6 Best Books on Authentication and Authorization with OAuth 2.0 
Security is a vital part of any application and cloud environment and should never be an afterthought. Authentication and authorization form a critical component of identity and access management and cybersecurity in general.
Authentication is basically the process of checking/validating the identity of a person. Authorization is the process of checking whether the user requesting to access a resource or a set of resources is allowed to access the resource or not.
