Re: Malicious Insiders are the most dangerous Threat Vector.
What you have suggested here-
Back end systems like those that handle logistics (procurement, shipping, inventory etc) could cause significant damage if they went down.
That is so true!
Its also a really,really good sign that Most Large Retailers are now taking the Supply Chain Back-end Seriously after the Target Breach.
The harder it becomes for malicious attackers to access such systems the better it is for all of us concerned.
For that if you need an Army of IT Folks to police everything so be it.
The cost is worth the loss in Reputation if something goes very wrong.
