Title

The Cisco ASA must be configured to off-load log records to a centralized log server. (Cat II impact)

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.

Check Content

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.
