At your RD Host, you would need to use a firewall rule. Secure firewall rules allow to use kerberos domain authentication, that is easier than certificates. Is the client that you use a domain joined machine?

1)I have a rdweb service that is  published over the interent I want to secure the authentication with client certificate so the user can't access without it.

You'll use a standard SSL cert for this. https://LetsEncrypt.org has provided these free for years now.

2) so how I can do it ?

This Microsoft Forum Article goes through the steps.

3) can I make it on usb flashdisk and secure it ?

No. SSL certs peg to an IP, not a USB device.

4) The above is the normal approach to securing rdweb. Where anyone can access your rdweb instance + they'll require login credentials to use the service. In other words, users will require a user/pass for the destination they're trying to reach using your rdweb instance.

If you must block who can even access your rdweb instance, then one of these will work.

a) Use firewall rules to only allow access to your rdweb instance from certain IPs.

b) Front end your rdweb instance with some sort of login screen, either Webserver or PHP based... or however you normally write code.

Likely all of #4 is overkill as a person will require a valid user/pass to access any endpoint, so the user/pass requirement is likely sufficient.

Unfortunately, David, using a certificate that way does not do what the question is targeted at: it does not ensure that the user can't access the server without it. Using the certificate that way merely encrypts the connection and tells the client that the server is indeed the expected server.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

I mean a client certificate not a server certificate like the banks usb token.
thanks.

That was already understood and that is what I replied to: you may use certificates within secure firewall rules, but it is easier to do it with kerberos domain authentication. That's why I asked you, whether the client is joined to the same domain as the target server. Is it?

@McKnife - Item #4 in my list answers original question. I listed this answer last as likely this is overkill.

Well, the question was, how to do it by means of a certificate and 4) does not use certificates.
[Please note, that I have asked the author, whether he would possibly rather use domain kerberos authentication than certificates]

Hello,
in pki in general  and under iis website there is an option client certificate required.
so the client will authenticate through the rdweb and the client certificate.
thanks.

So you found a way through IIS? Good, then please indicate that and close the question by selecting your own comment as solution.
