Description
Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the network device (e.g., module or policy filter).

Determine if the network device generates audit records when successful/unsuccessful logon attempts occur. Junos logs all logon attempts via the "authorization" syslog facility (or facility "any"). Verify logging level "any info" or "authorization info" is configured. [edit system syslog] file { authorization info; } host { 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 { authorization info; structured-data; } file { any info; structured-data; } If it does not generate audit records when successful/unsuccessful logon attempts occur, this is a finding.
