Juniper ATP Cloud provides zero-day malware protection for non-Juniper firewalls. It's a cloud-based service that analyzes files and network traffic to detect and prevent known and unknown (zero-day) threats. It uses a combination of static and dynamic analysis techniques, as well as machine learning, to detect and block malicious files, even if they are not known to traditional anti-virus software. It also provides real-time visibility and detailed forensics for incident response and remediation.

To share threat intelligence from your environment with third party tools, you need to enable Juniper ATP Cloud to share threat intelligence and configure application tokens in the Juniper ATP Cloud to limit who has access. The other options are incorrect because:

• A. Configuring application tokens in the SRX Series firewalls is not necessary or sufficient to share threat intelligence with third party tools. Application tokens are used to authenticate and authorize requests to the Juniper ATP Cloud API, which can be used to perform various operations such as submitting files, querying C&C feeds, and managing allowlists and blocklists1. However, to share threat intelligence with third party tools, you need to enable the TAXII service in the Juniper ATP Cloud, which is a different protocol for exchanging threat information2.
• D. Enabling SRX Series firewalls to share threat intelligence with third party tools is not possible or supported. SRX Series firewalls can send potentially malicious objects and files to the Juniper ATP Cloud for analysis and receive threat intelligence from the Juniper ATP Cloud to block malicious traffic3. However, SRX Series firewalls cannot directly share threat intelligence with third party tools. You need to use the Juniper ATP Cloud as the intermediary for threat intelligence sharing.

Therefore, the correct answer is B and C. You need to enable Juniper ATP Cloud to share threat intelligence and configure application tokens in the Juniper ATP Cloud to limit who has access. To do so, you need to perform the following steps:

• Enable and configure the TAXII service in the Juniper ATP Cloud. TAXII (Trusted Automated eXchange of Indicator Information) is a protocol for communication over HTTPS of threat information between parties. STIX (Structured Threat Information eXpression) is a language used for reporting and sharing threat information using TAXII. Juniper ATP Cloud can contribute to STIX reports by sharing the threat intelligence it gathers from file scanning. Juniper ATP Cloud also uses threat information from STIX reports as well as other sources for threat prevention2. To enable and configure the TAXII service, you need to select Configure > Threat Intelligence Sharing in the Juniper ATP Cloud WebUI, move the knob to the right to Enable TAXII, and move the slidebar to designate a file sharing threshold2.
• Configure application tokens in the Juniper ATP Cloud. Application tokens are used to authenticate and authorize requests to the Juniper ATP Cloud API and the TAXII service. You can create and manage application tokens in the Juniper ATP Cloud WebUI by selecting Configure > Application Tokens. You can specify the name, description, expiration date, and permissions of each token. You can also revoke or delete tokens as needed. You can use the application tokens to limit who has access to your shared threat intelligence by granting or denying permissions to the TAXII service1.

The flow-session resource is needed in order to ensure adequate and secure communication between the two logical systems.

• The flow-session resource must be defined in the security profile for the interconnect logical system because the interconnect logical system is responsible for forwarding traffic between other logical systems. The flow-session resource determines the maximum number of sessions that the interconnect logical system can create and maintain. If the flow-session resource is not allocated or is insufficient, the interconnect logical system might drop packets or fail to establish sessions1.
• The NAT resources are not needed to be allocated to the interconnect logical system because the interconnect logical system does not perform any NAT operations on the traffic. The NAT resources are only relevant for the logical systems that need to translate the source or destination IP addresses or ports of the traffic1.
• No resources are not needed to be allocated to the interconnect logical system is incorrect because the interconnect logical system still requires some resources to function properly, such as the flow-session resource. The interconnect logical system cannot operate without any resources allocated to it1.
• The resources must be calculated based on the amount of traffic that will flow between the logical systems is partially correct, but not the best answer. The resources must be calculated based on the amount of traffic and the type of traffic that will flow between the logical systems. For example, the flow-session resource depends on the number and duration of sessions, the security-log-stream-number resource depends on the number and size of logs, and the NAT resource depends on the number and type of NAT rules1.

The exhibit shows the output of the show security intelligence category summary command on the SRX-1 device. This command displays the status of the security intelligence categories configured on the device. In the output, we can see that there are two categories configured - Proxy_Nodes and Proxy_Node3. The Proxy_Nodes category is a custom category that is created by the SRX-1 device using the adaptive threat profiling feature. The Proxy_Node3 category is a third-party category that is downloaded from the Juniper ATP Cloud service. The Proxy_Nodes category contains the IP addresses that match the security policy named Proxy-ATP on the SRX-1 device. The Proxy_Node3 category contains the IP addresses that are associated with the Tor network.

The two statements that are true based on the exhibit are:

• The SRX-1 device creates the Proxy_Nodes feed, so it cannot use it in another security policy. This is because the adaptive threat profiling feature does not allow the device that creates the feed to use it in another security policy. The feed is intended to be shared with other devices in the same realm through the Juniper ATP Cloud service. The SRX-1 device can only use the feeds that are created by other devices or downloaded from third-party sources.
• You can only use the Proxy_Node3 feed as the destination-address match criteria of another security policy on a different SRX Series device. This is because the Proxy_Node3 feed is a third-party feed that is downloaded from the Juniper ATP Cloud service. The SRX-1 device can use this feed as a dynamic address object in its security policies. However, the feed is configured with the destination-only option, which means that it can only be used as the destination-address match criteria of a security policy. The source-address match criteria of a security policy cannot use this feed.
