The Juniper router must be configured to use an authentication server for the purpose of authenticating users prior to granting administrative access.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-91189	JUNI-ND-001360	SV-101289r1_rule		High

Description
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.

Check Text ( C-90343r2_chk )
Review the router configuration to verify that the device is configured to use an authentication server 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 } If the router is not configured to use an authentication server for the purpose of authenticating users prior to granting administrative access, this is a finding.

If the router is not configured to use an authentication server for the purpose of authenticating users prior to granting administrative access, this is a finding.

Fix Text (F-97387r2_fix)
Step 1: Configure the authentication server as shown in the following example: [edit system] set radius-server x.x.x.x secret xxxxxxxxx Step 2: Configure the authentication order to use the authentication server as primary source for authentication as shown in the following example: set authentication-order radius Note: If there is no response from the authentication server, JUNOS will authenticate using a local account as last resort. It is recommended to not configure password at the end of the authentication order, as JUNOS will attempt to authenticate using a local account upon a rejection from the authentication server.
