MIB, seriously,
Lockheed lost bloody terrabytes of data to China (them among zillions of others), and your response is that they must not have installed enough freeware?, or ok ... not enough paid for maleware/spyware/viruseware/etc/ stuff?
Seriously, do you hold to the premise that the current security software technologies are more or less adequate?
Speak towards this, tell me, in the face of all of the press, institutional efforts and rules that enterprise and governments are developing and adopting ... is it your position that they've gone bonkers and that the current situation is actually just fine?
Is your idea that they just need to assemble the constellation of software you run and all is well?
The above content is my opinion.
