Katherine advises on cyber policy wording and incident response plans, and has experience in identifying the scope and extent of data breaches, and ascertaining whether such breaches are notifiable under the Privacy Act. Katherine has dealt with the OAIC and Australian Cyber Security Centre and ensures that notification obligations with respect to affected individuals are satisfied while balancing the need to minimise business interruption and avoid unnecessary publicity.
