Firewall SRG:
SRG-NET-000098-FW-000021
(in versions v2 r3 through v1 r5)
Title
The firewall must be configured to use TCP when sending log records to the central audit server. (Cat II impact)
Discussion
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.
Check Content
Review the firewall configuration and verify that it is configure to use TCP. If the firewall is not configured to use TCP when sending log records to the central audit server, this is a finding.
Fix Text
Configure the firewall to use TCP when sending log records to the central audit server.
