The software I use has an "endpoint analysis" mode, kinda like a passive mode, 
that creates whitelists for you. Using this, you should be able to ensure 
everything works before going live. Add to this the alerting is very good so 
false positives get quickly dealt with.

What happens when the business relies a lot on Access DBs, Excel spreadsheets 
etc.?
Do I have to whitelist every macro? Am I still at risk of data 
loss/corruption/exfiltration?

Cheers

Whitelisting can be a lot of work, if you haven't got a flexible technology. 
There are various vendors in the space and some of them take a lot of the 
donkey-work out of it for you, whilst still maintaining (as far as I've seen) 
decent security. But I totally agree that it's still at the whim of the person 
with their fingers on the controls - if the admin allows a bad executable, then 
you're in trouble.

That can only be mitigated by belt-and-braces approaches, really, relying on 
old-style reactive AV or IDS/IPS or whatever to catch the bad executable that's 
somehow bypassed your processes and controls.

There is another load of tech springing up around MDM, MIM, MAM or whatever TLA 
you choose to describe it. It's another big set of challenges though. At the 
moment I am concentrating on extending the agents I have to MacOS devices 
rather than worrying about tablets and mobiles yet. I can avoid some of the 
pain at the moment by deploying Windows apps and desktops via Citrix to the 
mobile devices rather than letting users manipulate corporate data directly, 
but it's something I will no doubt get asked to get involved in sometime in the 
future :-)

But it's all so fun keeping up with user trends, isn't it? Maybe if we try 
really hard to get on top of the possibilities right now we can approach BYOD 
from a security perspective rather than just getting bullied into making it 
happen too quickly and having to catch all the security issues while 
firefighting :-)

Cheers,

James,

I agree on the application whitelisting front. But its a lot of work and its 
still based on trust. ( If you trust something bad) then you have still let the 
determined attacker in the door, but the caveat is if you control the code 
execution on your endpoints, then you change the game into your favor.

Other aspects to think of:

Will application whitelisting work for mobile devices: (Iphone, Android, 
Tablets, all of which can act like storage devices in a way.

Questions to be answered:

Which devices do you allow to be attached to your systems to transfer data? 
(Policies, procedures, enforcement with technical controls and auditing and 
followup with administrative controls for compliance? (Do we allow the Apple 
devices, but not the Android, or do we allow just Ironkey devices, and whom 
should have them and what data should they be able to take ( DLP/DRM etc etc)

And we all should know by now that AV is next near worthless against current 
malware trends, so why does the compliance regulations still require this ( 
PCI-DSS especially).

Working on App whitelisting right now, its been interesting and complex at the 
time, but at the end I feel it will be worth it.
