I'm not worried about myself. In a regulated environment the agencies do not trust corporations will honestly test their controls, so they have outside auditing firms and agencies test them for you and it is often these outside firms or agencies that take unreasonable or uneducated stances and often times there is very little you can do.

That's just me though. > Fortunately I don't really use Samba. I agree whole heartily. It would go a long way though if Redhat provided independent certification of their products under these compliance banners. Does anybody know if such a thing exists now? That way with the certification in hand and proof that the servers are kept up to date one can keep the auditors at bay. > > I think it will be these compliance issues that may force > > upstream to change their strategy otherwise I can see this > > being a roadblock to RHEL/CentOS adoption in these > > industries in the future. > > I highly doubt it.

You know that is if the auditing firms and agencies actually use scanning software, or if they ask for a package listing and go through that list by hand.

One can only hope that with a certificate from Redhat that they keep software up to date with security fixes within a reasonable time frame by backporting them can be had. Then there is the whole convincing these firms and agencies that since CentOS is a duplication of Redhat's system it is therefore certified by the laws of transitivity, but who knows if they will buy it... -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.
