1 - Welcome to NetWitness Insight

NetWitness Insight is a SaaS solution available as an extension for a NetWitness Network, Detection & Response (NDR) customer. NetWitness Insight is an advanced analytics solution that leverages unsupervised machine learning to empower the response of the Security Operations Center (SOC) team. NetWitness Insight continuously examines network data collected by the Decoder to discover, profile, categorize, characterize, prioritize, and track all assets actively.

NetWitness Insight passively identifies all assets in the environment and alerts analysts of their presence. The discovered assets are automatically categorized into groups of similar servers and prioritized based on their network profiles. These assets are presented to analysts to guide them to focus on certain assets to protect their organization.

NetWitness Insight enables you to do the following:

• Asset discovery and characterization.
• Monitor critical Assets.
• Leverage the security operations team to triage based on prioritization.

2 - NetWitness Insight Use Cases

NetWitness Insight provides advanced analytics capabilities to alert organizations about risky and anomalous assets.

Analysts must scan through billions of network sessions and IP addresses to protect their organization, searching for threats and anomalies. This is where NetWitness Insight passively identifies the assets in the enterprise to alert analysts of their presence. The discovered assets are automatically categorized into groups of similar servers and prioritized based on their network profiles. These assets are presented to analysts to guide them to focus on specific assets to protect their organization.

Use Cases

The following are typical use cases for NetWitness Insight:

• Provides asset discovery and characterization.
• Provides asset exposure rank.
• Provides efficiency in security operations through triage based on prioritization.

3 - NetWitness Insight Architecture

NetWitness Insight enables analysts to get complete visibility into unknown assets and can help increase the visibility of the assets within the organization.

NetWitness Insight uses custom machine learning to process the data. The Insight Sensor collects the network metadata from the Packet Decoder and transfers metadata to the NetWitness Cloud every hour. The NetWitness Cloud merges all the network metadata received from different Insight sensors in a customer environment and provides a unified view of their network to the analysts for analysis in the Springboard assets panel view.

The Springboard assets panel queries the Cloud Connector Sensor for asset data. Cloud Connector Sensor retrieves asset data from the NetWitness Cloud and transfers it to Springboard. This helps analysts to drill down the assets data for further investigation and take immediate action.

NetWitness Insight uses unsupervised learning techniques applied to traffic associated with the assets to determine the type and significance of the asset. The services, clients, and external clients are the parameters aggregated to determine the total traffic of an asset. NetWitness Insight also computes custom importance ranks reflecting asset exposure and activity ranks so that security teams can use them to prioritize and triage incidents.

11 - Planning Requirements

Before you install the sensors, you must plan for the following:

• The NetWitness Platform (Admin Server and Packet Decoder Host) is on version 12.3 or later.

• Customers must have NetWitness Cloud tenant account with entitlements that allow NetWitness Insight capability.

• Ensure you have the administrator access to the NetWitness Cloud Portal.

• The host on which the Insight Sensor and Cloud Connector Sensor will be installed needs to be connected to Amazon Web Services(AWS). This might require changes to your existing firewall rules. Hosts will need to connect to the IP ranges for the chosen deployment region. For more information on the current list of AWS IPs by region, see AWS IP address ranges.

• If a proxy is identified as either the source or destination of network connections, it can limit the effectiveness of NetWitness Insight, whether it’s North-South (outbound) or East-West (lateral) traffic.

  • When a proxy is used as the source of a connection, all internal assets will appear to have the same IP addresses, as all connections are considered to originate from the same source. This can make it difficult to track the true source of connections and obtain accurate ranks, types, and categorizations.

  • When a proxy is used as the destination of a connection, all the connections will appear to be going toward the same destination. This can also cause difficulties in obtaining accurate ranks, types, and categorizations.

• To classify assets effectively, you must decrypt the network traffic. Encrypted traffic is captured as an SSL category and hence, Insight does not have complete visibility in the data.

• For organizations that do not follow RFC 1918 for private IP addresses, you must configure the Traffic Flow LUA parser to tag the Decoder traffic correctly. For more information on configuration, see the topic Traffic Flow LUA Parser.

• Ensure that the analysts have write (manage) access to create the Springboard panel. For more information, see the Springboard section in the Role Permissions topic in the System Security and User Management Guide.

• Ensure that the system clock is accurate. To fix the system clock, configure the NTP server on the Admin server. For more information on how to configure NTP server, see Configure NTP Servers.

You can install Insight Sensor on the following hosts:
