What is a Data Breach?

A data breach is a critical security incident in which sensitive data is accessed without authorization or lost. These events are usually initiated by cybercriminals.

Software vulnerabitlies make data breaches possible, but the most common attack vector is human error. Social engineering - a tactic involving tricking staff members into divulging internal login credentials - is still one of the most effective methods of establishing malicious access into a private IT network. To mitigate this threat, organizations must educate their staff on common cyberattack methods and how to respond to them.
