Bei HTTP Basic Auth erwartet die Anwendung einen Header, der einen Benutzernamen und ein Passwort enthält.

Wenn sie diesen nicht empfängt, gibt sie den HTTP-Error 401 „Unauthorized“ zurück.

Und gibt einen Header `WWW-Authenticate` mit dem Wert `Basic` und einem optionalen <abbr title="Bereich">`realm`</abbr>-Parameter zurück.

- In the course of admitting a single request, the ValidatingAdmissionPolicy plugin will perform no more than one authorization check per unique authorizer expression. All evaluations of identical authorizer expressions will produce the same decision.

adds an alpha AuthorizeNodeWithSelectors feature that makes the node authorizer limit requests from node API clients to get / list / watch its own Node API object, and to get / list / watch its own Pod API objects. Clients using kubelet credentials to read other nodes or unrelated pods must change their authentication credentials (recommended), adjust their usage, or grant broader read access independent of the node authorizer.

Para os casos mais simples, você pode utilizar o HTTP Basic Auth.

No HTTP Basic Auth, a aplicação espera um cabeçalho que contém um usuário e uma senha.

Caso ela não receba, ela retorna um erro HTTP 401 "Unauthorized".

E retorna um cabeçalho `WWW-Authenticate` com o valor `Basic`, e um parâmetro opcional `realm`.

Isso sinaliza ao navegador para mostrar o prompt integrado para um usuário e senha.

mechanisms that prevent unwanted access to the data from other tenants.

Network isolation between different models is also important not only to prevent
unauthorized access to data or models, but also to prevent malicious users or
tenants sending graphs to execute under another tenant’s identity.

The isolation mechanisms are the responsibility of the users to design and
