Ports Configuration
The ports configuration subsystem allows the ports of the system to be opened or closed based on the functionality and security needs of the user.
Each of these options is described as follows:
- No Security (Open All Ports): This option completely opens all of the ports of the system. It should be used only for debugging or in premises in which absolute security can be guaranteed. This is the default for the appliance since it is assumed the appliance will be protected via a premises-level firewall.
- Low Security: This option closes all ports except those associated with all system functionality.
- Medium Security: This option closes all ports except those associated with system functionality - and additionally closes those ports associated with system functionality that are most associated with potential attacks. This option should be used only if there are threats behind the firewall of the premises.
- High Security: This option closes almost all of the ports of the system except a very strict subset of the minimum ports that must be open for backup and vaulting to occur. It should only rarely be used and only in very special circumstances. Please note that the Unitrends Administrator Interface will not operate if high security is set.
