[Dailydave] The long tail of vulnerable operating systems

[Kurt Grutzmacher]

You guys are absolutely right. In the past few years I've seen very few
remote exploits that matter but that doesn't mean the old Solaris, AIX and
Win2K servers don't exist anymore. So many old PBX systems run UnixWare and
are being connected to networks so the phone techs don't have to walk over
to the phone room terminal to do adds/deletes. These are vendor supported
systems and usually don't get the same treatment that IT puts into the
Active Directory, web servers, etc.

How many times have we heard from our friendly vendors "We don't support
that. If you upgrade the software you'll be in violation and we won't
support it." So you firewall it off and poke little holes for the tape
admins to monitor the silo from the vendor's Solaris platform that really
needs to run sadmind.

Web apps are the newest frontier for testing but they're just another layer
that is usually finely tuned into the business process. How do you tell the
customer their process is flawed or needs improvement because you were able
to send an exe-disguised Word doc that was executed by 5% of the company?

Hmmm..
