Spring is here, and with it comes news of a new and vicious ransomware attack, known as LockerGoga.
At a recent industry event, I got to chatting with the CISO of a major children’s hospital. Over a beer, he shared with me the challenges he faces daily. Our far-reaching conversation covered nation-state actors enticing students to exfiltrate clinical trial test results, to his search for a secure USB port cover for patient-facing devices.

It could have been worse; the massive “take” was interrupted not by IT security technologies, but by human vigilance. A watchful employee saw a spelling error in a transfer message and alerted an investigation team.
