Pearson JN0-335 New Attempt

Encrypted Traffic Insights is a feature of Juniper ATP Cloud and SRX Series firewalls that can detect malicious threats that are hidden in encrypted traffic without intercepting and decrypting the traffic. It permits organizations greater visibility and policy control over encrypted traffic, without requiring resource-intensive SSL Decryption1.

Encrypted Traffic Insights assesses the threat of the traffic by using two methods:

• It validates the certificates used by the external servers that the internal hosts are trying to connect to. It compares the certificate signatures with a blocklist of known malicious certificates and also checks the certificate validity, issuer, and subject. If the certificate is invalid or matches a malicious signature, the connection is blocked or alerted2.
• It reviews the timing and frequency of the connections to the external servers. It uses behavior analysis and machine learning to identify patterns and anomalies that indicate malicious activity, such as command and control (C&C) communications, botnet traffic, or data exfiltration. It also uses threat intelligence feeds to enrich the analysis and provide additional context2.

Encrypted Traffic Insights does not decrypt the file or the data in a sandbox or to validate the hash, as these methods would require breaking the encryption of the traffic, which would violate data privacy laws and introduce latency and performance issues21. References:

https://www.juniper.net/documentation/us/en/software/junos/security-iot/topics/topic-map/security-iot-overview.html SRX does not identify the iot device. It streams the metadata to Juniper ATP cloud and Junipe ATP cloud identifies the device.

 To create a security policy that will automatically add infected hosts to the infected hosts feed and block further communication through the SRX Series device, you need to add a security intelligence policy to the permit portion of the security policy. A security intelligence policy is a set of rules that defines the actions to be taken for traffic thatmatches a specific category of threat feeds, such as infected hosts, command and control servers, or botnets. By adding a security intelligence policy to the permit portion of the security policy, you can enable the SRX Series device to dynamically update the infected hosts feed based on the advanced anti-malware policy results, and block the traffic from or to the infected hosts. Options B, C, and D are not correct because they do not enable the automatic addition of infected hosts to the feed or the blocking of their communication. References: The answer can be verified from Juniper’s official documentation on security intelligence and advanced anti-malware available on their website.

Juniper ATP Cloud is a cloud-based threat detection service that protects all hosts in your network against evolving security threats. It assigns a threat level to each attacker IP address from 1 to 10, with 10 being the highest severity. Once the target threshold ismet, Juniper ATP Cloud continues looking for threats for a configurable duration from 0 to 10 minutes. This allows Juniper ATP Cloud to collect more information about the attacker and the attack vector, and to update the threat intelligence accordingly. The other options are incorrect. Option A is not configurable, and option D is not consistent with the documentation. References:
