What does the command 'show log security' display?

The command 'show log security' is used in Junos OS to display security-related log messages. This log includes important information regarding the operations of the security features within the device, such as firewall events, intrusion detection system (IDS) alerts, and other security incidents that have occurred. Analyzing these logs helps network administrators monitor unauthorized access attempts, track potential security breaches, and maintain compliance with security policies.

Traffic statistics, system error messages, and routing protocol updates are relevant to different aspects of the device's functioning but are not part of the output generated by this specific command. Traffic statistics would typically be viewed using commands associated with interfaces or monitoring features, system error messages are located in different system logs, and routing protocol updates would be queried through routing-related commands.
