The aggregation of log data kept on a syslog server can be used to detect attacks and trigger an alert to the appropriate security personnel. The stored log data can be used to detect weaknesses in security that enable the network Information Assurance team to find and address these weaknesses before breaches can occur. Reviewing these logs, whether before or after a security breach, is important in showing whether someone is an internal employee or outside threat.
Verify the Nokia router is configured to send log data to at least two central log servers, as shown in the example below: - show log syslog Syslog Target Hosts Syslog Name Id Ip Address Port Sev Level Below Level Drop Facility Prefix TLS Profile Sunnyvale Server 1 10.1.1.2 514 emergency 0 local7 yes Naperville Server 2 192.168.0.10 514 info 0 local7 yes If the Nokia router is not configured to send log data to at least two central log servers, this is a finding.
Configure the Nokia router to send log data to at least two central log servers: - configure log syslog <syslog id> - address <syslog server ip address> - level <messages with severity level equal or higher to be reported- recommend warning> - prefix <prefix message that will show up for each log entry> - timestamp-format millisecond Configure the log file that will be off-loaded to the syslog server: - configure log log-id <log id> - from main change security - to syslog <syslog id>
