Computer Security: 20 years of securing controls (or trying to): mitigations
We’ve seen in the past two Bulletins that control system cybersecurity is the black sheep of IT, a hard-to-change tanker’s course. Still, with significant daily damage of 250 000 USD for ALMA, the costs of falling to a cyberattack can no longer be ignored
