I will be speaking on upcoming WordCamp Niš next week, on the topic of Content Security Policy and how CSP can be used to improve WordPress website security.
You can see the detailed schedule for the WordCamp on the official website, and I am scheduled to talk at noon. And, in preparation for the talk, I have released the free plugin on WordPress.org for implementing CSP and various other security headers called GD Security Headers.
So, if you are coming to WordCamp Niš, stop by to hear more about WordPress and CSP. In the meantime, check out the plugin.
