Clock security
The security of the 8000 clock relies heavily on the security of the network to which the clock is connected. If the 8000 is placed on a public network accessible by the Internet, you run the risk of unauthorized access.
Although the user account that accesses the 8000 (the root user) is password protected, we strongly recommend that the clock be placed on a secure network behind a firewall.
Also, to decrease the possibility of unauthorized access, change the default passwords for the root user. The default passwords may be guessed by malicious software. In addition, there is a daily password change process for the default root user if you apply patch D for the 8100 and 8200 Series clocks.
See Automated daily password change process for the default root password.
