Facebook's chief security officer, Max Kelly, is scheduled for a keynote presentation on Wednesday morning following two days of training sessions. The last two days of the conference will focus on briefings featuring research into a variety of threats on the Internet and application vulnerabilities.

One of those presentations will focus on a way to insert a backdoor into SAP's ERP (enterprise resource planning) applications. SAP's business software is often the core of a company's operations and is used to manage invoicing, human resources, procurement and billing, among many other functions.

SAP's software uses databases from companies such as Oracle, said Mariano Nuñez Di Croce, director of research and development for Onapsis, a company that focuses on penetration testing for SAP systems and others such as Oracle's PeopleSoft and JD Edwards enterprise applications.

Many companies do not configure the Oracle database correctly, which makes the SAP system vulnerable to attack.

"What we have found is, it is possible instead of modifying the program you can connect to the database and modify the code directly in the database," Nuñez Di Croce said.
