JS+Angular com autenticação por JWTs - como fica a segurança?

Recommended Posts

bom dia pessoal

estudando sobre modern web apps, angular e tals, separar em 2 projetos , onde tenho a UI apenas com HTML e JS e o acesso ao backend via web.api

estava indo "tudo bem" até que cheguei na parte onde achei que ia ficar com o pé atras mesmo, autenticação e manter o usuário logado.

 

utilizar local storage possui vários problemas de segurança em questão de alteração de dados, CSRF e XSS.

utlizar cookie, bem, se ativar o HttpOnly, teoricamente nao tenho acesso a essas informações via JS.

 

o que me leva a 2 perguntas

1)utilizar um cliente UI 100% não é seguro(isso é uma coisa que defendo a muito tempo, mas estou tentando pensar fora da caixinha), e se tiver uma aplicação na qual precisa de autenticação ou possui dados sensíveis, melhor nao seguir esse caminho

2)vcs conseguem manter a segurança de outra forma?

 

acho que é isso

A segurança da sua aplicação NÃO PODE depender do JavaScript (browser) e sim do que está no servidor.

 

O JWT deveria ser usado em HTTPS,

Tudo que usa Login hoje em dia deveria estar rodando em cima do HTTPS!!!!

Quem não usa perde ranqueamento no Google alem de diminuir muito a segurança....

ou possui dados sensíveis

Se o 'trajeto' está seguro (pelo https) e o JWT ser apenas um token em que o próprio usuário gerou/recebeu não vejo motivos a não usar independente do que você considera como 'dados sensíveis'

 

Pensando em cenários...

 

O sistema pode ser Stateless ou Session.

Você deve trata a entrada/saída de informação de conteúdo em cima de contexto

 

Ex:

João só pode ver os 'carros' do 'João'.

João só pode ver alterar a senha do 'João'.

João só pode ver informações publicas de 'José'.

 

As regras de negócios acima devem ser validadas independente da forma que os dados chegam saca?

sim, esses itens foram considerados, o que me incomoda e apenas o fato do negocio estar a vista no browser..rs

mas vou dar sequencia no projeto dessa forma....vamos ver como fica

 

obrigado pelas informações

      Olá
       
      Achei esse script aqui no fórum mesmo:
       
      $.validator.addMethod( "customEmail", function (value, element) { return this.optional(element) || /^[\w-\.]+@fulano\.com\.br$/i.test(value); }, "Por favor, insira um e-mail válido com o domínio @fulano.com.br" ); $("#formulario").validate({ ignore: ".ignore", rules: { empresa: { required: true }, nome: { required: true }, contato: { required: true }, celular: { required: true }, email: { required: true, email: true, customEmail: true }, }, }); Testei e funcionou perfeitamente, mas gostaria que liberasse mais e-mails válidos, ao invés de apenas um.

      Tem como fazer? 
       
      Se alguém puder ajudar, fico muito grato.

      Por favor, alguém sabe como esse código pode ter sido inserido por um invasor para que eu possa fechar a possível brecha no código?
      O site foi desenvolvido utilizano wordpress.
      Desde já agradeço a todos que puderem ou tentarem me ajudar a descobrir o que pode ter acontecido.
