cyberdefenses
Online security measures
Cyberdefenses are the measures taken to protect computer systems, networks, and data from digital attacks.
The term covers both technical safeguards—firewalls, encryption, intrusion detection—and organizational practices like security training and incident response protocols.
The company invested heavily in cyberdefenses after the breach.
Also spelled cyber defenses.
