Discussion

Centralized management of user accounts and authentication increases the administrative access to the router. This control is particularly important protection against the insider threat. With robust centralized management, audit records for administrator account access to the organization's network devices can be more readily analyzed for trends and anomalies. The alternative method of defining administrator accounts on each device exposes the device configuration to remote access authentication attacks and system administrators with multiple authenticators for each network device.

Review the router configuration to verify that the device is configured to use at least two authentication servers as primary source for authentication as shown in the following example:

system {
    authentication-order radius;
    }
    radius-server {
        x.x.x.x secret "$8$xYW-dsq.5zF/wYnC"; ## SECRET-DATA
    }
    radius-server {
        x.x.x.x secret "$8$xYW-dsq.5zF/wYnC"; ## SECRET-DATA
    }

If the router is not configured to use at least two authentication servers for the purpose of authenticating users prior to granting administrative access, this is a finding.
