Secure Web Application Development
Course Features
Course Details
Overview
The Secure Web Application Development course is an immersive training seminar-like course focused on providing web developers training in web application security to enable them to build secure web applications, incorporating essential security elements into the applications, from the development to deployment stage and beyond. In addition to a basic level of programming skills, developers will also learn about the right practices and processes for the entire software development lifecycle. Further, participants will also be introduced to examples for better understanding the consequences of not following them.
At the end of the program, participants will be equipped with the ability to recognize both potential as well as real security vulnerabilities and employ the right defense measures to overcome them, and also test the adequacy of those defenses. This course will also introduce developers to the most common security vulnerabilities encountered in web applications today, and enable them to examine each from a coding perspective. Developers will learn to describe the threat and attack mechanisms, recognize associated vulnerabilities, and consequently, design, implement, and test effective defenses.
