Monitoring, Threat Intelligence & Peer Networks System Security Data For employees, we have controls around who we hire; how their access is granted; and monitoring of system use. We operate dedicated controls to protect customers from fraud, including multi-factor authentication for sensitive transactions. Core security capabilities are operated by our security team, and protect all systems, e.g., malware prevention. Our security and application teams work together on the security of our systems, e.g., through design reviews, patching and secure development. We monitor our systems for indications of attacks and control weaknesses. We support this with cyber threat intelligence and information sharing partnerships. Suppliers are subject to security reviews, limited access to our systems and data, and ongoing performance monitoring. Distributed security represents security embedded in technology services, e.g., firewalls in our networks and access reviews. WESTPAC: A LAYERED DEFENCE1 1 No system can be 100% effective, systems are susceptible to human error and significant third-party risks. Cyber threats are continually evolving.
