Fix Recommendation

Configure the network device to generate audit records when concurrent logons from different workstations occur.

set system syslog file <file name> any info
set system syslog host <external syslog address> any info
set system syslog time-format year

Check Contents

Determine if the network device generates audit records when concurrent logons from different workstations occur.

Junos logs all logon attempts via the "authorization" syslog facility. Verify logging level "any info" or "authorization info" is configured. Time stamps are created for every log entry, both successful and failed logon attempts, and logout.

[edit system syslog]
file <file name> {
any info;
}
host <external syslog address> {
any info;
}
time-format year millisecond;

Syslog outputs in standard format unless the "structured-data" directive is configured. Verify the "structured-data" command for all files and external syslog servers requiring that format. For example:

[edit system syslog]
host <syslog address> {
change-log info;
interactive-commands info;
structured-data;
}
file <file name> {
any info;
structured-data;
}

If the network device does not generate audit records when concurrent logons from different workstations occur, this is a finding.
