OT Security EM Overview

The Overview page features widgets that offer an at-a-glance view of your complete enterprise inventory and security posture. OT Security EM aggregates data from all sites and displays it in widgets. Along with the standard widgets for individual sites, the EM Overview page includes an ICP Status widget showing each site's the connectivity status.

To access the Overview page:

In the left hand navigation bar, click Overview.

The OT Security EM Overview page appears.

The Overview page includes the following widgets:

Widget	Description
Risk Score	The Average Risk Score is the average of all asset scores in your environment. To view a breakdown of the score, hover over the value. The Average Risk Score uses the following color codes to indicate the severity of the risk: Low (Green):0—29 Medium (Yellow): 30—69 High (Red): 70—100 OT Security calculates the asset scores based on the following factors that changes with time (decaying events, firmware, and state changes): Criticality - Based on the asset type and purdue level. For example, a PLC controls production, so it is considered critical, whereas a camera is typically less critical. Vulnerabilities - Based on the Vulnerability Priority Rating (VPR) asset. Events - Based on the events associated with the asset. Policies trigger events and each policy defines a severity. The severity is calculated based on the number of events, their severity, and how long they existed. Older events affect the score less than recent events. Backplane - An asset that resides on a backplace affects the scores of its neighbor assets. For example, if one module is vulnerable, the entire backplane is also vulnerable.

Assets and Vulnerabilities	The current state of assets and vulnerabilities in your environment. Includes separate widgets for each asset type (OT Controllers, Network Assets, IoT Assets) that show the number of assets in that category and the number of assets that are at high risk.
Status Report	The overall status of your environment, such as assets discovered, total events, number of high risk events, number of configuration events in the last 24 hours. The widget also shows the number of ICPs and sensors that are online. The widget also includes total events in the last 7 days and in the last one hour.
Assets by Type	The number of assets by type, such as endpoint, PLC, and OT device.
Assets by Criticality	The number of assets by their criticality: High, Medium, or Low.
Connected Sites	Lists the ICPs connected to the EM. The widget includes the following details: Name — The name of the ICP. Assets — The number of assets within the ICP. Average Risk Score — The average risk score of the ICP. Severe Vulnerability — The number of vulnerabilities in the critical state. Last 24h Events — The number of events recorded in the ICP in the last 24 hours. To open the ICPs page, in the upper-right corner, click ICPs Management.
