Riverbed Optimization System (RiOS) must employ automated mechanisms to centrally manage authentication settings.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-62943	RICX-DM-000092	SV-77433r1_rule		Medium

Description
The use of authentication servers or other centralized management servers for providing centralized authentication services is required for network device management. Maintaining local administrator accounts for daily usage on each network device without centralized management is not scalable or feasible. Without centralized management, it is likely that credentials for some network devices will be forgotten, leading to delays in administration, which itself leads to delays in remediating production problems and in addressing compromises in a timely fashion.
