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 showing starting and ending time for administrator access to the system. 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 { any 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 { change-log info; interactive-commands info; structured-data; } file { any info; structured-data; } If the network device does not generate audit records showing starting and ending time for administrator access to the system, this is a finding.
