Use FTP Network Security to configure login security parameters and protect your FTP server from network-based attacks. This feature enables you to deny access to an IP address based on a specified number of failed login attempts. However, you can, if desired, configure your site to log the failed login attempts without denying access.
The following tables describe the UI elements that are available on the feature page and in the Actions pane.
Deny IP addresses based on the number of failed login attempts
Restricts clients from access the FTP server after a specified number of failed login attempts.
Maximum number of failed login attempts
Sets the maximum failed login attempts after which the client is denied access. The default is 4 attempts.
Time period (in seconds)
Sets the number of seconds to wait before returning from a failed login attempt. The default is 30 seconds.
Write to the log only
Logs the failed attempts but allows access to the FTP server. This setting will not restrict clients even if the maximum failed attempts are exceeded.
