Introduzione
In questo documento viene descritta la nuova azione deletelogfiles e viene descritta la procedura per eseguire l'azione su Cisco Secure Email Gateway (SEG).
Contributo di Chris Arellano Cisco TAC Engineer.
Prerequisiti
AsyncOS 15.0.0 e versioni successive per Cloud Email Security e On-Premise Secure Email Appliance.
Componenti usati
Cisco SEG
metodo di accesso CLI
Le informazioni discusse in questo documento fanno riferimento a dispositivi usati in uno specifico ambiente di emulazione. Su tutti i dispositivi menzionati nel documento la configurazione è stata ripristinata ai valori predefiniti. Se la rete è operativa, valutare attentamente eventuali conseguenze derivanti dall'uso dei comandi.
Configurazione
Nelle istruzioni successive viene illustrata la nuova funzionalità di registrazione che consente di eliminare singoli file di registro all'interno di ciascun dispositivo SEG.
Perché? In alcune situazioni può essere necessario eliminare i contenuti sensibili dal SEG.
Ogni sottoscrizione di log è costituita da una raccolta di singoli file contenente un indicatore di data per ogni file all'interno del nome, che termina con l'inizio del log successivo contenente una data sequenziale all'interno del nome.
L'azione può essere eseguita su SEG standalone e a livello di macchina all'interno di un cluster.
Passaggio 1. Accedere tramite CLI e digitare i comandi successivi logconfig > deletelogfile > Selezionare il numero che rappresenta la sottoscrizione del log > Selezionare il numero che rappresenta il log > Y per confermare.
Nota: l'azione di eliminazione è immediata e permanente e non richiede il commit delle modifiche.
