Re: FW: Cost of Worm Attack Protection

[<kgraham () rogers com>]

It would be great not to spend any money and let the worms run their course.  But when you have to deal with downed 
production at the cost of give or take possibly 500K per attack it unfortunately cannot be done without one loosing 
their job.  The last worm that spread throughout enterprises mentioned having to reinstall the entire server.  If that 
server is a critical production server what would you do?

Would spending 100K prevent the attack, very likely not.  Would spending 100K help track the offending machine(s) and 
enable someone to remove them from the network until they are serviced, possibly?  
Would this help keep production rolling, possibly?

The installation management and response time needed to implement an IDS solution does have to be investigated to see 
if the ROI comes in line with the cost.  The ROI would need to include any saved downtime.  If someone has this 
information please pass it along. 

A nicer solution would be an operating system that does not need a critical patch every other week, due to it's 
exploitable nature. 

Yes I am dreaming :)
