Beginner Security Question - 9.Feb.2003 12:24:00 AM

Hello,

I have some servers working on my system such as web, ftp, pop, smtp. When an intruder scans my IP adress, I want those servers to be safe and do not appear at the scanner program. For this reason I have installed ISA Server, configured a Protocol Rule that allows only http, and at the Publishing section I've defined a rule for each of my servers. But when I scan my IP adress, those servers' ports appear clearly, they are not hided. As I said when scanned I don't want those ports to appear at the scanner software. So
which configurations do I have to do at ISA server?

Thanks

Hi X,

How would external network clients connect to published services if they didn't show as available?

If you did not publish these services and they show up on a scan, then make sure that packet filtering is enabled.

HTH,
Tom

Hello,

>and at the Publishing section I've defined a >rule for each of my servers.

As this quote from my message shows, I've published those sevices.

But if we forget all these, and think that I'm a complete beginner to ISA, can you plase tell me what are the things to secure my servers?

Thanks
