How do I hide SQL Server version information?

I don't know exactly what the combination of nmap and SQL Server is, but it's general.

There are several ways the scanning tool can identify the server version.

Most settings can be hidden in 1.2. There are times when the interpretation of may need to be changed depending on the version, and there are many things that cannot be hidden or that cannot be hidden.3. There's nothing I can do about it.

The bottom line is that it should not be hidden by settings.

If the configuration looks like a person who is having trouble seeing the version information, it's a problem in itself

No, it's not.The version information is not inherently relevant to whether the system is safe from attacks.

The bad one is 3.4.

A decade ago, when there were no sufficient authentication mechanisms or data protection, DB was absolutely something to hide, but nowadays TLS encryption and authentication are possible, and both the idea itself and the internal network are shifting to unreliable assumptions.

Ideally, whether external or internal, it should be secure and the version information is visible and invisible (both visible and unconnected and unconnected) is essentially irrelevant.
