The Nokia router must generate an immediate real-time alert for all audit failure events requiring real-time alerts.

Description
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less).

Verify the external syslog server is configured and online, as shown in the example below: - show log syslog # show log syslog Syslog Target Hosts Syslog Name Id Ip Address Port Sev Level Below Level Drop Facility Prefix TLS Profile 1 1 1.1.1.1 514 info 0 local7 yes Verify syslog operation by a configuration change and verify the syslog server has received the entry. If the syslog server does not receive the configuration change, this is a finding. If an immediate alert of all audit failure events requiring real-time alerts is not generated, this is a finding.

Fix Text (F-88247r1203375_fix)

Configure the Nokia router to generate an immediate real-time alert of all audit failure events requiring real-time alerts into a syslog server. Configure a log file: - exit all - configure log log-id <id> - from main, security, and change - to syslog <syslog id> Configure a syslog: - exit all - configure log syslog <syslog id> - address <syslog server ip address> - level info - log-prefix <log prefix to be shown in syslog server> - port <UDP port #> - timestamp-format millisecond Configure the syslog server to notify the appropriate personnel.
