https://github.com/OWASP/CheatSheetSeries/blob/master/cheatsheets/Authentication_Cheat_Sheet.md The process of establishing confidence in the identity of users or information systems. Authentication is the process of verifying that an individual, entity or website is who it claims to be. Authentication in the context of web applications is commonly performed by submitting a username or ID and one or more items of private information that only a given user should know.
? https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-63-2.pdf https://www.owasp.org/index.php/Category:Access_Control The right or a permission that is granted to a system entity to access a system resource. Access Control, also known as Authorization — is mediating access to resources on the basis of identity and is generally policy-driven (although the policy may be implicit)...also govern the methods and conditions of enforcement by which subjects (users, devices or processes) are allowed to or restricted from connecting with, viewing, consuming, entering into or making use of identified information resources (objects).
The OAuth 2.0 authorization framework enables a third-party application to obtain limited access to an HTTP service, either on behalf of a resource owner by orchestrating an approval interaction between the resource owner and the HTTP service, or by allowing the third-party application to obtain access on its own behalf ▸ Papéis & Responsabilidades ▸ Fluxos, Endpoints ▸ Formato do Token! ▸ Meios para obter identidade do usuário!
When the resource owner is a person, it is referred to as an end-user. OAuth 2.0 OAuth 2.0 21 Papéis e Responsabilidades Source: https://tools.ietf.org/html/rfc6749#section-1.1 An application making protected resource requests on behalf of the resource owner and with its authorization. Client The server issuing access tokens to the client after successfully authenticating the resource owner and obtaining authorization. Authorization Server Resource Owner The server hosting the protected resources, capable of accepting and responding to protected resource requests using access tokens. Resource Server
resources. An access token is a string representing an authorization issued to the client Token Type The access token type provides the client with the information required to successfully utilize the access token to make a protected resource request (along with type-specific attributes) Refresh Token Refresh tokens are credentials used to obtain access tokens. Scope The authorization and token endpoints allow the client to specify the scope of the access request using the "scope" request parameter. In turn, the authorization server uses the "scope" response parameter to inform the client of the scope of the access token issued. OAuth 2.0 22 Access Token OAuth 2.0 Source: https://tools.ietf.org/html/rfc6749#section-1.4 https://tools.ietf.org/html/rfc6749#section-7.1 https://tools.ietf.org/html/rfc6749#section-1.5 https://tools.ietf.org/html/rfc6749#section-3.3
Source: https://openid.net/specs/openid-connect-core-1_0.html#Introduction OpenID Connect 1.0 is a simple identity layer on top of the OAuth 2.0 protocol. It enables Clients to verify the identity of the End-User based on the authentication performed by an Authorization Server, as well as to obtain basic profile information about the End-User in an interoperable and REST-like manner. ▸ Papéis & Responsabilidades ▸ Fluxos, Endpoints ▸ Token de Identidade ▸ Formato, Claims e Escopos
Layer sob OAuth 2.0 Source: https://tools.ietf.org/html/rfc7519 JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JSON object that is used as the payload of a JSON Web Signature (JWS) structure or as the plaintext of a JSON Web Encryption (JWE) structure, enabling the claims to be digitally signed or integrity protected with a Message Authentication Code (MAC) and/or encrypted. ▸ Formato (Header, Claims, Assinatura) ▸ Criptografia ▸ Assinatura ▸ Tipos
Single Sign On 29 Identity Access Manager Source: https://access.redhat.com/documentation/en-us/red_hat_single_sign-on/7.3/html-single/release_notes/index#overview RH-SSO is based on the Keycloak project, and enables you to secure your web applications by providing Web SSO capabilities based on popular standards such as OpenID Connect, OAuth 2.0, and SAML 2.0. The RH-SSO server acts as an OpenID Connect or SAML-based identity provider (IdP), allowing your enterprise user directory or third-party IdP to secure your applications via standards-based security tokens. ▸ Padrões da Indústria (OAuth, OpenID, SAML, Kerberos) ▸ Federação de Usuários ▸ Broker de Identidades ▸ Gestão de Usuários e Sessões

37 ACHIEVE FASTER API RELEASES Successful firms with an agile integration strategy release/update APIs weekly or daily, nearly three times more frequently than less successful firms. We remain concerned about business logic and process orchestration implemented in middleware, especially where it requires expert skills and tooling while creating single points of scaling and control. Vendors in the highly competitive API gateway market are continuing this trend by adding features through which they attempt to differentiate their products. This results in overambitious API gateway products whose functionality — on top of what is essentially a reverse proxy — encourages designs that continue to be difficult to test and deploy. API gateways do provide utility in dealing with some specific concerns — such as authentication and rate limiting — but any domain smarts should live in applications or services.
