=AppSec Latam 2012 Training: Java Secure Coding=
'''Course Length: 2 Day'''<br>
Training Audience: Technical<br>
Required Skill Level: Intermediate<br>


==Course Description==
In this class we discuss secure coding techniques using Java. It is a very hands-on course with many labs. Everything is done from a developers perspective, NOT a hackers perspective. We make an effort to show what to do, and avoid the usual security paradigm of only discussing what not to do. 

The course covers input validation, authentication, authorization, session management, databases, output encoding, error handling, logging, file handling, file uploading, and cryptography.


The class is hands-on and will include labs. Attendees should have a laptop capable of running VMs. We will provide a VM at the beginning of the class.
