Discussion

Centralized management of authentication settings increases the security of remote and nonlocal access methods. This control is a particularly important protection against the insider threat. Audit records for administrator accounts 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. The Juniper SRX supports three methods of user authentication: local password authentication, Remote Authentication Dial-In User Service (RADIUS), and Terminal Access Controller Access Control System Plus (TACACS+). RADIUS and TACACS+ are remote access methods used for management of the Juniper SRX. The local password method will be configured for use only for the account of last resort; however, it will not be used for remote and nonlocal access or this will result in a CAT 1 finding (CCI-000765). This requirement references identification and authentication and does not prevent the configuration of privileges using the remote template account (CCI-000213).

Verify the Juniper SRX is configured to forward logon requests to a RADIUS or TACACS+. 

From the CLI operational mode enter: 
show system radius-server 
or 
show system tacplus-server

If the Juniper SRX is not configured to use at least one RADIUS or TACACS+ server, this is a finding.
