We use DeepFreeze - and if you balance any concerns about possible attack vectors against acceptable risk and the 
benefits afforded by having an product like DeepFreeze to minimize the risks.....sorry - I'm going stick with DF....and 
since we centralized the whole DF management hierarchy, we've been very pleased....and stable....

Hi Again Everyone:

Not trying to be a pain here, really I’m not,  I do understand all the benefits that can be obtained through this type 
of technology but this is a security forum so I’m just going to have to say this.  Apologies up-front to anyone I may 
offend or upset – that is not my intent…..

IMO - Products like DeepFreeze, from a Security point of view, basically allow a smart attacker an anonymous attack 
vector into your organization that bypasses most of your perimeter defenses.  I’m not saying that is a show stopper but 
for our world it should definitely be something that is considered and discussed in detail.  I can do what I want,  
launch my attack, pull the plug on the machine, plug it back in and restart it,  exit stage left….   Or am I missing 
something obvious that prevents this from happening?

Hi All,

We have some folks who’d like to see Deepfreeze installed on all lab PCs, but the IT department is balking. What do 
people think is the best reason to not install deepfreeze? Is there one?

Thanks,

Dan
