The Arista Multilayer Switch must automatically audit account creation.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-60835	AMLS-NM-000120	SV-75291r1_rule		Medium

Description
Upon gaining access to a network device, an attacker will often first attempt to create a persistent method of reestablishing access. One way to accomplish this is to create a new account. Notification of account creation helps to mitigate this risk. Auditing account creation provides the necessary reconciliation that account management procedures are being followed. Without this audit trail, personnel without the proper authorization may gain access to critical network nodes.
