Chief information security officer Jay Leek says security teams must double down on smarter detection of threats and attacks. Leek, who is the CISO at financial services and asset management firm Blackstone, says the more you know about your attackers and their M.O., the better chance you have in thwarting any real damage. “If you’re focused on prevention and not much on detection, you are flying blind sometimes,” says Leek. “Bad guys have much more time on their hands than we do,” he says.”]
