OWASP Top 10, Java Secure Coding Fundamentals, Finland

We can host this training at your preferred location. Contact us!

Writing web applications in Java can be rather complex – reasons range from dealing with legacy technologies or underdocumented third-party components to sharp deadlines and code maintainability. Yet, beyond all that, what if we told you that attackers were trying to break into your code right now? How likely would they be to succeed?

This course will change the way you look at your Java code. We'll teach you the common weaknesses and their consequences that can allow hackers to attack your system, and – more importantly – best practices you can apply to protect yourself. We cover typical Web vulnerabilities with a focus on how they affect Java web apps on the entire stack – from the Java runtime environment to modern AJAX and HTML5-based frontends. In addition, we discuss the security aspects of the Java platform itself as well as typical Java programming mistakes you need to be aware of. We present the entire course through live practical exercises to keep it engaging and fun.

Writing secure code will give you a distinct edge over your competitors. It is your choice to be ahead of the pack – take a step and be a game-changer in the fight against cybercrime.
