| 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 information system (e.g., module or policy filter). | ||||

1. Verify Nutanix AOS generates audit records when concurrent logons to the same account occur using the following command.
$ sudo grep dir /etc/security/faillock.conf
# The directory where the user files with the failure records are kept.
dir = /var/log/faillock
2. Using the location of the faillock log file, check that the following calls are being audited by performing the following command to check the file system rules in "/etc/audit/audit.rules".
$ sudo grep -w faillock /etc/audit/audit.rules
-w /var/log/faillock -p wa -k logins
If the commands do not return a line, or the lines are commented out, this is a finding.
