I think in a way, that's quite valid. If the external pen-test is just running a scan, then there's not much to it...especially if that web application is off-limits. Why would that be out of scope? Gartner says (oooohhhh...) that 75% of attacks come through web applications. How they come up with that and what that really means, I'm really not interested in arguing but web applications are a HUGE security risk. I'm not sure I'd be too quick to discount the Citrix and terminal server access either. They can be locked down pretty well but they are also a HUGE hole if they get compromised. I've seen admin accounts with no password or a weak password that was accessible through terminal services. I also think that part of a pen-test should include how the "helpdesk/security center/whatever" responds to an attempted attack....generally, they don't respond at all 'cuz they never look at the logs. Also, how are you defining external? How about sending e-mail to internal clients that "phone home" in one way or another? How about wireless....is that external? I think one of these tests can be a huge eye-opener if done right. If it's just a portscan and running some automated tool....well, that's of limited value. -----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of Yiannis Koukouras Sent: Thursday, August 09, 2007 3:19 AM To: pen-test () securityfocus com Subject: External Pentests Obsolete? Hi all, Do you think that an external infrastructure pentest is nowadays obsolete? What I want to say is that, most of the serious companies nowadays will only have a few servers on their DMZ (web server, mail server, SSL concentrator, terminal server, citrix) and will only allow access to one or two ports for each of them. The rest of the infrastructure (excluding the internet facing router and firewall) will be completely inaccessible. Thus, if web application testing is out of scope, there isn't much to test, is it? Only half a dozen of services to check vulnerabilities and misconfiguration, check if mail rely is on, make a password bruteforce attack(?), check that the DNS can't be poison and VOILA! You have finished! Do you think that it is ethical to consult our clients to "buy" an external pentest anymore? P.S.
