QUESTION 12 OF 30

Can you explain the techniques you use to ensure front-end security?

The purpose of front-end security on a website is twofold. The first is to keep the client and their data secure. The second is to prevent the client from accessing parts of the website that they shouldn't reach. Companies will be interested in how you perform this task since it protects both their users and the company from data loss, hacking, and liability issues. Since this is an operational question, be sure to keep your answer direct and to the point.

"As a front-end developer, security is one of my key concerns, second only to the performance of the website. By incorporating security practices in the code's original development, I eliminate the need to constantly fix leaks or combat hacks. My first step in this process is to use a framework that handles security automatically. Examples of this include View, Angular, and React. I've also begun incorporating Trusted Types into my development. This is a new browser API from Google which addresses XSS issues. Finally, I compartmentalize the individual applications rather than deploying them as a single piece of code. This makes them harder to hack and minimizes the damage when there are penetrated."
