Security
NOTE: Security functions not supported in EDS-400A series.
Security can be categorized in two levels: the user name/password level, and the port access level. For user
name/password level security, Moxa switches provide two different user login options: Terminal Access
Controller Access-Control System Plus (TACACS+) and Remote Authentication Dial In User Service (RADIUS).
The TACACS+ and RADIUS mechanism is a centralized “AAA” (Authentication, Authorization and Accounting)
system for connecting to network services. The fundamental purpose of both TACACS+ and RADIUS is to
provide an efficient and secure mechanism for user account management.
