Name servers software versions are exposed
Posted: Sat May 08, 2021 3:29 pm
Hello,
I was checking my domain with www.dnsinspect.com tool, and i receive a security alert that:
--------------------------------
Name Servers Versions
WARNING: Name servers software versions are exposed:
17x.xx.xx.xx: "9.11.5-P4-5.1+deb10u5-Debian"
Exposing name server's versions may be risky, when a new vulnerability is found your name servers may be automatically exploited by script kiddies until you patch the system
--------------------------------
I think it is important to hide that debian is running, and send me to : https://www.dnsinspect.com/articles/hide-version.html
But i dont know exactly which file to edit on Debian10 and which bind file is required to fix.
Any help with a short tutorial?
