Exactprep JN0-636 Questions

The security feature that achieves the objective of identifying potential threats within SSL-encrypted sessions without requiring SSL proxy to decrypt the session contents is encrypted traffic insights. Encrypted traffic insights (ETI) is a feature of Juniper ATP Cloud that helps you to detect malicious threats that are hidden in encrypted traffic without intercepting and decrypting the traffic. ETI uses machine learning and behavioral analysis to identify anomalies and suspicious patterns in the encrypted traffic metadata, such as the SSL/TLS handshake, the certificate, the cipher suite, and the session duration. ETI can also leverage third-party feeds and threat intelligence from Juniper ATP Cloud to correlate the encrypted traffic with known indicators of compromise (IoCs). ETI can provide insights into the risk level, the threat category, the threat location, and the threat time of the encrypted traffic. ETI can also trigger mitigation actions, such as blocking, quarantining, or alerting, based on the threat severity and the policy configuration. ETI can help you to improve your security posture and visibility without compromising the privacy and performance of the encrypted traffic. References: Juniper Security, Professional (JNCIP-SEC) Reference Materials source and documents: https://www.juniper.net/documentation/en_US/junos/topics/concept/security-atp-cloud-encrypted-traffic-insights-overview.html

The solution to this problem is to enable address persistence. This will ensure that the same external IP address is used for multiple sessions between an internal host and an external host. This will result in only one authentication being required, as the same external IP address will be used for all sessions.

According to the Juniper documentation, Juniper ATP Cloud supports the following modes:

• Layer 3 mode: In this mode, the SRX Series device acts as a Layer 3 gateway and routes traffic between different subnets. The SRX Series device performs NAT and security policy enforcement on the traffic and sends a copy of the traffic to Juniper ATP Cloud for analysis. This mode is suitable for networks that have multiple subnets and require NAT and firewall functions1
• Transparent mode: In this mode, the SRX Series device acts as a Layer 2 bridge and forwards traffic between the same subnet. The SRX Series device does not perform NAT or security policy enforcement on the traffic, but sends a copy of the traffic to Juniper ATP Cloud for analysis. This mode is suitable for networks that have a single subnet and do not require NAT or firewall functions1

The other two modes, global mode and private mode, are not supported by Juniper ATP Cloud. Global mode is a configuration option for Juniper ATP Appliance, which is an on-premises solution that provides threat detection and prevention. Private mode is a configuration option for Juniper ATP Private Cloud, which is a cloud-based solution that provides threat detection and prevention within a private network23
