Explanation:
Understanding the Policies in the Exhibit: The exhibit displays two policies configured on the Juniper SRX device for traffic between the trust zone and the dmz zone.
Policy 1:
Name: Trust-DMZ-Access
State: Enabled
Source Address: Trust-Net
Destination Address: DMZ-Net
Applications: junos-ftp, junos-ping
Action: permit
Log: Enabled
Policy 2:
Name: Trust-DMZ-Block
State: Enabled
Source Address: Trust-Net
Destination Address: DMZ-Net
Applications: junos-ssh
Action: deny, log
Analysis of Each Option:
Option A:
The Trust-DMZ-Access policy explicitly permits traffic for the junos-ftp and junos-ping applications.
This is validated by the action permit in the policy configuration.
Correct.
Option B:
This is incorrect because the Trust-DMZ-Access policy permits FTP and ping traffic rather than denying it.
Incorrect.
Option C:
The Trust-DMZ-Block policy explicitly denies traffic for the junos-ssh application.
Therefore, SSH access is not permitted.
Incorrect.
Option D:
The Trust-DMZ-Block policy denies SSH traffic from the Trust-Net to the DMZ-Net.
This is validated by the action deny.
Correct.
Juniper Security
Reference: Security Policy Overview: Security policies in Junos OS are used to control and filter traffic between security zones. Each policy defines:
Source and destination zones
Source and destination addresses
Applications or services
Action: permit, deny
Logging options
Policy Action Details:
permit: Allows the specified traffic.
deny: Blocks the specified traffic.
Application Identification:
Juniper SRX uses predefined application identifiers (junos-ftp, junos-ping, junos-ssh) for traffic matching.
Policy Evaluation Order: Policies are evaluated in sequence by their index number or sequence number. In this exhibit:
Trust-DMZ-Access is evaluated first (Sequence number: 1).
Trust-DMZ-Block is evaluated next (Sequence number: 2).
Conclusion: Based on the exhibit, FTP and ping traffic is permitted under Trust-DMZ-Access, and SSH traffic is denied under Trust-DMZ-Block. The answers to the question are therefore:
A. Correct
D. Correct
Refer to the Juniper Security Policy Documentation for more details on configuring and managing policies.
정답:
Explanation:
According to the Juniper SRX Series Services Guide, the null zone is a predefined security zone that is created on the SRX Series device when it is booted. Traffic that is sent to or received on an interface in the null zone is discarded. The null zone is not a functional security zone, so you cannot enable or disable it.
정답:
Explanation:
By default, TCP has a 30-minute idle timeout, and UDP has a 60-second idle timeout. Additionally, known IP protocols have a 30-minute timeout, whereas unknown ones have a 60-second timeout. Setting the inactivity timeout is very useful, particularly if you are concerned about applications either timing out or remaining idle for too long and filling up the session table. According to the Juniper SRX Series Services Guide, this can be configured using the 'timeout inactive' statement for the security policy.

Explanation:
Juniper ATP should be configured with C&C feeds that contain lists of malicious domains and IP addresses in order to prevent IP cameras from becoming zombies in a DDoS attack.
This is an important step to ensure that the IP cameras are protected from malicious requests - and thus, they will not be able to be used in any DDoS attacks against the facility.
정답:
Explanation:
This is necessary to ensure that the application firewall can properly identify the application and the correct security policies can be applied before allowing any traffic to pass through.
If the first packet was allowed to pass without first being identified, then the application firewall would not know which security policies to apply - and this could potentially lead to security vulnerabilities or breaches. So it's important that the first packet is held until the application is identified.

Explanation:
Junos-host and null are two non-configurable zones that exist by default on an SRX Series device. Junos-host is the default zone for all internal interfaces and services, such as management and other loopback interfaces. The null zone is used to accept all traffic that is not explicitly accepted by other security policies, and is the default zone for all unclassified traffic. Both zones cannot be modified or deleted.
정답:
Explanation:
Juniper Enhanced Web Filtering is a web filtering solution that uses a direct Internet-based service for URL categorization. This service allows Enhanced Web Filtering to quickly and accurately categorize URLs and other web content, providing real-time protection against malicious content. Additionally, Enhanced Web Filtering is able to provide detailed reporting on web usage, as well as the ability to define and enforce acceptable use policies.
정답:
Explanation:
User-defined security zones allow users to configure multiple security zones and share them between routing instances. This allows users to easily manage multiple security zones and their associated policies. For example, a user can create a security zone for corporate traffic, a security zone for guest traffic, and a security zone for public traffic, and then configure policies to control the flow of traffic between each of these security zones. Transit traffic can also be managed using user-defined security zones, as the policies applied to these zones will be applied to the transit traffic as well.
정답:
Explanation:
The two correct statements about the Junos OS CLI are that the default configuration requires you to log in as the admin user, and that most Juniper devices identify the root login prompt using the > character. The factory-default login assigns the hostname "juniper" to the device and the root login prompt is usually identified with the % character. More information about the Junos OS CLI can be found in the Juniper Networks technical documentation here: https://www.juniper.net/documentation/en_US/junos/topics/reference/command-summary/cli-overview.html.
정답:
Explanation:
The correct statement about Junos security policies is that they enforce rules that should be applied to traffic transiting an SRX Series device. Security policies control the flow of traffic between different zones on the SRX Series device, and dictate which traffic is allowed or denied. They can also specify which application and service requests are allowed or blocked. More information about Junos security policies can be found in the Juniper Networks technical documentation here: https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/security-policies-overview.html.
