What are service workers and how do they impact security?

Service workers are scripts that run in the background of a web application, allowing for features like offline access and push notifications. They can impact security by intercepting network requests, which can be both beneficial and risky if not implemented correctly.

What security risks are associated with service workers?

Some security risks include man-in-the-middle attacks, improper caching of sensitive data, and vulnerabilities in the service worker code itself.

How can I secure my service worker?

To secure your service worker, ensure you use HTTPS, validate inputs, limit the scope of the service worker, and regularly audit your code for vulnerabilities.

Are there any best practices for using service workers?

Yes, best practices include using a fallback for offline access, managing cache effectively, and keeping service worker scripts small and efficient.
