The browser automatically sends the preflight (OPTIONS), if this is a cross-origin non-form request, for reading the Access-Control-Allow-Origin header. On such a request, the browser will first do a preflight request, for loading the CORS headers and then do the actual request. Cross-origin resource sharingД¬ross-origin resource sharing is a mechanism, controlled by HTTP response headers on a server, for allowing origins to perform вЂњnon-HTML form compliantвЂќ requests to the server. The most common way to do this is using OAuth bearer tokens in the headers. cross-site request forgery attacks, as we will soon see more about).Д®xplicit authentication means manually (explicitly) sending the authentication token by the developer such as via an HTTP header. The problem with this kind of authentication is, it is possible for an attacker, to do authenticated writes on behalf of a user if the servers are not explicitly protecting against this (eg. This could be cookies, HTTP basic auth, and TLS client certificates.

Implicit authentication means the authentication is based on something the browser automatically (implicitly) sends on each request. Doing so will result in this error (you try to fetch from another origin):Д®mbedding is generally allowed when embedding scripts, CSS, and images thus are normally a common attack surface as well (as we will see later). Reading from another origin is not allowed per default (more on CORS headers soon). The general rule of thumb with SOP and cross-origin writes is everything that you can do with an HTML form is allowed. The general rule of thumb with SOP and cross-origin writes is everything that you can do with an HTML form is allowed What?ДЇor writes, links, redirects, and form submissions are allowed. In a same-origin policy, reads are typically prohibited across origins and writes are typically allowed across origins. The same-origin policy (SOP) is a security concept that limits how one origin can interact with other origins.ДЄn origin consists of a protocol, domain and port: LetвЂ™s look at some basic security concepts to improve our understanding of how the browser works. The other threats are mostly handled on the backend and are not covered in this post. Using Components with Known Vulnerabilities.Of these threats, the ones that relate to Angular development are:

The OWASP top ten has evolved through the years and has gotten rid of a couple of security risks, that are no longer relevant enough to make the top ten in the 2017 edition. It consists of a group of security experts who release a top 10 list of relevant security risks every 3-4 years which many companies use to focus their security effort.

The OWASP top ten is the top ten list of web security risks from the Open Web Application Security Project foundation.

I will go through the OWASP top 10 security threatsВ that relate to Angular development and explain how to mitigate each one in this post. This post aims to give you the know-how to build security into your feature developmentВ and become a better developer by gaining a higher understanding of the browser and security concepts that are relevant for Angular developers. This way of working is only possible if we, frontend developers, also take responsibility for the security as we build features. High-performing teams, in this day and age, are usually autonomous DevOps teams and use continuous delivery for faster feature delivery. The reality is that learning about security actually forces you to gain knowledge about how the browser works thus it can make you a better Angular developer in general.
