System security is handled through the AAA (Authentication, Authorization, and Accounting) mechanism that manages user access rights, privileges, and management methods. AAA uses both local and remote user databases. Data encryption is handled through the SSH mechanism.
The system is delivered with no default password configured; all passwords are user-defined. If a user-defined password is lost, a password recovery procedure can be invoked from the Startup menu. The procedure is applicable for the local terminal only and allows a one-time access to the device from the local terminal with no password entered.
Configuring Security Passwords
The security passwords can be configured for the following services:
Console
Telnet
SSH
HTTP
HTTPS
NOTE: Passwords are user-defined.
NOTE: When creating a user name, the default priority is "1," which allows access but not configuration rights. A priority of "15" must be set to enable access and configuration rights to the device. Although user names can be assigned privilege level 15 without a password, it is recommended to always assign a password. If there is no specified password, privileged users can access the Web interface with any password.
