Securing Enterprise Applications [New White Paper]

By Adrian Lane

Securing enterprise applications is hard work. These are complex platforms, with lots of features and interfaces, reliant on database support, and often deployed across multiple machines. They leverage both code provided by the vendor, as well as hundreds – if not thousands – of supporting code modules produced specifically for the customer’s needs. This make every environment a bit different, and acceptable application behavior unique to every company. This is problematic because during our research we found that most organizations rely on security tools which work on the network fringes, around applications. These tools cannot see inside an application to fully understand its configuration and feature set, nor do they understand application-layer communication. This approach is efficient because a generic tool can see a wide variety of threats, but misses subtle misuse and most serious misconfigurations.

We decided to discuss some of our findings. But to construct an entire application security program for enterprise applications would require 100 pages of research, and still fail to provide complete coverage. Many firms have had enterprise applications from Oracle and SAP deployed for a decade or more, so we decided to focus on areas where the security problems have changed, or where tools and technology have superseded approaches that were perfectly acceptable just a couple years ago. This research paper spotlight these problem areas and offers specific suggestions for how to close the security gaps. Here is an except:

Supply chain management, customer relationship management, enterprise resource management, business analytics, and financial transaction management, are all multi-billion dollar application platforms unto themselves. Every enterprise depends upon them to orchestrate core business functions, spend tens of millions of dollars on software and support. We are beyond explaining why enterprise applications need security to protect these investments – it is well established that insiders and persistent adversaries target these applications. Companies invest heavily in these applications, hardware to run them, and teams to keep them up and running. They perform extensive risk analysis on their business implications and the costs of downtime. And in many cases their security investments are a byproduct of these risk profiles. Application security trends in the 1-2% range of total application investment, so we cannot say large enterprises don’t take security seriously – they spend millions and hire dedicate staff to protect these platforms. That said, their investments are not always optimal – enterprises may bet on solutions with limited effectiveness, without a complete understanding of the available options. It is time for a fresh look.

In this research paper, Building an Enterprise Application Security program, we will take a focused look at the major facets in an enterprise application security program, and make practical suggestions on how to improve efficiency and effectiveness of your security program. Or goal is to discuss specific security and compliance use cases for large enterprise applications, highlight gaps, and explain some application-specific tools to address these issues. This will not be an exhaustive examination of enterprise application security controls, rather a spotlight common deficiencies with the core pillars of security controls and products.

There are some closely related ideas in OWASP AppSensor - real time application-specific attack detection and response.
