In Part 1 of this series, we reviewed the continued disconnect between corporate IT security spending and the cause of most security incidents. Most breaches are known to be caused by the misuse or takeover of user access authorizations. In this concluding chapter, we suggest some machine-learning based approaches to user access that will help improve organizational security. In addition, we highlight SAP's delivery of related machine-learning components that address improved information security. Fortunately for SAP customers, machine learning has been embedded in SAP S/4HANA to monitor breach activity from social media and the "dark" (non-indexed) web.
