Hi,

I have FTP server and I see that "bad guys" all the time trying to
break it with "Administrator" user.
What are recommended options to secure it (disable Administrator
account is not acceptable)?

Is there a way completely prevent for "Administrator" account to login
through FTP?
Or at least maybe there is any security policy that can configure a
kind of pause (15-20 min) between login failures retries?

Thanks,

Bernard,

I tried the vbs and this is exactly what I needed.

Many thanks,
Maxim.

I think the best is to rename the administrator account. of coz this won't
prevent the attack as the attackers will keep trying to send all sort of
usernames to gain access.

You can implement account locked out policy, but that may really cause the
real account being locked out.

if you know where the client connections, then you can use IP restriction to
block unknown addressess access. however if this is public then this option
is not feasible.

alternately you can try this. some folks wrote the scripts for auto banning
the bad ip address.
