Look inside
In this liveProject, you’ll tackle risks caused by unsafe input and output handling in your application. These bugs can make your application vulnerable to reflected and stored attacks such as Cross-Site Scripting (XSS). You’ll identify insecure code and develop fixes to securely handle inputs from untrusted sources, safely manage your encoded data, and avoid unsafe calculations with numeric data types. You will be provided with resource material to identify the problems and will replace the vulnerable Java with secure code to protect against attacks.
