Subject: Re: Reasons why BIND isn't being upgraded
I always thought that it was regarded as generally good security practice to give out as little information about your systems as possible, and none at all if you can help it. The BIND version should at least only be accessible from a set of defined IP addresses, defaulting to 127/8.
Not necessarily. As Paul has shown, and as I and others have explained in other forums, hiding the version identifier in this case can obscure the presense of an older buggy version that's in desparate need of upgrading. Only the most simplistic and poorly designed exploits would trust the version identifier anyway, *especially* after these kinds of discussions! ;-) Never try to hide something that's plainly obvious on some other level. It only makes people more curious, and I'm including those wearing grey and black hats in "people" here..... -- Greg A.
