To mitigate malicious scripts from being downloaded into your corporate devices every time a user goes to a website, you need to use Netskope’s threat protection features to block or isolate potentially harmful web traffic. Two actions that would help you accomplish this task while allowing the user to work are: block malware detected on download activity for all remaining categories and block known bad websites and enable RBI to uncategorized domains. The first action will prevent any files that contain malware from being downloaded to your devices from any website category, except those that are explicitly allowed or excluded by your policies. The second action will prevent any websites that are classified as malicious or phishing by Netskope from being accessed by your users and enable Remote Browser Isolation (RBI) to uncategorized domains, which are domains that have not been assigned a category by Netskope. RBI is a feature that allows users to browse websites in a virtual browser hosted in the cloud, without exposing their devices to any scripts or content from the website. Allowing the user to browse uncategorized domains but restrict edit activities or allowing a limited amount of domains and block everything else are not effective actions, as they may either limit the user’s productivity or expose them to unknown risks. References: [Netskope Threat Protection], [Netskope Remote Browser Isolation].

To update a File Profile with malicious file hashes in the Netskope platform, an administrator can use the following methods:

Upload a CSV file of malicious file hashes: Administrators can prepare a CSV file containing the malicious file hashes and upload it to the platform. This method allows for bulk updates of the file profile with multiple hashes at once.

Input a list of malicious file hashes: Administrators can manually input a list of malicious file hashes directly into the platform. This method is useful for adding individual hashes or making small updates to the file profile.

These methods ensure that the file profile is updated with the latest malicious file information, enabling the platform to detect and block known threats effectively.

When designing an architecture with Netskope Private Access, the Netskope Publisher is the element that guarantees connectivity between the Netskope cloud and the private application. The Publisher acts as a gateway, securely connecting users to private applications hosted on-premises or in data centers.

Netskope Publisher: This component facilitates secure access to private applications by connecting the Netskope cloud with the internal network. It ensures that users can access private applications seamlessly while maintaining security and compliance.

=================

In this scenario, there are three probable causes for the issue of users not being able to access external websites from their browsers after attempting to steer traffic to Netskope using GRE tunnels. One cause is that the configured GRE peer in the Netskope platform is incorrect, which means that the Netskope POP that is supposed to receive the GRE traffic from the customer’s network is not matching the IP address of the customer’s router that is sending the GRE traffic. This will result in a failure to establish a GRE tunnel between the customer and Netskope. Another cause is that the corporate firewall might be blocking GRE traffic, which means that the firewall rules are not allowing the GRE protocol (IP protocol number 47) or the UDP port 4789 (for VXLAN encapsulation) to pass through. This will result in a failure to send or receive GRE packets between the customer and Netskope. A third cause is that the route map was applied to the wrong router interface, which means that the configuration that specifies which traffic should be steered to Netskope using GRE tunnels was not applied to the correct interface on the customer’s router. This will result in a failure to steer the desired traffic to Netskope. The pre-shared key for the GRE tunnel is incorrect is not a probable cause for this issue, as GRE tunnels do not use pre-shared keys for authentication or encryption. Netskope does support GRE tunnels, so this is not a cause for this issue either. References: [Netskope Secure Forwarder], Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 3: Steering Configuration, Lesson 3: Secure Forwarder.
