The SLES for vRealize must audit all account creations.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
|---|---|---|---|---|

| Description |
|---|
| Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply create a new account. Auditing of account creation mitigates this risk. To address access requirements, many operating systems may be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements. |
