A compound of 'cyber-' + 'security.' 'Cyber-' from 'cybernetics,' coined in 1948 by Norbert Wiener from Greek 'kybernētēs' (κυβερνήτης, steersman, pilot, governor), from 'kybernan' (κυβερνᾶν, to steer, to govern). 'Security' from Latin 'sēcūritās' (freedom from care), from 'sēcūrus' (free from care), from 'sē-' (without) + 'cūra' (care, concern). The prefix 'cyber-' detached from 'cybernetics' and became a free-standing combining form meaning
