Nutanix AOS must generate audit records when concurrent logons to the same account occur from different sources.


Overview

Finding ID Version Rule ID IA Controls Severity
V-254159 NUTX-OS-000560 SV-254159r991582_rule Medium
Description
Without generating audit records 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).
