Learn how Arc provides endpoint security in high availability environments.
Introduction
An overview of Arc.
Detection information
The information that Arc detects, listed for each operating system (OS). The table shows two types of Category: network and asset. When the Category is listed as network, it means that the detection is based on information that has been extracted from the network. When the Category is listed as asset, it means that the detection is based on information that has been extracted from the asset.
Arc Embedded detection information
Each Arc Embedded implementation inherits all the detected information from its architecture as shown in Detection information, and then adds vendor specific detections.

Learn how Arc provides endpoint security in high availability environments.
- Introduction
  An overview of Arc.
  - Arc
    Arc™ is a host-based sensor that detects and defends against malicious or compromised endpoints, and insider attacks. You can use Arc sensors to aggregate data for analysis and reports, either on-premises, or in the Vantage cloud.
  - Arc Embedded
    This version of Arc can be embedded directly on programmable logic controllers (PLCs).
  - Architecture
    It is important to understand the different architecture possibilities that are available with Arc.
  - Arc in Guardian
    The Arc button in the Guardian Web UI lets you access the different pages for Arc.
  - Arc in CMC
    The Arc button in the Central Management Console (CMC) Web UI lets you access the different pages for Arc.
  - Deployment
    The Deployment page shows a table of all the devices available for Arc deployment.
  - Deployment settings
    The Deployment settings page lets you configure the settings for your Arc deployment.
  - Node points
    The Node points page shows data points that are collected over time, and represent the state of the target machine.
  - Dependencies
    The Dependencies page shows the status of the dependencies. When a dependency is missing, you can use the upload icon in the Actions column to upload it.
  - Arc in Vantage
    The Sensors page shows all the Arc sensors in the network. It also lets you connect an Arc sensor.
  - Viewing data from Arc
    The data Arc acquires can be viewed in different places, and in different formats.
  - Commands syntax
    The example commands given in this documentation are for Microsoft Windows. Some of these commands are the same in other operating systems (OS), but when a procedure is specific to a different OS, the correct syntax for that OS is used.
  - Security measures
    A description of the security measures that Arc uses.
  - Detection information
    The information that Arc detects, listed for each operating system (OS). The table shows two types of Category: network and asset. When the Category is listed as network, it means that the detection is based on information that has been extracted from the network. When the Category is listed as asset, it means that the detection is based on information that has been extracted from the asset.
    - Arc Embedded detection information
      Each Arc Embedded implementation inherits all the detected information from its architecture as shown in Detection information, and then adds vendor specific detections.
- Requirements
  The machine and network requirements necessary to use Arc.
- Preparation
  Information on how to import Arc packages, and install a license.
- Configuration
  Details on how to configure Arc.
- Deployment
  Information on how to deploy Arc. This includes details for manual and automatic deployments, and deployment through a mobile device management (MDM) system.
- Execution
  Information on the different modes that you can use with Arc.
- Troubleshooting
  Troubleshooting procedures to help you solve problems that might occur when you use Arc.
- Print format documentation
  A list of all the print-format documentation that is available for Arc.

Arc Embedded detection information

Each Arc Embedded implementation inherits all the detected information from its architecture as shown in Detection information, and then adds vendor specific detections.

Table 1. Mitsubishi Electric
Operating System	Linux
Architecture	Arm
Prerequisites	Supported intelligent function module installed, with the correct Linux image. The default installed operating system (OS) is Gx Works.
Supported deployment modes	Deploy Arc automatically from Guardian
Supported deployment modes	Deploy Arc manually without a local UI
Supported execution modes	Service mode
Supported by	MELSEC iQ-R series with RD55UP12-V intelligent function module.
Additional information	Nodes aggregation, Hardware components / backplane information, local state (LED panel information, through alert type ID SIGN:DEV-STATE-CHANGE, SIGN:OT_DEVICE-START, SIGN:OT_DEVICE-STOP), disconnection of Ethernet cable (through SIGN:DEV-STATE-CHANGE), disconnection of module (through SIGN:DEV-STATE-CHANGE), program transfer (through SIGN:PROGRAM-TRANSFER), program change (through SIGN:PROGRAM-CHANGE).
Recommended configuration	The RD55UP12-V module has two network interfaces. Arc uses one of these to connect to the upstream. It is recommended to use the second network interface to monitor and have it connected to a switch SPAN port to get all the data from the central processing unit (CPU) module. Use in combination with Smart Polling's MELSOFT strategy for maximum visibility.
