#web_security #cors #sop #csrf Understanding Cross-Origin Resource Sharing is essential if you’re a web developer or want to understand the browser security model. Cross-origin Resource Sharing is a way to relax the SOP, Same Origin Policy, the security mechanism whereby browsers prevent Cross-Site Request Forgery, or CSRF. In this video, what is CORS, and Why we need it?. You’ll understand how we can bypass the Same Origin Policy with CORS and how HTTP headers are used to customize CORS implementation. - Video Outline - 00:09 Browser functionalities and security model 01:07 CSRF attack Cross-Site Request Forgery 01:41 Same Origin Policy 02:13 What is an Origin 03:05 CSRF and SOP 04:03 Relaxing SOP 04:41 Introducing CORS 05:17 CORS implementation HTTP Headers 06:45 Preflight Request 07:19 CORS in Web Browsers vs CLI client Resources to know more: * 🤍 * 🤍 Check out more of The TechCave Videos: * 🤍 - What is a VPN and How does it work?

CORS : Cross Origin Resource Sharing: Cross Origin Request: A request for a resource (like an image or a font) outside of the origin is known as a cross-origin request. Cross-Origin Resource Sharing ( CORS ) is a mechanism that enables web browsers / web clients to cross-origin requests. WHAT IS A SECURITY POLICY? Servers are used to host web pages, applications, images, fonts, and much more. When you use a web browser, you are likely attempting to access a distinct website (hosted on a server). Websites often request these hosted resources from different locations (servers) on the Internet. Security policies on servers mitigate the risks associated with requesting assets hosted on different server. Let’s take a look at an example of a security policy: same-origin. The same-origin policy is very restrictive. Under this policy, a document (i.e., like a web page) hosted on server A can only interact with other documents that are also on server A. In short, the same-origin policy enforces that documents that interact with each other have the same origin. An origin is made up of the following three parts: the protocol, host, and port number. The details of these individual parts aren’t necessary at the moment, but it is important to illustrate how the same-origin policy uses these parts. Consider the following URL: 🤍 Let’s call it URL1 (for short). If you used a web browser to navigate from URL1 to 🤍 you would be allowed to do so because the protocol (HTTP), host (example.com), and port (80) of each URL match one another. (Port 80 is the default port.) The same-origin policy requires that all parts of the origin match. Navigating to 🤍 from URL1, however, would not be allowed because of the different protocol (HTTPS) and host (en.example.com). As you can see, not having a security policy can be risky, but a security policy like same-origin is a bit too restrictive. Thankfully, there are security policies that strike a mix of both, like cross-origin, which has evolved into the cross-origin resource sharing standard, often abbreviated as CORS. WHAT IS CORS? A request for a resource (like an image or a font) outside of the origin is known as a cross-origin request. CORS (cross-origin resource sharing) manages cross-origin requests. Once again, consider the following URL: 🤍 Let’s call it URL1 (for short). Unlike same-origin, navigating to 🤍 from URL1 could be allowed with CORS. Allowing cross-origin requests is helpful, as many websites today load resources from different places on the Internet (stylesheets, scripts, images, and more). Cross-origin requests, however, mean that servers must implement ways to handle requests from origins outside of their own. CORS allows servers to specify who (i.e., which origins) can access the assets on the server, among many other things. You can think of these interactions as a building with a security entrance. For example, if you need to borrow a ladder, you could ask a neighbor in the building who has one. The building’s security would likely not have a problem with this request (i.e., same-origin). If you needed a particular tool, however, and you ordered it from an outside source like an online marketplace (i.e., cross-origin), the security at the entrance may request that the delivery person provide identification when your tool arrives. WHY IS CORS NECESSARY? The CORS standard is needed because it allows servers to specify not just who can access its assets, but also how the assets can be accessed. Cross-origin requests are made using the standard HTTP request methods. Most servers will allow GET requests, meaning they will allow resources from external origins (say, a web page) to read their assets. HTTP requests methods like PATCH, PUT, or DELETE, however, may be denied to prevent malicious behavior. For many servers, this is intentional. For example, it is likely that server A does not want servers B, C, or D to edit or delete its assets. With CORS, a server can specify who can access its assets and which HTTP request methods are allowed from external resources. HOW DOES CORS MANAGE REQUESTS FROM EXTERNAL RESOURCES? An HTTP header is a piece of information associated with a request or a response. Headers are passed back and forth between your web browser (also referred to as a client) and a server when the web page you are on wants to use resources hosted on a different server. Headers are used to describe requests and responses. The CORS standard manages cross-origin requests by adding new HTTP headers to the standard list of headers. The following are the new HTTP headers added by the CORS standard:
