To prevent Man-in-the-Middle (MITM) attacks on an encrypted website or application, one method that you can use is certificate pinning. Certificate pinning is a technique that restricts which certificates are considered valid for a particular website or application, limiting risk. Instead of allowing any trusted certificate to be used, operators "pin" the certificate authority (CA) issuer(s), public keys or even end-entity certificates of their choice. Certificate pinning helps to prevent MITM attacks by validating the server certificates against a hardcoded list of certificates in the website or application. If an attacker tries to intercept or modify the traffic using a fraudulent or compromised certificate, it will be rejected by the website or application as invalid, even if it is signed by a trusted CA. References: Certificate pinning - IBMCertificate and Public Key Pinning | OWASP Foundation

To block all FTP connections regardless of the ports being used, the following steps should be taken using Netskope's Cloud Firewall:

Real-time Protection Policy:

Create a Real-time Protection policy where FTP is defined as the destination application.

Set the action to "Block" to ensure that any FTP traffic is blocked regardless of the port being used​​​​.

Custom Firewall App Definition:

Create a custom Firewall App Definition specifically for TCP port 21.

Define the action as "Block" to ensure any traffic directed to this port is blocked, preventing FTP access​​​​.

These configurations ensure that FTP traffic is effectively blocked, securing the network from potential threats and unauthorized data transfers via FTP​​​​.

Creating a policy group as a logical collection of Real-time Protection policies provides several benefits:

To split up policies by region or business unit: This allows for more granular control and management of policies based on organizational structure. Each region or business unit can have its own set of policies tailored to its specific needs and compliance requirements.

To simplify workflow, allowing exact access to a specific set of policies: Policy groups help streamline the management process by grouping related policies together. This simplifies the workflow for administrators by providing them with access to only the relevant policies they need to manage, reducing complexity and potential for errors.

To monitor IPsec tunnels to a Netskope data plane, it is essential to ensure the stability and responsiveness of the tunnels. The recommended steps involve enabling monitoring mechanisms that detect and respond to tunnel failures. Here’s a detailed explanation of the two recommended steps:

Enable IKE Dead Peer Detection (DPD) for each tunnel:

Explanation: IKE Dead Peer Detection (DPD) is a method used to detect if the peer (remote endpoint of the tunnel) is no longer available or reachable. By enabling DPD, the device can automatically detect and tear down the IPsec tunnel if the peer does not respond, allowing for quick re-establishment of the tunnel if needed.

Implementation: Configure DPD in the IPsec settings of the perimeter device. This ensures that if the Netskope data plane is unreachable, the tunnel is automatically terminated and re-negotiated.

Send ICMP requests to the Netskope location's Probe IP:

Explanation: Sending ICMP requests (ping) to the Netskope location's Probe IP helps in monitoring the availability and latency of the connection to the Netskope data plane. If the ICMP requests fail, it indicates a potential issue with the connectivity.

Implementation: Set up regular ICMP requests (ping) from the perimeter device to the Netskope Probe IPs. This allows for continuous monitoring of the tunnel’s health and immediate detection of connectivity issues.

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: Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 6: Data Loss Prevention, Lesson 1: DLP Overview.

When reviewing files affected by malware in the Netskope UI under Incidents -> Malware, you have the following options:

Identify the exposure of the file identified as malware: This allows you to see where the malware has spread within the organization, which users or systems are affected, and any potential data exposure resulting from the malware.

Determine the Detection Engine used to identify the malware: Netskope provides details on which detection engine (such as AV, sandboxing, or other heuristic engines) identified the malware. This helps in understanding the threat vector and the reliability of the detection.

Downloading the original malware file (option A) is generally not recommended for security reasons and may not be supported directly from the Netskope UI. Remediation of compromised devices (option C) would typically be handled through endpoint security solutions rather than directly from the Netskope UI.

Netskope’s NewEdge Security Cloud Network Infrastructure is a global network that powers the Netskope Security Cloud, providing real-time inline and out-of-band API-driven services for cloud and web security. Three statements that are correct about Netskope’s NewEdge Security Cloud Network Infrastructure are:

It includes direct peering with Microsoft and Google in every data center. This means that Netskope has established high-speed, low-latency connections with these major cloud service providers, ensuring optimal performance and user experience for their customers. Direct peering also reduces the risk of network congestion, packet loss, or routing issues that may affect the quality of service.

It is a private security cloud network that is massively over provisioned, highly elastic, and built for scale. This means that Netskope owns and operates its own network infrastructure, without relying on third-party providers or public cloud platforms. Netskope has invested over $150 million to build the world’s largest and fastest security private cloud, with data centers in more than 65 regions and growing. Netskope can dynamically scale its network capacity and resources to meet the growing demand and traffic volume of its customers, without compromising on security or performance.

It delivers a single, unified network with no surcharges or reliance on public cloud infrastructure or virtual PoPs. This means that Netskope provides a consistent and transparent network service to its customers, regardless of their location or device. Netskope does not charge any additional fees or hidden costs for accessing its network services, unlike some other providers that may impose surcharges based on geography or bandwidth usage. Netskope also does not use virtual points of presence (PoPs) that are hosted on public cloud platforms, which may introduce latency, complexity, or security risks.

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

When using the Netskope Compromised Credentials feature, administrators can gain valuable insights into security incidents related to compromised credentials. The insights provided by this feature include:

Compromised usernames: This information helps identify which user accounts have been compromised, allowing administrators to take necessary actions such as resetting passwords and notifying affected users.

Breach information source: Netskope provides details on the source of the breach, such as which third-party service or data breach resulted in the compromise of credentials. This helps in understanding the context of the breach and implementing measures to prevent future incidents.

While compromised passwords (option C) are indirectly involved, they are not explicitly listed as an insight provided by this feature. Similarly, affected managed applications (option D) are related but not directly part of the primary insights.
