Glossary

Terms used in this guide to define Lighthouse elements and concepts are listed below.

Term	Definition
AUTHDOWNLOCAL (RADIUS/LDAP/TACAS)	When AUTHDOWNLOCAL authentication option is selected, if remote authentication fails because the user does not exist on the remote AAA server, the user is denied access.
AUTHLOCAL (RADIUS/LDAP/TACAS)	When AUTHLOCAL authentication option is selected, if remote authentication fails because the user does not exist on the remote AAA server, Lighthouse tries to authenticate the user using a local account.
CELLULAR HEALTH	Status of the cellular connection of a node.
DARK MODE	Changes the user interface to display mostly dark colors, reducing the light emitted by device screens.
DOCKER	An open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. Docker powers the NetOps platform within the Lighthouse product.
ENROLLMENT	Connecting a node to Lighthouse.
ENROLLMENT BUNDLE	Used to assign a number of tags to a set of nodes when they are enrolled. During Enrollment, the bundle is specified using its name, and a bundle-specific Enrollment token.
ENROLLED NODE	A Node that has been connected to Lighthouse and is ready for use.
ENROLLMENT TOKEN	A password that authorizes the node with Lighthouse. Used when performing Node-based, or ZTP Enrollment.
INSTANCE	A single running Lighthouse.
INTRUSION DETECTION SYSTEM	An Intrusion Detection System (IDS) is a network security technology built for detecting vulnerability exploits against a target application.
LIGHT MODE	Changes the user interface to display mostly light colors. This is the default UI setting.
LIGHTHOUSE	System for accessing, managing and monitoring Opengear console servers.
LIGHTHOUSE ENTERPRISE	Offers an elevated centralized management solution with additional functionality. It supports growing trends such as edge computing and SD-WAN with High Availability and Remote IP Access.
LIGHTHOUSE VPN	The OpenVPN based connections that the Lighthouse instance has with the nodes it is managing
LOCALAUTH (RADIUS/LDAP/AAA)	When LOCALAUTH authentication option is selected, if local authentication fails, Lighthouse tries to authenticate the user using a remote AAA server.
MANAGED DEVICE	A device that is managed via a node through a serial, USB, or network connection.
MULTIPLE INSTANCE	Access nodes through multiple Lighthouse instances at the same time.
NODE	A device that can be enrolled with Lighthouse, allowing it to be accessed, managed, and monitored. Currently, Opengear console servers are supported on a standard license, with support for other vendors Console Servers available as an add-on.
PASSWORD POLICY	Administrative users can define rules for Lighthouse user passwords including length, types of characters, reuse, and expiration period.
PENDING NODE	A node that has been connected to Lighthouse and has been configured with a VPN Tunnel, but which has not yet been approved for access, monitoring, or management. The approval operation can be automated by configuring Lighthouse to auto- approve nodes.
PRIMARY INSTANCE	The main instance of Lighthouse used for updating configuration and node enrollment.
REMOTE LOGGING/REMOTE SYSLOG	The ability to send logs to a remote server, for the offsite storage and review of logs.
REPLICATION	Automatic copying of the primary Lighthouse database to any connected dependent instances. Replication ensures that these instances mirror the same information and maintains connections to the same nodes.
ROLE	A set of access rights for a particular group. Three roles are defined within Lighthouse: Lighthouse Administrator, Node Administrator, and Node User.
SECONDARY/DEPENDENT INSTANCES	Redundant instances of Lighthouse that are used to access Lighthouse information and connected nodes.
SMART GROUP	Dynamic filter used to search for particular nodes, or for defining the access rights of a group of users. Smart Groups use node properties, as well as tags defined by users.
TAG	User-defined attribute and value that is assigned to one or more nodes or ports. Tags are used when creating Smart Groups for filtering views or access to nodes and ports.
