NET1021 - The network element must log all messages except debugging- 'Logging on'
The network device must log all messages except debugging and send all log data to a syslog server. Logging is a critical part of router security. Maintaining an audit trail of system activity logs (syslog) can help identify configuration errors, understand past intrusions, troubleshoot service disruptions, and react to probes and scans of the network. Syslog levels 0-6 are the levels required to collect the necessary information to help in the recovery process.
Configure the network device to log all messages except debugging and send all log data to a syslog server.
