This is the fourth consecutive blog post in our series on how to make Oracle E-Business Suite more secure. In this post, we will focus on reducing the attack surface - something that is a critical component for any successful information security strategy. The more you can reduce the components that are exposed to attackers (and to vulnerabilities), the more you can focus on keeping your exposed systems secure.
SAP has its own specific JAVA virtual machine implementation called SAPJVM, which according to SAP documentation: "...is derived from Sun’s HotSpot VM and JDK implementation ... the SAP JVM is only targeting server-side applications.

In this post, I will go through an analysis of Oracle's January 2015 Critical Patch Update (aka CPU).
