Commenti

Nell'elenco seguente vengono descritte le funzionalità per le quali gli eventi WebAuthenticationFailureAuditEvent vengono generati per impostazione predefinita da ASP.NET.

• Autenticazione basata su form. Mentre i controlli di esito positivo includono il nome utente autenticato; I controlli di errore non includono il nome utente, perché in genere derivano da un ticket che non ha superato la decrittografia o la convalida. Entrambi contengono l'indirizzo IP del client. Il codice di controllo eventi correlato è AuditFormsAuthenticationFailure.

• Iscrizione. I controlli di esito positivo e negativo contengono il nome utente che è stato tentato. Nessuna forma di controllo conterrà la password che è stata tentata, perché rischierebbe di rendere persistente una password valida nel log. Il codice di controllo eventi correlato è AuditMembershipAuthenticationFailure.

Quando un WebAuthenticationFailureAuditEvent oggetto viene generato, per impostazione predefinita aggiorna il contatore delle prestazioni Audit Authentication Failure Events Raised . Per visualizzare questo contatore delle prestazioni in Monitoraggio di sistema (PerfMon), nella finestra Aggiungi contatori selezionare ASP.NET nell'elenco a discesa Performanceoggetto, selezionare il contatore delle prestazioni Eventi di errore di autenticazione generati e fare clic sul pulsante Aggiungi. Per altre informazioni, vedere Using the System Monitor (PerfMon) with ASP.NET Applications.
