IntroductionOverviewUse this guide to configure Stealthwatch and AnyConnect Secure Mobility Client NetworkVisibility Module (NVM) to allow:

l Storage of AnyConnect NVM fields

l Viewing the NVM fields

l Existing policy violation rules to trigger from NVM flows

Datagram Transport Layer Security (DTLS) is not supported.

Enhancements in Stealthwatch v7.3.2Endpoint Concentrator RemovalStarting in v7.3.2, the Endpoint Concentrator is not needed for the Endpoint Licensedeployment, and the Flow Collector has been enhanced to process Network Visibility Module(NVM) data on all Stealthwatch deployments, including Data Store.

Due to this enhancement, the Endpoint Concentrator is not supported in v7.3.2.

Endpoint License CapabilitiesEndpoint License, which is now supported for Data Store, provides:

l Full visibility to the endpoint, including on-network and off-network data

l Visibility to any NVM fields from the Endpoint Traffic (NVM) report in the Report Builderapp

l A minimum of 30 days of storage of NVM data

l Improved processing and query performance

The following table provides performance estimates for a standard enterprise traffic profile(most customers):

Flows per second (FPS) Number ofFC 4210s

Number ofDS 6200s/ 31 Days

StorageNetFlow NVM

300,000 150,000 1 3

There are several factors that may affect your specific performance, such as numberof hosts, average size of flows, and more. While we do our best to represent the dataas fairly and accurately as possible, your environment may experience differentlimits.

Upgrading from 7.3.1 to 7.3.2If you are an existing Stealthwatch customer upgrading from 7.3.1 to 7.3.2, you will need toremove the Endpoint Concentrator and reconfigure your NVM deployment.

Remove your Endpoint Concentrator(s) and configure your Flow Collector using the followinginstructions:

1. Remove your Endpoint Concentrator(s) from your cluster using Central Management.

a. Open Central Management.

b. On the Appliance Manager page, click the (Ellipsis) icon in the Actionscolumn for the Endpoint Concentrator.

c. Select Remove This Appliance, then click Yes.

2. Configure flows from the NVM client to the Flow Collector using the ConfigureNVM profile on AnyConnect Secure Mobility Client section.

3. Update your cluster to v7.3.2 using the Stealthwatch Update Guide (v7.2.1 and v7.3.x tov7.3.2).

4. Add the NVM processing port to your Flow Collector Advanced Settings using theConfigure the Flow Collector section.

5. Verify NVM data is processed using the Report Builder app or Flow Search using theVerification section.

For assistance, please contact Cisco Stealthwatch Support.

ConfigurationConfigure NVM profile on AnyConnect Secure Mobility Client

The AnyConnect Profile Editor is available through Cisco Adaptive Security DeviceManager (ASDM) or as a standalone offering. For more information about how to usethe AnyConnect Profile Editor, refer to the AnyConnect Administrator Guide.

1. Verify you have installed the Network Visibility Module.

2. Open the Network Visibility Module Profile Editor.

3. In the Collector Configuration section, enter the IP Address and Port of your FlowCollector.

We recommend you use port 2030 rather than the default port, 2055. If port 2030 isalready in use, you may use any non-reserved port. Do not use ports 2055, 514, or8514. You will use this port in step 5 of the Configure the Flow Collector section.

Configure the Flow Collector for Off-Network Cached Flows(optional)Use the following instructions to configure cache flow processing for collecting off-networkNVM data.

Collecting off-network NVM data impacts system performance. Do not enable thisconfiguration if you do not need to collect or analyze this data.

If you enable the configuration and your system performance is impacted, adjust thethrottle rate (refer to the AnyConnect Administator Guide) and/or decrease the nvm_age_limit_days (refer to the instructions in this section).

1. Before you start this procedure, make sure you finish the previous procedures. You willcontinue this configuration in the Flow Collector engine Support > Advanced Settings.If the Flow Collector is closed, log in to it directly, or:

l Log in to your SMC.

l From the navigation menu, click the (Global Settings) icon and select CentralManagement.

l Click the (Ellipsis) icon for your Flow Collector, then click View ApplianceStatistics. The Flow Collector Admin interface opens.

l Click Support > Advanced Settings.

2. Update the following fields:

l process_old_nvm_flows: Enter 1 to enable cached flows.

l nvm_age_limit_days: Enter the maximum number of days to collect cachedflows.For example, if you enter 7, it collects the last 7 days. If you enter 0 (zero), there isno limit. For best performance, set a limited number of days.

If a field is not shown, scroll to the bottom of the page. Click the Add New Optionfield. For more information about editing advanced settings on the Flow Collector,refer to the Advanced Settings online help topic.
