To mitigate DNS data exfiltration, Infoblox Threat Insight (also referred to as Threat Analytics in the Infoblox GUI or Grid Manager) employs analytics algorithms to detect DNS tunneling traffic by analyzing incoming DNS queries and responses. These algorithms are developed through an extensive study and analysis of sample DNS statistics within which DNS tunneling data is identified by algorithms that cannot be detected by normal rules and signatures. For more information about DNS data exfiltration, see AboutDataExfiltration.

Infoblox Threat Insight identifies data exfiltration tunnels that bypass typical firewall systems. Some popular tunneling tools are OyzmanDNS, SplitBrain, Iodine, DNS2TCP, TCP-Over-DNS, and others. These types of DNS threats are identified as having high activities by using the TXT records in DNS queries. Infoblox Threat Insight also identifies tunnels that are used for C&C. These threats typically do not exhibit high activities or payloads. In general, NXDOMAIN responses fall into this category of threats.

You must have at least one RPZ license installed in your Grid (it can be installed on any Grid member) and the Threat AnalyticsInsight license installed on the Grid member on which you want to start the threat analytics insight service. To download updates for threat analytics insight module and whitelist allowlist sets, you must have at least one Threat AnalyticsInsight license installed in the Grid. When you enable the threat analytics insight service, NIOS starts analyzing incoming DNS data and applying these algorithms to detect security threats that have the same or similar behavior as the known data. Once security threats are detected, NIOS blacklists blocklists the domains and transfers them to the designated mitigation RPZ (Response Policy Zone), and traffic from the offending domains is blocked and no DNS lookups are allowed for these domains from NIOS members on which RPZ are assigned to them. The appliance also sends an SNMP trap each time it detects a new blacklisted blocklisted domain.

Infoblox Threat Insight also includes a whitelist allowlist that contains trusted domains on which NIOS allows DNS traffic. These are known good domains that carry legitimate DNS tunneling traffic such as Avast, Sophos, McAfee, Boingo, Barracuda, and others. The whitelist allowlist is extensible so new whitelisted allowlisted domains can be added and rolled out accordingly. For Threat Insight running on an On-Prem Infoblox DDI appliances, internal governance and vetting applied by Infoblox ensures all whitelist allowlist entries are accurate and curated, and contain only valid entries.

You can also add custom whitelisted allowlisted domains or move blacklisted blocklisted domains to the whitelistallowlist. For more information about how to configure Infoblox Threat Insight, see Configuring Infoblox Threat Insight below. Before you utilize Infoblox Threat Insight, there are a few guidelines you might need to consider. For more information about Guidelines for Using Infoblox Threat Insight, see below.

Infoblox Threat Insight came installed with a module set and a whitelist allowlist set. To receive subsequent module set and whitelist allowlist set updates, you can configure the appliance to automatically download and apply the updates for you, or you can manually upload the updates when the appliance displays a banner message notifying about available updates. For information about how to configure the update policy, see Defining the Threat Analytics Insight Update Policy below.

Licensing Requirements and Admin Permissions

...

Infoblox Threat Insight

To start the threat analytics insight service, you must have at least one RPZ license installed in your Grid (it can be installed on any Grid member) and the ThreatAnalyticsInsightlicense installed on the Grid member on which you want to start the threat analytics insight service. To download updates for threat analytics insight module and whitelist allowlist sets, you must have at least one ThreatAnalytics Insight license installed in the Grid.

Note that running the threat analytics insight service might affect your system performance if the appliance has a small capacity and is taking on heavy traffic. Evaluate your Grid and Grid members to ensure that you select an appliance that is appropriate for running the threat analytics insight service. For more information about  supported appliances, see Supported Appliances for Infoblox Threat Insight below.

Guidelines for Using Infoblox Threat Insight

Following are some guidelines to take into consideration when using Infoblox Threat Insight:

• To start the threat analytics insight service, you must have at least one RPZ license installed in your Grid (it can be installed on any Grid member) and the ThreatAnalyticsInsight license installed on the Grid member on which you want to start the threat analytics insight service. To download updates for threat analytics insight module and whitelist allowlist sets, you must have at least one Threat Analytics threat insight license installed in the Grid.

• Infoblox recommends that you run the threat analytics insight service for a limited time to monitor and preview what has been detected before actually blocking blacklisted blocklisted domains. You can carefully review the list of detected domains and decide which domains you want to continue blocking and which domains you want to add to the analytics whitelistinsight allowlist. You should review the blacklisted blocklisted domains on a regular basis to make sure that no legitimate use of DNS tunneling is blocked. Note that you can update the analytics whitelist insight allowlist by adding new whitelisted allowlisted domains, moving legitimate domains from the blacklisted blocklisted domain list, or using CVS import and export. For more information about Configuring a Local RPZ as the Mitigation Blacklist Blocklist Feed, see below.

• Analytics whitelisted Insight allowlist domains and supported DNS tunneling tools are updated periodically and are bundled with future NIOS releases. To ensure that your appliance is using the most up-to-date whitelistallowlist, upgrade to the next NIOS release or configure the appliance to download threat analytics insight updates. For information about upgrades, see Upgrading NIOS Software. Note that this process may change in future NIOS releases.

• There are no configurable parameters for Infoblox Threat Insight. Infoblox uses the build-in algorithms to analyze DNS statistics and blocks offending domains based on the analyzed data.

• DNS tunneling detection is not instantaneous. It may take a few seconds to a few minutes for the analytics insight to determine positive DNS tunneling activities.

• During an HA failover, analytics insight data that is in progress on the active node might be lost. Only new DNS queries on the new active node after a successful failover are being analyzed. It may take a few minutes for the analytics insight to reach its normal state. If there is no connection between the Grid Master and Grid member, blacklisted blocklisted domains detected by the analytics insight cannot be transferred to the Grid Master as RPZ records for a pre-configured RPZ zone — this is not applicable to standalone appliances with RPZ license installed. In addition, ensure that the passive node must also have the RPZ license installed and that its hardware model is capable of running the threat analytics insight service. For information about supported appliance models, see Supported Appliances for Infoblox Threat Insight below.

• The threat analytics insight service only works on recursive DNS servers and forwarding servers that use BIND as the DNS resolver. It does not support Unbound as the DNS resolver.

• The analytics whitelist insight allowlist only applies to Infoblox Threat Insight; it does not apply to signature-based tunneling detection. Anti-DNS tunneling threat protection rules are implemented to address signature-based tunneling analysis. For detailed information about threat protection rules, refer to the Infoblox Threat Protection Rules available on the Support web site.

• Infoblox Threat Insight does not support RESTful APIs.

...

Due to memory and capacity required to perform analyticsinsight, ensure that you install the Threat Analytics Insight and RPZ licenses, and enable the threat analytics insight service on an appliance that has a big enough capacity. Following are the supported Infoblox appliance models on which you can run the threat analytics insight service:

• PT-1405, and PT-2205.

• IB-4015, and IB-4030-10GE.

• TE-1415, TE-1425, TE-2215, and TE-2225.

• TE-V1415, TE-V1425, TE-V2215, TE-V2225, TE-V4010, and TE-V4015.

...

You must have at least one RPZ license installed in your Grid (it can be installed on any Grid member) and the Threat Analytics Insight license installed on the Grid member on which you want to start the threat analytics insight service. You must also create a new RPZ and use it as the designated mitigation blacklist blocklist feed so the appliance can transfer all blacklisted blocklisted domains to this feed.

NIOS continuously collects and analyzes statistics of incoming queries and responses, detects possible DNS tunneling activities, blocks offending domains that match the known data, and updates the mitigation blacklist blocklist feed (a designated local RPZ) of any known malicious domains. For supported appliance models for Infoblox Threat Insight, see Supported Appliances for Infoblox Threat Insight.

• Manually add a custom domain to the analytics whitelistinsight allowlist, as described in Adding Custom Whitelisted Allowlisted Domains below.

• Review the blacklisted blocklisted domains and make decisions about whether to move them to the analytics whitelist insiight allowlist so future DNS activities will not be blocked. For more information, see Viewing Blacklisted Blocklisted Domains below.

• Move a blacklisted blocklisted domain to the analytics whitelistinsight allowlist, as described in Moving Blacklisted Blocklisted Domains to the WhitelistAllowlist.

• Monitor DNS tunneling activities and events using pre-defined reports and the syslog, as described in Monitoring DNS Tunneling Activities below.

Starting and Stopping the Threat

...

Insight Service

To start the threat analytics insight service, you must have at least one RPZ license installed in your Grid (it can be installed on any Grid member) and the Threat Analytics Insight license installed on the Grid member on which you want to start the threat analytics insight service. You can also stop the service when necessary.

To start or stop the threat analytics insight service:

Configuring a Local RPZ as the Mitigation

...

Blocklist Feed

For the threat analytics insight service to function properly and for NIOS to properly report detected backlisted domains, you must create and designate local RPZs as the mitigation for the Grid. You can add any Response Policy Zones to the list of RPZs from different Network and DNS Views. When a domain is detected as malicious, NIOS will update all RPZs in the list. If you assign an existing RPZ that is used for other purposes as the mitigation blacklist blocklist feed, you may experience the following:

• Existing RPZ hits are reported as hits detected by the analytics insight after an upgrade.

• If you manually add rules to the RPZ, all RPZ hits are reported as hits detected by the analyticsinsight, regardless of whether they match the manually created rules or are detected through the threat analytics insight service.

Infoblox recommends that you run the threat analytics insight service for a limited time to monitor and preview what has been detected before actually blocking domains. To do so, set PolicyOverride to LogOnly(Disabled) when you create the RPZ so you can monitor blacklisted blocklisted domains without actually blocking them.

To create and designate a local RPZ as the blacklist blocklist feed:

1. Create a local RPZ by completing the procedure described in Configuring Local RPZs.

Updating Threat

...

Insight Module and

...

Allowlist Sets

Infoblox periodically releases threat analytics insight module and whitelist allowlist sets. To ensure that you can import threat analytics insight updates, you must have at least one Threat Analytics Insight license installed in the Grid. The threat analytics insight module set consists of the analytics insight application .jar file, which delivers changes and updates for DNS tunneling detection; and the whitelist allowlist set consists of updated trusted domains that carry legitimate DNS tunneling traffic. You can download updates for the module set and whitelist allowlist set independently depending on how often Infoblox rolls them out. The appliance displays the version numbers of the module set and whitelist allowlist set that your Grid is currently using. To view this information before downloading updates, see Viewing Module and Whitelist Allowlist Versions below.

You can configure the appliance to automatically receive and apply the latest module set and/or whitelist allowlist set. When you define an automatic update policy, the appliance checks both the analytics insight module and whitelist allowlist files and automatically downloads the files that have changed. You can also configure a manual update policy in which the appliance notifies you through the message banner when there are updates available. You can then decide whether you want to apply the updates to your Grid or not. For information about how to define the update policy, see Defining the Threat Analytics Insight Update Policy below. For information about how to perform manual updates, see Manually Uploading Uploading Threat Analytics Insight Updates below.

Infoblox recommends that you configure the appliance to automatically receive module and whitelist allowlist updates, so your appliance receives the latest information periodically. If you prefer to manually upload updates to your Grid, ensure that you apply them frequently to receive the most updated information.
