who is the next target proactive approaches to data security
DESCRIPTION
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.TRANSCRIPT

• Resulted in the theft of at least 40 million customer records containing financial data such as debit and credit card information.
• In addition, roughly 70 million accounts were compromised that included addresses and mobile numbers.
The data theft was caused by the installation of malware on

You must assume the systems will be breached.
Once breached, how do you know you've been compromised?
You have to baseline and understand what 'goodness' looks like and look for deviations from goodness
McAfee and Symantec can't tell you what normal looks like in your own systems.

ConclusionsChanging threat landscape & challenges to secure da ta:
• 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
