'Poor Man’s Authorization: How to Implement RBAC for REST API with OPA' rbac restapi
Or the developer grows a beard and starts using phrases like abac, xacml, and an access matrix;
If you are interested in how you can build RBAC from available tools for any service that respects REST, you’re welcome.: With the rapid implementation of Proof of Concept applications or functions, your security implementation often becomes less important.
Now let’s go back to our example with the application and figure out where to get the data for making such a decision.Recently, Keycloak and its SSO Redhat implementation have been gaining in popularity, so I’m going to proceed from the Keycloak token structure.. It is very convenient to use the action marker to operate with the classic REST notation and assume that the methods.. In the case of a proxy, it is convenient to interpret data as a route.
That is, if we assume that Gateway can perform the authorization request, all that remains is to add a new puzzle to our picture – the authorization module.The user has received his identity token, and we assume that it contains all the necessary information about the user. With this token, the user makes a request to the business application and gets to Gateway.
- It separates the HTTP method from the request and says that this is the action performed by the user;There are three rules in authorization, which say that the reader can read data, the editor can read and change data, and the administrator can do everything;That’s it. The theory is done. To be honest, there is much more theory than implementation. This is what this decision really impresses me with.
