“A customer-data-breach bowtie: the hazard is customer data in production systems and the top event is unauthorised access. Show phished credentials, application vulnerabilities and over-privileged accounts as threats, with MFA, training, patching, a firewall, access reviews and session controls as barriers. Show data disclosure, customer impact and service disruption with detection, revocation, incident response, notification, recovery and continuity barriers.”

Preguntas habituales
Why is unauthorised access the top event?

Where do monitoring controls go?

Can supplier risk be included?
