There are lots of courses that teach you how to build secure software from the ground up.  There are also lots of courses that will teach you how to assess the security of existing software.  This course is unique because it focuses on a HUGE problem all organizations have: dealing with a large number of identified vulnerabilities in deployed code.

Course Description:

This class teaches attendees how to fix security vulnerabilities in existing software. It provides a mix of discussion of project concerns for planning and managing remediation efforts with hands-on coding examples fixing specific vulnerabilities. Attendees will learn how to risk-rank vulnerabilities, estimate remediation tasks, perform coding fixes for vulnerabilities and demonstrate the effectiveness of fixes applied. The focus is on the practical: how to use limited resources to make significant improvements to the security of target applications. Code examples use the OWASP ESAPI Java and Microsoft Web Protection Library. Many classes teach developers how to build secure code from the ground up or teach security analysts how to test applications for security vulnerabilities. This class teaches developers and security analysts how to deal with their existing portfolio of insecure applications.
