Time: 10.00 AM to 2.00 PM IST
Delivery Mode: via Zoom.us and Discord Platform


Description

Writing web applications in Java can be rather complex – reasons range from dealing with legacy technologies or under documented 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.

      Peter Hegedus has a passion for computers and programming since his early ages. He holds a Ph.D. degree in Computer Science from the University of Szeged, Hungary. He is working part-time there as a research fellow, published over 40 research papers, mainly in software architecture, quality, and security. He teaches Enterprise System Development and Big Data analytics. Besides his academic carrier, Péter works as a software engineer. He took part in various projects, implementing an enterprise-scale quality analysis and monitoring platform, a log analysis solution for an international telecommunications company, and a secure workflow management framework for cyber-physical systems. He joined SCADEMY 5 years ago and delivered courses across Europe, India, and the USA. His current research focus is predicting vulnerable code parts with the help of machine learning models. According to his vision, not only that many security problems can be caught automatically by such models, but they will also produce automatic corrections soon.
