system breach
Unauthorized network access
A system breach is unauthorized access to a computer network, database, or security infrastructure.
The term emphasizes that protective barriers have been penetrated: The company disclosed a system breach affecting millions of customer records.
Breach implies both the act of breaking through and the resulting vulnerability—once defenses fail, damage may already be done.
