The Cisco ASA must be configured to use TCP when sending log records to the central audit server.
An XCCDF Rule
Description
If the default UDP protocol is used for communication between the hosts and devices to the Central Log Server, then log records that do not reach the log server are not detected as a data loss. The use of TCP to transport log records to the log servers improves delivery reliability.
