Well, no. I don't know that the only way to protect a port/service is knowing its existence. I suspect that many hackers try brute force methods to find ports instead of a using a port scanner. How does knowing a port/service protect it? I thought the idea was you find the port/services you use then you allow them. Obscurity is a common way of protecting data. A password is a form of obscurity isn't it? I recall a telecommunication technician working on our network. He connected a device which showed him some passwords (we no longer use that communication method). I guess, someone with a port scanner is more dangerous than someone who doesn't have one. Better tools will result in better results regardless of intent. <[log in to unmask]> wrote in message news:a3qrdt02g1j@enews4.newsguy.com... > Protection through obscurity? > Haven't you heard about port scanners? > > Don't you know the only mean to protect a port/service is knowing its > existence? > > Regards, > > -- Andres j.
