JN0-231 Security-Associate (JNCIA-SEC) Questions and Answers

Juniper ATP Geo IP can help to accomplish this task by using geolocation services to determine the geographical location of IP addresses. As IP prefixes get allocated to the countries that you have specified, the Geo IP solution will automatically update the configured firewall policies to block any traffic that is coming from those specific countries.

This is a great solution for blocking specific countries - as it will allow for a more personalized and targeted approach to firewall policies - and thus, to increase the effectiveness of the solution at blocking potential malicious traffic.

In this scenario, you should implement Juniper ATP (Advanced Threat Prevention). Juniper ATP provides user-based enforcement of security policies without the requirement of certificates and supplicant software. It uses a combination of behavioral analytics, sandboxing, and threat intelligence to detect and respond to advanced threats in real time. Juniper ATP provides robust protection against targeted attacks, malicious insiders, and zero-day malware. For more information, please refer to the Juniper ATP product page on Juniper's website.

Junos Space is a management platform that provides a single pane of glass view of SRX Series devices dispersed throughout locations in your organization. It provides visibility into the security policies of the devices, allowing you to quickly identify and respond to security threats. Additionally, it provides the ability to manage multiple devices remotely and in real-time, enabling you to quickly deploy and update security policies on all devices. For more information, please refer to the Juniper Networks Junos Space Network Director User Guide, which can be found on Juniper's website.

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.

Only static NAT with pool ensures both traffic initiated from inside and outside networks use the same IP address.
