The Cisco ASA must be configured to use TCP when sending log records to the central audit server.

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.

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-239858r819136_chk)

Review the ASA configuration and verify it is configured to use TCP as shown in the example below. logging host NDM_INTERFACE 10.1.22.2 6/1514 logging permit-hostdown Note: The command "logging permit-hostdown" must also be configured to ensure that when either the syslog server is down or the log queue is full, new connections to ASA are allowed, to prevent an unintended denial of service. However, log records can be lost if the internal queue fills before restoring the connection to the log server. If the ASA is not configured to use TCP when sending log records to the central audit server, this is a finding.

Fix Text (F-43050r665859_fix)

Configure the ASA to use TCP when sending log records to the syslog server. ASA(config)# logging host NDM_INTERFACE 10.1.22.2 6/1514 ASA(config)# logging permit-hostdown
