Windows Data Execution Prevention Could Have Helped Thwart RSA Hack

New research suggests that the attacks on RSA might have been prevented
if the targeted machines had been running Windows 7 instead of Windows
XP. The Data Execution Prevention (DEP) that is baked into Windows 7
could have stopped the breach that led to the data breach. The machines
compromised in the attack appear to have been running XP without DEP
enabled.
