  The landscape of threats to sensitive data is changing.  New technologies bring with them new vulnerabilities, and organizations like Target are failing to react properly to the shifts around them. What's needed is an approach equal to the persistent, advanced attacks companies face every day.  The sooner we start adopting the same proactive thinking hackers are using to get at our data, the better we will be able to protect it.

  • 58. Conclusions Changing threat landscape & challenges to secure data: • Attackers are looking for not just payment data – a more serious problem. • IDS systems are lacking context needed to catch data theft • SIEM detection is too slow in handling large amounts of events. What happened at Target? • Modern customized malware can be very hard to detect 58 • They were compliant, but not secure How can we prevent what happened to Target and the next attack against our sensitive data? • Assume that we are under attack - proactive protection of the data itself • We need to analyze event information and context to catch modern attackers • The Oracle Big Data Appliance can provide the foundation for solving this problem
