SecIntel Feeds Overview and Benefits

SecIntel provides carefully curated and verified threat intelligence from Juniper ATP Cloud, Juniper Threat Labs, Dynamic Address Group (DAG), and industry-leading threat feeds to MX Series routers, SRX Series Firewalls, and NFX Series Network Services Platform to block Command and Control (C&C) communications at line rate. SecIntel delivers real-time threat intelligence by enabling automatic and responsive traffic filtering.

SecIntel integrates with EX Series and QFX Series switches and enables these switches to subscribe to SecIntel’s infected host feed. This enables you to block compromised hosts at the switch port. You can now extend SecIntel throughout your entire network and increase the number of security enforcement points.

Benefits of SecIntel Feeds

You can view all the default feeds that are available with your current license.

Using this page, you can enable the following feeds for integration with Juniper ATP Cloud.

• Juniper threat feeds

• Third party threat feeds—IP threat feeds and URL threat feeds.

• Dynamic address group feeds—Juniper DAG feeds and Third-party DAG feeds.

Note:

The expiry of the SecIntel feeds depends upon the time-to-live (TTL) value, which is different for each feed.

Note:

The total number of CC feeds are 32, out of which four feeds are reserved for cc_ip, cc_url, cc_ipv6, and cc_cert_sha1. So, you can enable up to 28 feeds to the CC category, which includes CC custom feeds and CC third-party feeds. This limit is applicable if you are injecting additional feeds using the available open API.

Information to know if you are enabling external feeds:

• If a hit is detected on an enabled external feed, this event appears under Monitor > Threat Sources with a threat level of 10.

• On enrolled SRX Series Firewalls, you can configure policies with the permit or block action for each feed. Note that C&C and Infected Host feeds require an enabled Security Intelligence policy on the SRX Series Firewall in order to work.

• External feeds are updated once every 24 hours.

Warning:

Understand that these are open source feeds managed by third parties and determining the accuracy of the feed is left up to the Juniper ATP Cloud administrator. Juniper will not investigate false positives generated by these feeds.

Warning:

Configured SRX Series policies will block malicious IP addresses based on enabled third party feeds, but these events do not affect host threat scores. Only events from Juniper ATP Cloud feeds affect host threat scores.

To enable the available feeds, do the following:

1. Navigate to Configure > Feeds Configuration > SecIntel Feeds.

2. For each feed, select the toggle button to enable the feed. Refer to the guidelines in Table 1.

   Note:

   The Infected Host feed is enabled for all license tiers. For licensing information about all other Juniper SecIntel feeds, see Software Licenses for ATP Cloud.

   Click the Go to feed site link to view feed information, including the contents of the feed.

   Note:

   • Starting in Junos OS Release 19.4R1, third party URL feeds are supported on Juniper ATP Cloud.

   • Since Ransomware Tracker and Malware Domain list are deprecated, ransomware tracker and malware domain list IP feeds are not supported on Juniper ATP Cloud. If you had enabled this feed earlier, you might stop receiving these feeds.

   • The update interval for a third party Internet service feed is one day.

3. Like other C&C and infected host feeds, enabled third party feeds require a security intelligence policy on the SRX Series Firewall in order to work. Example commands are provided here. See the Juniper Advanced Threat Prevention Cloud CLI Reference Guide for more information.

   • On the SRX Series Firewall: Configure a Security Intelligence Profile

     set services security-intelligence profile secintel_profile category CC

     set services security-intelligence profile secintel_profile rule secintel_rule match threat-level 10

     set services security-intelligence profile secintel_profile rule secintel_rule match threat-level 9

     set services security-intelligence profile secintel_profile rule secintel_rule then action block close

     set services security-intelligence profile secintel_profile rule secintel_rule then log

     set services security-intelligence profile secintel_profile default-rule then action permit

     set services security-intelligence profile secintel_profile default-rule then log

     set services security-intelligence profile ih_profile category Infected-Hosts

     set services security-intelligence profile ih_profile rule ih_rule match threat-level 10

     set services security-intelligence profile ih_profile rule ih_rule then action block close

     set services security-intelligence profile ih_profile rule ih_rule then log

     set services security-intelligence policy secintel_policy Infected-Hosts ih_profile

     set services security-intelligence policy secintel_policy CC secintel_profile

4. The security intelligence policy must also be added to an SRX Series Firewall policy.

   • On the SRX Series Firewall: Configure a Security Policy (Enter the following commands to create a security policy on the SRX Series Firewall for the inspection profiles.)

     set security policies from-zone trust to-zone untrust policy 1 match source-address any

     set security policies from-zone trust to-zone untrust policy 1 match destination-address any

     set security policies from-zone trust to-zone untrust policy 1 match application any

     set security policies from-zone trust to-zone untrust policy 1 then permit application-services ssl-proxy profile-name ssl-inspect-profile-dut

     set security policies from-zone trust to-zone untrust policy 1 then permit application-services security-intelligence-policy secintel_policy

   For more information on configuring the SRX Series with Juniper ATP Cloud using the available CLI commands, refer to the Juniper Advanced Threat Prevention Cloud CLI Reference Guide.

Using the office365 Feed

1. Enable theUsing the office365 Feed check box in Juniper ATP Cloud to push Microsoft Office 365 services endpoint information (IP addresses) to the SRX Series Firewall. The office365 feed works differently from other feeds on this page and requires certain configuration parameters, including a pre-defined name of “ipfilter_office365”.

2. After you enable the check box, you must create a dynamic address object on the SRX Series Firewall that refers to the ipfilter_office365 feed as follows:

   • set security dynamic-address address-name office365 profile category IPFilter feed ipfilter_office365

     Note:

     A security policy can then reference the dynamic address entry name (‘office365’ in this example) in the source or destination address.

   A sample security policy is as follows:

Use the following command to verify the office365 feed has been pushed to the SRX Series Firewall. (Update status should display Store succeeded.)

• show services security-intelligence category summary

Use the following command to show all the individual feeds under IPFILTER.

• show security dynamic-address category-name IPFilter
