Websense Protector

The Websense Data Security protector is a virtual machine that intercepts outbound HTTP traffic (posts) and analyzes it to prevent data loss and leaks of sensitive information over the web. The protector communicates with a dedicated Windows server for DLP policy information and can monitor or block data from being posted when a match is detected. Content analysis is performed on box, so no sensitive data leaves the protector during this process.

To use the protector’s data loss prevention (DLP) capabilities, you must purchase and install Websense Data Security, configure Web DLP policies in the Data Security manager, and perform initial setup through the Management Service.

Provisioning a Websense Protector Instance

The Websense© Protector requires a Data Security Management Server that must be configured outside the SDX appliance. Select exactly one management interface and two data interfaces. For the data interfaces, you must select Allow L2 Mode. Make sure that the Data Security Management Server can be accessed through the management network of the Websense protector. For the Name Server, type the IP address of the domain name server (DNS ) that will serve this protector.

Note: SR-IOV interfaces (1/x and 10/x) that are part of a channel do not appear in the list of interfaces because channels are not supported on a Websense protector instance.

You must download a protector image from the Websense website and upload it to the SDX appliance before you start provisioning the instance. For more information about downloading a protector image, see the Websense website . Make sure that you are using Management Service build 118.7 or later on the SDX appliance.

On the Configuration tab, navigate to Websense Protector > Software Images.

To modify the values of the parameters of a provisioned Websense protector instance, in the Websense Protector Instances pane, select the instance that you want to modify, and then click Modify. In the Modify Websense Protector wizard, set the parameters. Do not modify the interfaces that were selected at the time of provisioning a Websense instance. XVA file cannot be changed unless you delete the instance and provision a new one.

You can generate a tar archive for submission to technical support. For information about generating a technical support file, see Generating a Tar Archive for Technical Support.
