Validating identity and d link

Access decisions are typically based on the authorizations granted to a user based on the credentials he presented at the time of authentication (user name, password, hardware/software token, etc.).

An RBAC access control framework should provide web application security administrators with the ability to determine who can perform what actions, when, from where, in what order, and in some cases under what relational circumstances.

The advantages of using this methodology are: Discretionary Access Control (DAC) is a means of restricting access to information based on the identity of users and/or membership in certain groups.

In Role-Based Access Control (RBAC), access decisions are based on an individual's roles and responsibilities within the organization or user base.

The process of defining roles is usually based on analyzing the fundamental goals and structure of an organization and is usually linked to the security policy.

Web applications need access controls to allow users (with varying privileges) to use the application.

They also need administrators to manage the applications access control rules and the granting of permissions or entitlements to users and other entities.In the indirect model the permission grant is to an intermediate entity such as user group.A user is considered a member of a user group if and only if the user inherits permissions from the user group.It should be noted that authorization is not equivalent to authentication - as these terms and their definitions are frequently confused.Authentication is providing and validating identity. Authorization includes the execution rules that determines what functionality and data the user (or Principal) may access, ensuring the proper allocation of access rights after authentication is successful.In the interests of making it reasonably digestible I’ve decided to introduce tokens and specifically look at the registration email confirmation token flow in this post.
