Discussion

Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading ensures audit information does not get overwritten if the limited audit storage capacity is reached and also protects the audit record in case the system/component being audited is compromised. This also prevents the log records from being lost if the logs stored locally are accidentally or intentionally deleted, altered, or corrupted.

Verify that a syslog server has been defined.

Step 1: Navigate to Configuration >> ASA Firepower Configuration >> Policies > Actions Alerts. The Alerts page appears.

Step 2: Verify the IP address and port number of the syslog server.

If the Cisco ASA is not configured to send log records to a centralized log server, this is a finding.
