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.

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

When creating a real-time policy for cloud applications, you can use access method and device classification as source criteria, in addition to users, groups, and organizational units. Access method refers to how the user accesses the cloud application, such as browser, sync client, mobile app, etc. Device classification refers to the type of device used by the user, such as managed or unmanaged, Windows or Mac, etc. These criteria can help you define granular policies based on different scenarios and risks. References: [Creating Real-Time Policies for Cloud Applications]
