Observações

A lista seguinte descreve as funcionalidades para as quais os eventos WebAuthenticationFailureAuditEvent são elevados por defeito por ASP.NET.

• Autenticação de formulários. Embora as auditorias de sucesso incluam o nome de utilizador que foi autenticado; As auditorias de falhas não incluem o nome de utilizador, uma vez que normalmente resultam de um ticket que falhou na desencriptação ou validação. Ambos contêm o endereço IP do cliente. O código de auditoria de eventos relacionados é AuditFormsAuthenticationFailure.

• Membros. Tanto as auditorias de sucesso como as de fracasso contêm o nome de utilizador que foi tentado. Nenhuma das formas de auditoria conterá a palavra-passe tentada, pois isso arriscaria persistir uma palavra-passe válida no registo. O código de auditoria de eventos relacionados é AuditMembershipAuthenticationFailure.

Quando a WebAuthenticationFailureAuditEvent é elevado, por defeito atualiza o contador de desempenho Audit Authentication Failure Events Raised (Audit Authentication Failure Events). Para visualizar este contador de desempenho no System Monitor (PerfMon), na janela Add Counters selecione ASP.NET na lista suspensa de objetos Performance, selecione o contador de desempenho Authentication Failure Events Raised e clique no botão Add. Para mais informações, veja Using the System Monitor (PerfMon) com ASP.NET Applications.
