This is a tutorial about setting your nodeJS application up to mitigate the risk of cross site scripting (XSS) attacks with helmet.xssFilter(). This is one part of many making up the Information Security with HelmetJS section. This section makes up part of the Information Security Certification. I want to say a big thank you to FreeCodeCamp (www.freecodecamp.org) for the curriculum. My goal with these videos is to support early stage programmers. I hope that these videos help you to learn faster and understand more fully. For me, learning this was difficult so I hope this makes your life less difficult. Thank you for watching.
