Which service in Angularjs help in to protect from XSS Cross Origin request attach?
Angular’s built-in CSP compatibility
Content Security Policy (CSP) is a web standard that allows establishing trust policies. It is mostly used as a defense-in-depth layer for broadening security and helps in mitigating issues like a (XSS) injection.
What is sanitization in angular?
Sanitization is the inspection of an untrusted value, turning it into a value that’s safe to insert into the DOM. In many cases, sanitization doesn’t change a value at all. Sanitization depends on context: a value that’s harmless in CSS is potentially dangerous in a URL.
