The configuration shown in the exhibit is for a Juniper SRX Series firewall. The session-init parameter is used to control how the firewall processes unknown traffic flows. With the session-init parameter set to 300, any traffic flows that the firewall does not recognize will be dropped after 300 milliseconds. Additionally, every session that enters the device, whether it is known or unknown, will generate an event, which can be used for logging and troubleshooting purposes. The session-lose parameter is used to control how the firewall handles established sessions that are terminated.

In this scenario, you should use the ATP Cloud Ul to create a custom profile and update the scan limit for executable files to 30 MB. This will ensure that executable files up to 30 MB can be scanned, while at the same time minimizing the change in scan time for other file types. To do this, log in to the ATP Cloud Ul and go to the Profiles tab. Click the Create button to create a new profile, and then adjust the scan limits for executable files to 30 MB. Once you have saved the custom profile, you can apply it to the desired systems and the new scan limit will be in effect.

Log entries would be generated in two situations: at session initialization and at session close. At session initialization, the log entry would include details about the connection, such as the source and destination IP addresses, the service being used, and the action taken by the security policy. At session close, the log entry would include details about the connection, such as the duration of the session, the bytes sent/received, and the action taken by the security policy. For more information, you can refer to the Juniper Security documentation athttps://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/security-log-configuration.html.

Two possible reasons for this error are that the SSL proxy certificate ID does not exist, or the SSL proxy certificate ID is part of a blocklist. If the SSL proxy certificate ID does not exist, you will need to generate a new certificate. If the SSL proxy certificate ID is part of a blocklist, you will need to contact the source of the blocklist to remove it. Additionally, you may need to check that the SSL proxy certificate ID has the correct renegotiation option set, as this is necessary for proper server protection. For more information, you can refer to the Juniper Security documentation athttps://www.juniper.net/documentation/en_US/junos/topics/reference/configuration-statement/security-ssl-proxy-configuration.html.

Dynamic analysis is not always necessary to determine if a file contains malware, as the ATP Cloud uses a cache lookup to quickly identify known malicious files. If the cache lookup determines that a file contains malware, static analysis is not performed to verify the results. This information can be found on the Juniper website here:https://www.juniper.net/documentation/en_US/release-independent/security/jnpr-security-srx-series/information-products/topic-collection/jnpr-security-srx-resources.html#id-jnpr-security-srx-resources-atp-cloud.

Schedulers can be defined and reused by multiple policies, allowing for more efficient management of policy activation and deactivation. This can be particularly useful for policies that need to be activated during specific time periods, such as business hours or maintenance windows.

To exclude traffic from being examined by IPS, you can use the source IP address and/or destination port as criteria for the exemption. This is achieved by configuring an IPS-exempt rule base that includes specific exemption rules based on these criteria.

AppQoS (Application Quality of Service) is a Junos OS feature that provides advanced control and prioritization of application traffic. With AppQoS, you can classify application traffic, assign a forwarding class to the traffic, and apply quality of service (QoS) policies to the traffic. You can also re-write DSCP values and reserve bandwidth for important applications. However, AppQoS does not re-write the TTL or rate-limit traffic.

The early-ageout configuration specifies the timeout value, in seconds, that will be applied once the high-watermark value is met. The high-watermark configuration specifies the percentage of how much of the session table can be allocated before applying a more aggressive age-out timer. This ensures that the session table does not become full and cause traffic issues, and also ensures that existing flows are aged out quickly when the table begins to get close to being full.
