The three technologies that describe the primary cloud service models as defined by the National Institute of Standards and Technology (NIST) are Platform as a Service (PaaS), Software as a Service (SaaS), and Infrastructure as a Service (IaaS). These service models are based on the type of computing capability that is provided by the cloud provider to the cloud consumer over a network. According to NIST, these service models have the following definitions:

• Platform as a Service (PaaS): The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment.
• Software as a Service (SaaS): The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
• Infrastructure as a Service (IaaS): The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls).

The term that correctly defines the Zero Trust security model is least privilege access. The Zero Trust security model is a modern security strategy based on the principle: never trust, always verify. Instead of assuming everything behind the corporate firewall is safe, the Zero Trust model assumes breach and verifies each request as though it originates from an open network. One of the core principles of the Zero Trust model is to use least privilege access, which means granting users or systems only the minimum level of access they need to perform their tasks, and only for a limited time. This helps reduce the attack surface and minimize the impact of a potential breach. References: Zero Trust Security - microsoft.comWhat is Zero Trust Security? Principles of the Zero Trust Model

To collect the logs from the client machine when you have an issue with the Netskope client connecting to the tenant, two ways that you can use are: from the Netskope client UI About page and from the command line using the nsdiag command. From the Netskope client UI About page, you can click on the “Collect Logs” button to generate a zip file containing all the relevant logs and configuration files from the client machine. You can then send this zip file to Netskope support for troubleshooting. From the command line, you can use the nsdiag command with various options to collect different types of logs and diagnostic information from the client machine. For example, you can use nsdiag -l to collect all logs, nsdiag -c to collect configuration files, nsdiag -t to collect traffic statistics, etc. You can also use nsdiag -h to see all available options and usage instructions. You can then send the output files to Netskope support for troubleshooting. References: Netskope Client Configuration overviewInstall and Test the Client - Netskope Knowledge Portal

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 tunnelsdo 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.
