If user operational security was adequate, we could retire our firewalls,
let our users remote compute with full VPNs in and out, and replace these
relatively slow, fragile, complex, maintenance-intensive sets of boxes with
wire-speed switches.
Plus IDS.
If we feel user operational security isn't adequate, I think it's a fair
topic of discussion, because the drive to try to mend or at least detect
issues ends up in our hands.
We can secure every machine that has IP connectivity to the inside net,
more or less, but user operational security lapses will let vandals or
thugs molest our users.
>From everything I've heard, the targets of some recent high-profile
intrusions had petty good security architecture in place.
Whether it's carrying USB sticks between home and work, or clicking on
links using an overly-complex and hence insecure browser or MUA, folks need
to get their work done.
Some behavior problems can sometimes be partially addressed by training,
but mostly, if there's a problem, we should look for a way to adjust our
firewall and the services it permits, or provide companion services
(owncloud sounds interesting) to help them get their work done without
exposing themselves to folk with hostile intent.
I think discussion of what we should try to do, and why, is every bit as
relevant as - and maybe more useful than - chatting about how best to do it.

I have a love/hate relationship with these as well. I was only tempted
down this perfidious path a few years ago when a set of my Grandchildren
asked me to get a Facebook account so we could interact that way as they
live on the other coast from me. I started disliking it within five
minutes when a former employer sent me a request to "friend" him. Then it
became an issue of who can I not be "friends" with among my contemporaries.
Same with Linked-In, same with Twitter.
Up to this point I'm just addressing the personal inconvenience aspect of
it, which is why I chose Crispan's post to which to reply.
But, the larger issue is really the risk of exposing all sorts of personal
/ corporate information in a variety of unwitting ways. This is the part
I hate. We've had many discussions about the risks of allowing people to
use social media web sites from work. It's a losing battle. Entering
one's email password is just one, and Linked-In is not the only villain. I
just made some flight reservations yesterday. The airline website offered
to add the reservation to my Calendar. Not let me download a .cal file,
but to directly insert it into my calendar. Uh, no. Not today.
But, this now get's added to our list of worst practices and meet's Paul's
criteria of being part of overall operational security. I'm honestly not
sure how we could block this stuff in a web-proxy, or be alerted by an IDS
rule short of just blocking the sites. (Maybe this will start more
discussion. How would one try this?)
Mix these with BYOD, and it makes a daunting task indeed.
Cheers
