Establish a CSP and Security Headers standard
Explore how to establish a Content Security Policy and standard security headers to protect against clickjacking and XSS vulnerabilities. Understand the deprecation of older headers like X-Frame-Options and X-XSS-Protection, and learn to create migration paths using CSP standards while considering browser support and evolving security practices.
We'll cover the following...

That being said, practices evolve and browsers rapidly adopt new standards and mechanisms. For example, the ALLOW-FROM value for the X Frame Options header has been deprecated and is now discouraged because modern browser versions don’t support it anymore.
