FTP servers must be configured to prevent anonymous logons.

Information

The FTP service allows remote users to access shared files and directories. Allowing anonymous FTP connections makes user auditing difficult.

Using accounts that have administrator privileges to log on to FTP risks that the userid and password will be captured on the network and give administrator access to an unauthorized user.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Configure the FTP service to prevent anonymous logons.

Open IIS Manager.

Select the server.

Double-click 'FTP Authentication'.

Select 'Anonymous Authentication'.

Select 'Disabled' under 'Actions'.
