Local Settings

You can use the Local Settings to view and configure the OT Security EM settings. The Local Settings section includes these pages for configuring your settings:

The page allows you to view and edit device details and network information such as port configuration and system time, automatic logout (inactivity timeout).

The Device page shows the following information:

Parameter Description
Device Name The name of the OT Security management system.
Device URL The URL used to access the OT Security EM console in a DNS environment.
System Time The date and time in the system. You can use an NTP server to synchronize the system time with other assets in the network.
Timezone The time zone of the system.
DNS Servers You can enter the IPs of one or more DNS servers used in the network. This helps OT Security to identify DNS names of assets in the network.
Automatic Logout The period of inactivity that causes the system to log out automatically.
Ping Requests Set to detect whether or not the OT Security platform responds to ping requests.

The Port Configuration page shows details of the configured ports on the device. For more information on Port Configuration, see Port Configuration in the Tenable OT Security User Guide.

On the Certificate page, you can view information about your HTTPS certificate and generate a new certificate for secure HTTPS connections for the OT Security EM. Generating a new certificate overrides the current certificate. A certificate is valid for one year.

The Certificates page shows the following details:

Parameter Description
Issued to The entity to which the certificate was issued.
Issued by The entity that issued the certificate.
Issued on The issue date of the certificate.
Expires on The date when the certificate ages out.
