Oracle Linux for MICROS Setup

The first time the device is booted, the Oracle Linux for MICROS setup process begins. This setup requires configuration information including Support user account name and network connection settings.

General guidance for Oracle Linux for MICROS:

• Creating a Support user account name and password. The Oracle Linux for MICROS installation process provides instructions for naming Support user accounts. For the Support user account password, use complex passwords.

• Selecting a network connection. Only connect to secure networks.

• Configure Network Settings. Oracle Linux for MICROS setup does not automatically name the device. Avoid choosing a computer name that leaks information about device. For example, Linux10POSTerminal2 allows an attacker with network access to immediately determine the operating system version and the purpose of the device.

Oracle Linux for MICROS provides firewall protection for both inbound and outbound traffic. Only select ports for transmitting data in/out are open; all other ports are closed.
