This Zine discusses the Same Origin policy which is a browser security model to protect user data from malicious sites/scripts by restriction access for cross-site interaction. This zine explains in and out of SOP in a very casual way of showing them in the infographics.
I have covered:
SOP, Need for SOP, Bypassing SOP, CORS headers - Access-Control-Allow-Origin, Access-Control-Allow-Credentials.
