NSK101 Sample Questions Answers

A real-time policy is a type of policy in Netskope’s CASB that allows you to control the actions that users can perform on cloud applications in real time. You can use a real-time policy to block all users from uploading data files into risky collaboration applications by specifying the following elements: the application category (such as Collaboration), the activity (such as Upload), the file type (such as Data), the risk level (such as High or Very High), and the action (such as Block). A DLP rule, a DLP profile, and a block notification are not sufficient to accomplish this task, as they are either sub-components or outcomes of a real-time policy. References: Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 5: Real-Time Policies, Lesson 1: Real-Time Policy Overview and Lesson 2: Real-Time Policy Configuration.

PCI-DSS stands for Payment Card Industry Data Security Standard, which is a set of security requirements for organizations that handle credit card data. It aims to protect cardholder data from unauthorized access, disclosure, or theft, both in transit and at rest. PCI-DSS covers various aspects of security, such as encryption, authentication, firewall, logging, monitoring, and incident response. If you are working with a large retail chain and have concerns about theircustomer data, you should use PCI-DSS as the regulatory compliance standard to govern this data. SOC 3, AES-256, and ISO 27001 are not specific to credit card data protection, although they may have some relevance to general security practices. References: [PCI-DSS], [SOC 3], [AES-256], [ISO 27001].

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].

Two pillars of CASB are visibility and compliance. CASB stands for Cloud Access Security Broker, which is a solution that provides visibility and control over cloud services and web traffic, as well as data and threat protection for cloud users and devices. Visibility is the capability to identify all cloud services in use and assess their risk factors, such as security, auditability, business continuity, etc. Compliance is the capability to ensure that cloud services and data meet the regulatory standards and policies of the organization or industry, such as GDPR, HIPAA, PCI DSS, etc. References: What Is a Cloud Access Security Broker (CASB)? | MicrosoftCASB Guide: What are the 4 Pillars of CASB? - Security Service Edge

If you consume application infrastructure (middleware) capabilities by a third-party provider, then the cloud service model that you are using in this scenario is PaaS, which stands for Platform as a Service. PaaS is a cloud service model that provides customers with a platform to develop, run, and manage applications without having to deal with the underlying infrastructure or software. PaaS typically includes middleware capabilities such as databases, web servers, development tools, integration services, etc., that customers can use to build and deploy their applications faster and easier. MaaS, DaaS, and SaaS are not cloud service models that match this scenario, as they stand for different types of services. MaaS stands for Monitoring as a Service, which is a service that provides customers with tools to monitor and manage their cloud resources and performance. DaaS stands for Desktop as a Service, which is a service that provides customers with virtual desktops that they can access from any device or location. SaaS stands for Software as a Service, which is a service that provides customers with software applications that they can use over the internet without installing or maintaining them. References: [PaaS], [MaaS], [DaaS], [SaaS].

Two primary advantages of Netskope’s Secure Access Service Edge (SASE) architecture are: no on-premises hardware required for policy enforcement and single management console. Netskope’s SASE architecture delivers network and security services as cloud-based services that can be accessed from any location and device. This eliminates the need for on-premises hardware appliances such as firewalls, proxies, VPNs, etc., that are costly to maintain and scale. Netskope’s SASE architecture also provides a single management console that allows administrators to configure and monitor all the network and security services from one place. This simplifies IT operations and reduces complexity and overhead. References: Netskope SASEWhat is SASE?

To deploy Netskope’s zero trust network access (ZTNA) solution, NPA, you need to enable Steer all Private Apps in your existing steering configuration(s) from the admin console. This will allow you to create private app profiles and assign them to your applications. NPA will then provide secure and granular access to your applications without exposing them to the internet or requiring VPNs. References: [Netskope Private Access (NPA) Deployment Guide]

To take into account some recent adjustments to CCI scoring that were made in your Netskope tenant, you can use the App Tag and App Score aspects in the UI to create a real-time protection policy. The App Tag is a label that indicates the level of enterprise readiness of a cloud app based on its CCI score. The App Score is a numerical value that represents the CCI score of a cloud app based on various criteria such as security, auditability, and business continuity. You can use these aspects to filter cloud apps by their CCI ratings and apply policies accordingly. For example, you can create a policy that blocks access to cloud apps with an App Tag of Poor or an App Score below 50. References: Netskope Cloud Confidence IndexCreating Real-Time Policies for Cloud Applications

When working with traffic from applications with pinned certificates, you should add an exception to the steering configuration to bypass them. Pinned certificates are a security technique that prevents man-in-the-middle attacks by validating the server certificates against a hardcoded list of certificates in the application. If you try to intercept or inspect the traffic from such applications, they will reject the connection or display an error message. Therefore, you should add the domains used by certificate-pinned applications as exceptions in your steering configuration, so that they are not steered to Netskope for analysis and enforcement. References: Certificate Pinned ApplicationsCreating a Steering Configuration

A tombstone file is a placeholder file that replaces the original file when it is moved to quarantine by a Netskope policy. The tombstone file contains information about the original file, such as its name, size, type, owner, and the reason why it was quarantined. The tombstone file also provides a link to the Netskope UI where the administrator or the file owner can view more details about the incident and take appropriate actions, such as restoring or deleting the file. The purpose of using a tombstone file is to preserve the metadata and location of the original file, as well as to notify the users about the quarantine action and how to access the file if needed. References: Threat Protection - Netskope Knowledge PortalNetskope threat protection - Netskope

The statement that accurately describes the difference between Source IP (Egress) and Source IP (User) address is: Source IP (Egress) is the public IP address of your Internet edge router while Source IP (User) is the address assigned to the endpoint. Source IP (Egress) is the IP address that is visible to external networks when you send traffic from your network to the Internet. It is usually the IP address of your Internet edge router or gateway that performs NAT (Network Address Translation). Source IP (User) is the IP address that is assigned to your endpoint device, such as a laptop or a smartphone, within your network. It is usually a private IP address that is not routable on the Internet. You can use these two criteria to filter traffic based on where it originates from within your network or outside your network. References: Source Address / Source Port vs Destination Address / Destination PortHow to explain Source IP Address, Destination IP Address & Service in easy way

To protect your users from malicious scripts that may be downloaded from websites, you need to use technologies that can detect and prevent malware, ransomware, phishing, and other advanced threats in web traffic. Two technologies that form a part of Netskope’s Threat Protection module, which is a feature in the Netskope platform that provides these capabilities, are sandbox and heuristics. Sandbox is a technology that allows Netskope to analyze suspicious files or URLs in a virtual environment isolated from the rest of the network. It simulates the execution of the files or URLs and observes their behavior and impact on the system. It then generates a verdict based on the analysis and blocks any malicious files or URLs from reaching your users or devices. Heuristics is a technology that allows Netskope to identify unknown or emerging threats based on their characteristics or patterns, rather than relying on predefined signatures or rules. It uses machine learning and artificial intelligence to analyze various attributes of files or URLs, such as file type, size, entropy, metadata, code structure, etc., and assigns a risk score based on the analysis. It then blocks any files or URLs that exceed a certain risk threshold from reaching your users or devices. A log parser or DLP are not technologies that form a part of Netskope’s Threat Protection module, as they are more related to discovering cloud applications or protecting sensitive data. References: [Netskope Threat Protection], Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 9: Threat Protection.

Netskope’s DLP solution is a powerful tool that can help customers protect their sensitive data from unauthorized access, exposure, or loss. One use case for Netskope’s DLP solution is to stop unintentional data movement, such as accidental uploads, downloads, or sharing of confidential files or information to or from cloud applications. Another use case for Netskope’s DLP solution is to ensure regulatory compliance, such as GDPR, HIPAA, PCI-DSS, or other industry-specific standards that require data protection and privacy measures. Netskope’s DLP solution can help customers comply with these regulations by detecting and preventing data breaches, enforcing encryption policies, applying data retention rules, and generating audit reports. Detecting malware in files before they are uploaded to a cloud application or detecting sensitive data in password protected files are not use cases for Netskope’s DLP solution, as they are more related to threat protection or file inspection capabilities. References: NetskopeSecurity Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 6: Data Loss Prevention, Lesson 1: DLP Overview.

Netskope’s security platform covers two controls: ZTNA and CASB. ZTNA stands for Zero Trust Network Access, which is a solution that provides secure and granular access to private applications without exposing them to the internet or requiring VPNs. CASB stands for Cloud Access Security Broker, which is a solution that provides visibility and control over cloud services and web traffic, as well as data and threat protection for cloud users and devices. References: Netskope PlatformNetskope ZTNANetskope CASB

A file filter is a list of file hashes that you can use to exclude files from inspection by Netskope. By adding the hash of the file that triggered a false alarm to the file filter, you can prevent it from being scanned again by Netskope and avoid generating another incident. Quarantining the file, exporting the packet capture, or looking up the hash at VirusTotal are not effective ways to prevent the same file from triggering another incident, as they do not affect how Netskope handles the file. References: Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 6: Data Loss Prevention, Lesson 2: File Filters.
